How wealthy in natural resource leads environmental sustainability in developing economies? An empirical investigation

This study investigates the impact of income generated from natural resources on environmental sustainability and analyses the moderating role of institutional quality in carbon emissions function. An extensive dataset from 61 developing nations covering the years 2000–2018 has been taken, which uses a dynamic heterogeneous panel data model. Our study follows a rigorous methodology by applying the pooled mean group estimator. An extensive examination of the impacts over the short run and long run is possible using this method. This study reveals multifaceted findings: in the short run, the effect of institutional quality and natural resources revenues on carbon emissions is insignificant, implying that such factors have a relatively minor impact. The long-term examination reveals that income derived from natural resources causes a spike in carbon emissions, which causes environmental deterioration and climate change. Strong institutional quality can significantly mitigate the adverse effects of correlation between revenues from natural resources and carbon emissions, which have been observed. The study's moderating effect of natural resources richness, which gradually reduces institutional quality's ability to reduce carbon emissions, is a crucial finding. Our study significantly advances the field of environmental economics, especially when discussing sustainable development in emerging nations with abundant natural resources. It emphasizes the delicate balance that must be struck between preserving efficient environmental governance and maximizing the richness of natural resources. Our findings underscore the crucial need for developing nations to strengthen their institutional frameworks and capacities and have substantial policy implications. These steps are essential to ensuring that the use of natural resources is in line with environmental sustainability objectives, turning resource curses into blessings for long-term development and environmental preservation. This research opens the door to sector-specific impacts and personalized policy interventions in resource-rich developing economies.

GLOBAL EXPERIENCE OF DEVELOPING COUNTRIES IN FORMING INNOVATIVE MECHANISMS OF GREEN ECONOMIC GROWTH

The article examines the international experience of developing countries in creating and implementing innovative mechanisms to achieve green economic growth. The necessity of implementing such mechanisms to ensure sustainable economic development is substantiated. It is argued that innovative approaches are key to preserving the ecological balance and improving the well-being of the population. It was established that the effective use of natural resources requires the integration of environmental and economic strategies. Based on the set goal, various models and practices of green growth applied in developing countries are considered. Successful examples are studied and found that their adaptation can contribute to global sustainable development. Further perspectives of research should be aimed at studying the possibilities of scaling and optimization of these innovative mechanisms in the context of global challenges. It was determined that each country has its own characteristics due to the level of development of the country, its geographical location, the presence of natural resources and the specifics of the concepts, models and development tools used, which correspond to national priorities and accumulated experience, and therefore the transition to a "green" economy for different states will take place under different scenarios. It illustrates the benefits and challenges of implementing green innovation for developing countries using the example of China and its chart of China's key industrial strategies for green manufacturing. During the research of this topic, it was found that the consistent and effective implementation of the principles of "green" investment, as well as "green" development in general, is possible only in a regulatory environment, transparent and fair, developed in accordance with the principle of the rule of law, with independent courts procedures, with the participation of independent market regulators acting in accordance with national interests, respecting the rights of investors and consumers. On the other hand, for their principles of implementation a vital role is played by socially responsible business behavior, one of the key indicators of which is the attitude of business to environmental issues, the efficiency of resource use and energy efficiency, and the disclosure of socially significant non-financial information. It is noted that in Ukraine climate and investment policies function separately from each other, and sometimes their goals are mutually contradictory, which prevents or slows down investments in the development of "green" infrastructure.

Comparative Chemical Study of Three Different Market Samples of an Important Clay Mineral Drug “Gil-E-Makhtum” with A Brief Ancient Description of Earth's Natural Resources

The medical use of earth's natural resources or mineral drugs is probably as old as the history of man kinds and has been used widely for the ailments of many diseases despite knowing the presence of chemical constituents or pharmacological activities of that particular substance but in the present era, with the modern techniques much more research work has been done to know the active components and their pharmacological properties which could have now been used in the modern medicine. Among the various earth natural resources or mineral drugs Gil-e-Makhtum (Sealed earth or the type of clay) also known by the name Lemnian earth, is a medicine in the shape of a stamped clay tablet (Sphragis) from Lemons, northeastern Greece, was much valued in antiquity and is utilized as such as well as an ingredient in the number of compound formulations in the Unani system of medicine for the treatment of various diseases. In this paper with the description of the brief history of Earth’s Natural Resources, the comparative chemical study of three different market samples of Gil-e-Makhtum was carried out by following some parameters of qualitative analysis and quantitative estimations. The analysis included Loss of weight on drying at 105oC, solubility in 1 normal hydrochloric acid and water, total ash, acid insoluble ash, bulk density, and tapped density. Besides, some major estimations e. g. Hematite (Fe2O3), Alum (Al2O3), Quartz (SiO2), and Calcium oxide (CaO) were also carried out.

Boosting mortar performance: use of recycled brick sand for enhanced mechanical properties

The construction industry is constantly seeking ways to become more sustainable. One area of exploration is mortar technology, where researchers are looking at replacing traditional components with alternative materials and adding a superplasticizer to improve mechanical strength and reduce the use of natural resources. The present study focuses on substituting brick waste sand in mortar at different replacement ratios of 0%, 10%, 30%, and 50%. The main objective is to investigate the effect of this substitution material on the properties of the mortar. The researchers have conducted compression and flexural tensile tests on prismatic specimens (4 x 4 x 16 cm³) at various curing periods (2, 7, and 28 days). The results showed that replacing 50% of sand with brick wastes significantly improved mortar properties. However, replacing more than 50% of the sand hurt the workability of the mortar. This study highlights the potential of using brick waste sand as an alternative to sand in mortar production, promoting resource conservation and sustainable construction. The findings suggest that while a 50% replacement ratio is beneficial, it is essential to carefully consider the mix design to maintain workability and overall performance.

Electricity Generation at Gas Distribution Stations from Gas Surplus Pressure Energy

At gas distribution stations (GDSs), the process of throttling (pressure reduction) of natural gas occurs on gas pressure regulators without generating useful energy. If the gas expansion process is created in a turbine, to the shaft where an electric generator is connected, then electricity can be obtained. At the same time, the recycling of secondary energy resources is provided, which is an important component in the efficient use of natural resources. The obtained electric power can be supplied to the external power grid and/or used for the GDS’s own needs. The process of generating electricity at the GDS from gas overpressure energy is an environmentally friendly, energy-saving technology that ensures an uninterrupted, autonomous operation of the GDS in the absence of an external energy supply. The power needs of a GDS with regard to electricity are relatively small (5 ÷ 20 kW). Expansion in throttling devices or turbine flow paths leads to gas cooling with a possible hydrate formation. It is prevented via gas preheating or vortex expansion equipment that keeps the further gas temperature at a necessary level. Turbogenerators can be created on the basis of vortex expansion turbomachines, which have many advantages compared to turbomachines of other types. This article studies how gas pressure (outlet: gas distribution station) and gas preheating (inlet: vortex expansion machine) influence turbogenerator parameters. Nine turbogenerator variants for the power needs of gas distribution stations have been assessed.

A comparative study into the effect of spent coffee powder and ash on improving the mechanical properties of bitumen

Nowadays, waste and renewable materials are used to modify bitumen and asphalt, reduce costs, decrease the use of natural resources, and maintain ecological balance, and have thus received much attention. This study aimed to improve the rheological properties of bitumen and reduce spent coffee grounds' (SCG) waste by partially replacing it with SCG powder and ash. SCG powder and ash were added in percentages of 0, 1, 3, 5, and 8 wt percent of bitumen to check the properties of control and modified bitumens. Microstructural properties were evaluated by Fourier transform infrared spectroscopy, thermal gravimetric analysis, X-ray fluorescence spectroscopy (XRF), and scanning electron microscopy (SEM). Penetration, softening point, and ductility tests were performed to check the physical properties of bitumens, along with the storage stability test. Rheological tests (viscosity, bending beam rheometer (BBR), dynamic shear rheometer (DSR), multiple stress creep and recovery (MSCR), and linear amplitude sweep (LAS) were also carried out. According to the BBR results, adding SCG powder up to −12 °C and adding SCG ash up to −6 °C increased the resistance to low temperatures. Based on DSR and MSCR results, SCG, either in the form of ash or powder, increased the resistance to rutting, and adding SCG ash improved the high temperature performance of bitumen by 1 grade. At 64 °C, adding 8 % of SCG powder increased the rutting resistance by 43 %, and adding SCG ash raised the rutting resistance by about 113 %. LAS results also showed that SCG ash outperforms SCG powder in fatigue. Although both SCG powder and ash performed well in high, moderate, and low temperatures, SCG powder performed better in cold regions, and SCG ash performed better in regions with temperate and tropical climates.

The article provides a literature review of mycofloral analysis of agarics and medicinal mushrooms distributed in the Borovoe and Kokshetau national parks. As a result of the literature review, 15 species of fungi belonging to 4 genera and 9 genera of the genus Agaricales were identified. Of these, edible -5, inedible – 3, poisonous – 1 species. Collection of Macromycetes during the expedition was collected by route method from Borovoe and Kokshetau national parks. The collection, sorting, drying, packaging and transportation of the collected material was carried out in accordance with the methods of mycology and Botany. 30-40 min at 45-50° t for the purpose of disinfection of the collected samples. in between, a heating cabinet (water heater) was used. Each processed sample is stored in a specially designed box with the date, place, time of collection and herbarium number. The external morphological description of the fruiting body of the fungus was made by visual observation, and for determining the microscopic structure, features of spores, we used the Mikmed-1 microscope and cameras connected to it Exilim-S880, SAMSUNG-ES65, Canon-PC1474. To separate the tissue particle from the fruit body of the fungi, a fertile, non-darkening, young specimen was obtained. A cube-shaped or triangular pyramidal "tissue" particle was cut out of the pre-cleaned fruit bodies through a scalpel and planted in a nutrient medium (oblique agar) through an inoculation needle. Isolation was carried out from different parts of the fruit body: caps, legs, places of transition of the cap to the stem. The growth and development of the selected clean crop will depend on the composition of the nutrient medium. The cortical medium we used was diverse, including "Chapeka–Doxa", "Murashige Skuga" and potato-glucose agar. As a result of the study, more than 25 mushroom samples were collected. As a result, 15 species from 9 relatives from 4 genera belonging to the family of cap mushrooms Agaricales were identified. 4 genera have been identified in the agaricales series: Agaricaceae, Russulaceae, Tricholomataceae, Strophariaceae. As a result of summing up the results of the conducted research, we came to the following conclusions: During the study, the characteristics of morphological forms of fungi were developed. Based on the obtained morphometric characteristics, the species of fungi were determined using special determinants. As a result of studying all the collected mushrooms in the Kokshetau and Borovoe National parks, 15 species of fungi from 9 genera belonging to the genus Agaricales were identified. Of these, 1 is poisonous, 5 is edible, and 3 are inedible. A species synopsis of Agaricales fungi in the Kokshetau and Borovoe National parks has been compiled. All the results and data obtained are of great importance for the effective use of natural resources and their protection.

Mining corruption, environmental damage, and the increasing unauthorized properties of state officials

Indonesia is blessed with natural resources in the form of minerals and coal. Their use must be directed towards the greatest welfare and prosperity of the people based on the 1945 Constitution. However, what is currently happening is the opposite. the Attorney General revealed case of alleged corruption in the trading system of tin commodities in the Bangka Belitung region. The suspects include businessmen, directors, crazy rich Indonesians, and artists who are now increasingly attracting public attention. The total state losses were equivalent to $16,667 billion USD. This research used a sociological legal research model. The research object was the legal behavior in the reality of society. It was found that to formulate appropriate law enforcement for mining corruption, Friedman’s legal system theory approach was used. This theory includes legal structures, with good synergy from each law enforcement institution. Concerning the legal substance, apart from using the Corruption Crime Law, perpetrators also need to be impoverished by regulating the crime of money laundering. In terms of legal culture, state officials should uphold ethics and integrity to achieve good governance. Meanwhile, restoration of environmental damage resulting from mining activities can begin with future environmental policies that are directed towards ensuring the safety and health of the human life as well as controlling the wise use of natural resources. The integration of environmental law and Islam can be carried out using a prophetic ethical approach. The prophetic paradigm interprets nature as something sacred as humans only borrow it and manage.

Chemical and Physical Characterization of Three Oxidic Lithological Materials for Water Treatment

Water treatment necessitates the sustainable use of natural resources. This paper focuses on the characterization of three oxidic lithological materials (OLMs) with the aim of utilizing them to prepare calcined adsorbent substrates for ionic adsorption. The three materials have pH levels of 7.66, 4.63, and 6.57, respectively, and organic matter contents less than 0.5%. All of the materials are sandy loam or loamy sand. Their electric conductivities (0.18, 0.07, and 0.23 dS/m) show low levels of salinity and solubility. Their CEC (13.40, 13.77, and 6.76 cmol(+)kg) values are low, similar to those of amphoteric oxides and kaolin clays. Their aluminum contents range from 7% up to 12%, their iron contents range from 3% up to 7%, their titanium contents range from 0.3% to 0.63%, and their manganese contents range from 0.007% up to 0.033%. The amphoteric oxides of these metals are responsible for their ionic adsorption reactions due to their variable charge surfaces. Their zirconium concentrations range from 100 to 600 mg/g, giving these materials the refractory properties necessary for the preparation of calcined adsorbent substrates. Our XRD analysis shows they share a common mineralogical composition, with quartz as the principal component, as well as albite, which leads to their thermal properties and mechanical resistance against abrasion. The TDA and IR spectra show the presence of kaolinite, which is lost during thermal treatments. The results show that the OLMs might have potential as raw materials to prepare calcined adsorbent substrates for further applications and as granular media in the sustainable treatment of both natural water and wastewater.

Application of Life Cycle Assessment in Beer Production: Systematic Review

The production of beer, a beverage of global cultural and industrial importance, has a significant impact on the environment due to the use of natural resources and the emissions generated during the various stages of the production process. Therefore, this article examines the sustainability of beer production through a review of literature articles that have used Life Cycle Assessment (LCA) to assess its environmental impacts. A systematic literature review was conducted by selecting peer-reviewed articles published between 2001 and July 2024 using databases such as Scopus and Google Scholar. The search included studies analyzing different stages of the beer life cycle, from raw material production to packaging and distribution, using specific keywords related to LCA and brewing. The results showed that energy use and packaging are the two critical aspects identified in the review, which represent a significant part of the environmental footprint. However, it is important to note that the available studies on the subject are few and heterogeneous and they use different methodologies, impact categories, and functional units, which complicates the comparison and synthesis of results, limiting the ability to draw definitive conclusions. Recommendations were made to improve sustainability, including the adoption of more efficient technologies, the use of recycled materials for packaging, and the implementation of sustainable agricultural practices. These strategies could aim to significantly reduce the overall environmental impact of beer production.

Strategic incentives and natural capital accounting for sustainable supply chain management: Measuring reputational impacts and consumers’ perceptions of the use of water through behavioural experimental studies

Within a sustainable supply chain management approach, this study investigates strategic issues that can either favour or impede the implementation of natural capital accounting. Among other things, the originality of such consists of the joint consideration of sustainability, operational, and reputational issues, forging the link between measuring the use of natural resources and preserving companies' intangible capital. More specifically, through two scenario-based behavioural experiments with a total sample of 252 consumers in the UK, we analyse how information regarding the use of water (i.e., water footprint) affects firms' reputation (i.e., trust, attitude towards the firm, word-of-mouth, brand avoidance). We also investigate consumers' perceptions when companies seek to (1) increase the transparency of their consumption of natural capital (i.e., a conceptual proxy for the adoption of natural capital accounting) and (2) rationalize this consumption (i.e., a goal aligned with the objectives of natural capital accounting). The method employed is adequate as it allows the detection and measurement of respondents' perceptions of specific issues presented in the different scenarios. The choice of the UK as the setting reflects the importance of the country in the fashion industry, as it has a solid consumer base and is home to several international fashion brands. The supply chain management scope refers to the link between water consumption (which often takes place in the production of raw materials (e.g., cotton) and in transformation processes (e.g., fabric dyeing, tanning) by suppliers), fashion brands' reputation, and consumers' perceptions, with the joint consideration of these four phases sustaining the delimitation. Building on the premises of the resource-based view and signalling theory, the study is contextualized in the fashion industry as its current production levels require a significant consumption of natural resources, particularly water. Results show that, while the publication of the water footprint may damage companies’ reputations, initiatives aimed at increasing transparency and reducing environmental impact can reverse these losses to a large extent. In this sense, the study advances the idea that, despite possibly presenting undesirable consequences at first, the adoption of natural capital accounting can be beneficial to firms later on, with reputational gains representing important strategic incentives. Further research in different countries and industries will be beneficial to assess the possible context impact on our results.

Leaf and soil nutritional composition of purple passion fruit (Passiflora edulis Sims) as influenced by organic nutrients amended with biofertilizer consortium

The use of organic nutrient regimes is regarded as holistic and ecological approach for agricultural sustainability. It offers improved soil health, increased crop growth and enhanced fruit quality, whilst minimizing costs and sustaining the use of natural resources. The present investigation was conducted over two consecutive seasons, viz. 2021–22 and 2022–23 at Mizoram University, Aizawl, India to study the effect of different combinations of organic manures along with consortium of biofertilizers on leaf and soil characteristics of purple passion fruit (Passiflora edulis Sims). The investigation comprises of fourteen treatments of various combinations of organic manures along with consortium of biofertilizers, viz. farmyard Manure (FYM) vermicompost (VC) pig manure (PIM), poultry manure (POM), Azospirillum, phosphate solubilizing bacteria (PSB), potash solubilizing bacteria (KSB), and vesicular arbascular mycorrhiza (VAM). The results demonstrated that the use of organic amendments in combination with biofertilizers enhanced leaf nutrient status as well soil properties in the passion fruit orchard. Among the different treatment combinations used in the investigation, POM + Azospirillum + PSB + KSB + VAM was the most efficient in improving the leaf and soil nutrient status of passion fruit. This consortium may achieve high microbial load, high nutrient availability for soil which results in better growth of the crop. This treatment may therefore be recommended as an alternative option to meet the demand for long term maintenance of soil fertility as well agro-ecosystem conservation and sustainability.

A Sustainable Future : The Importance and the Development of Sustainable Finance In the 21st Century

The environmental problems that have emerged along with rapidly increasing global warming in recent years have made the concept of sustainability an important issue in the world in general. This fact has been largely effective in increasing the sensitivity of businesses and leading corporations to the environmental problems. This situation has led businesses to implement environmental friendly policies and invest in these areas, both interms of efficient use of natural resources and minimizing the damage to the environment. With the increasing global warming, climate change has recently become one of the most important problems in the world, and many countries have started to make efforts to reduce the risk of climate change. The inadequacy of environemental measures taken so far has necessitated the search for solutions in different areas regarding this issue. In this sense, financial institutions also contribute to climate awareness by following environmental policies in their activities and developing products that prioritize the environment. The concept of sustainable finance has led to the development of various financial products and to the development of financing projects aimed at protecting the environment. While the concept of sustainable finance is perceived as the responsibility of public authorities, the private sector has also been included in the process with the Sustainable Development Goals in the UN 2030 Agenda. There is no doubt that sustainable banking and finance practices, especially the implementation of sustainability practices by banks and other corporations in developing countries will contribute to the development of these countries considerably. In this study, it is aimed to draw attention to the global climate crisis, to emphasize the relationship between finance and the environment, and to contribute to the increase of applications in this field in the world by introducing green financing tools. One of the important functions of sustainable finance against the climate crisis is the evolution of companies funded within the scope of ESG criteria into a production process that tends to be sensitive to carbon emissions, as well as acquiring social and governance sensitivity. In this way, an economic process can be carried out on the axis of environmental and social awareness. In addition to combating climate change, it can be an important supporter in achieving the Sustainable Development Goals.

The prohibition against environmental damage and waste of resources is very relevant to modern environmental challenges such as deforestation, pollution, and climate change. This study highlights the importance of wise water management, preservation of flora and fauna, and environmental education as part of the responsibility of mankind. Tafsir Al-Misbah emphasizes that the use of natural resources must be carried out fairly and in balance to ensure the sustainability of nature for future generations. The research method used is a descriptive analytical library study with primary data sourced from the verses of the Qur'an in Tafsir Al-Misbah by M. Quraish Shihab. The research concludes that Islamic teachings on natural resource management, as outlined in Tafsir Al-Misbah, provide strong moral and ethical guidance for addressing current environmental issues. By emphasizing the principles of justice and balance, these teachings support global efforts to achieve environmental sustainability and long-term well-being.

Optimalisasi Sumber Daya Alam untuk Meningkatkan Ekonomi Kota Medan

This research aims to evaluate the use of Medan City's natural potential as the main driver of the economy. As a country that has abundant natural wealth, Medan has a great opportunity to direct economic growth in a more advanced and sustainable direction. Through a qualitative approach, this research explores various literature sources, including data from BPS, scientific journals, and other related literature. These findings highlight that although various programs and policies have been implemented, optimal use of natural resources in Medan, especially in the Fisherman's Village area, is still far from expectations. This fact is reflected in the low income of traditional fishing communities which only reaches around Rp. 1,429,551 per month. Therefore, this research emphasizes the need for more effective strategies in managing natural resources so that they can have a significant positive impact on the economy in Medan City.

ВОДНІ, ПРИБЕРЕЖНО-ВОДНІ ТА ЗАПЛАВНІ БІОТОПИ ТЕРИТОРІЇ РЛП «ЯЛІВЩИНА», ЇХ ВИДОВА РІЗНОМАНІТНІСТЬ ТА ЕКОЛОГО-ЦЕНОТИЧНІ ОСОБЛИВОСТІ

The article is devoted to the study of aquatic, coastal, and floodplain habitats within the territory of the RLP “Yalivshchyna”. It analyzes the species diversity of these habitats and provides data on the classification of biotopes in the RLP “Yalivshchyna”. A preliminary classification scheme, based on the results of original research and some bibliographic data, is presented. The analysis has revealed a significant diversity of aquatic ecosystems in the RLP “Yalivshchyna”, indicating the ecological stability and azonality of these systems within the park. The aquatic, coastal, and floodplain habitats within the study area are characterized by seven main categories (types), which exhibit significant floristic diversity, including 130 species of vascular plants belonging to 78 genera and 41 families. A notable feature of the studied habitats is the presence of a wide-ranging flora of most species due to their influence on water and floodplain systems. This results in the predominance of species characteristic of the Holarctic and Euro-Asian regions. From an ecological perspective, the biotopes of the Stryzhen River within the territory of the RLP “Yalivshchyna” are significantly represented by vascular plant species from limnophytic groups, and marsh and hygrophilic florogenetic complexes. This diversity is influenced by the overregulation of the Stryzhen riverbed, slow flow, and the formation of bottom sediments of varying thicknesses. The aquatic, coastal, and floodplain vegetation of the Stryzhen River is characterized by the presence of monodominant communities typical for this region, which exhibit limited species diversity, similar composition and structure of coenoses, and the influence of adventive species. An inventory of habitats in the channel and floodplain parts of the Stryzhen River was carried out, allowing for an assessment of the natural environment in accordance with modern approaches. The data obtained on these habitats allows for the determination of their hierarchical structure and identification of the stability level of each habitat. This, in turn, will facilitate the development of appropriate conservation strategies for these habitats in the future and can be used to maintain and preserve aquatic ecosystems, ensure the balanced use of natural resources, and support the sustainable development of the RLP “Yalivshchyna”.

Algerian Artemisia herba-alba (Asso): Extract and Essential Oils Investigation

Background/Objective: Numerous studies have demonstrated the ethno-and pharmacological properties of various Artemisia species. However, this plant genus which grows abundantly and wildly in the ‘Tébessa’ Algerian region has not been investigated. This study focuses on the phytochemical characterization, biological activities evaluation with the antibacterial fraction identification of the aerial part aqueous extract (AE) and essential oil (EO) from Algerian Artemisia herba alba ( Aha) growing wild in the ‘Tebessa' region. Methods: Polyphenols, flavonoids, and condensed tannins were analyzed by spectrophotometer and the antimicrobial activity was determined by the gel diffusion followed by micro-dilution methods. The antioxidant effect was assayed using 2,2-diphenyl-1-picrilhidrazil (DPPH), total antioxidant capacity (TAC), and ferric reducing power (FRAP) tests. The cytotoxic and anti-leishmaniasis activities were experienced on Raw 264.7 cell line and on L. infantum and L. major promastigotes respectively. Thin-layer chromatography (TLC)/autobiography and gas chromatography-mass spectrometry (GC-MS) techniques were used to isolate and identify the antibacterial compounds. EO profile was determined by GC-MS analysis. Results: The extracts (AE and EO) demonstrated antioxidant activity, with the AE exhibiting the most pronounced levels. Both extracts showed antimicrobial activity against all the strains tested however; the EO effect was more effective, especially against the E. feacalis strain with a minimum inhibitory concentration (MIC) value of 0.0625 mg/mL. The antibacterial fraction exerted by AE towards E. feacalis was identified. AE and EO extracts showed antileishmanial activity and no toxic effect however, volatile extract was the most effective. EO profile revealed 19 identified compounds, led by camphor (51.14%), followed by 1,8 Cineole (19.30%), camphene (6.90%) and chrysanthenone (5.68%). Conclusion: As a result, the both extracts promise a high potential applications in agri-food, pharmaceutical, cosmetic sectors. This study aligns with Sustainable Development Goals (SDGs) 3, 12, and 15, emphasizing potential health benefits, the responsible use of natural resources, and biodiversity conservation.
