Chemical composition, Biological Activities and In Silico Evaluation of Essential Oils from the aerial, and root parts of Nepeta hindostana (B. Heyne ex Roth)-Haines Grown in North India

Nepeta hindostana, commonly known as the North Indian Catmint, is an important Indian aromatic and medicinal plant of family Lamiaceae. Its leaves are extensively used as cardiac tonic and gargle to cure sore throat in the form of extract or decoction. However, there are few reports on the chemical composition and biological activities of leaf essential oil, while the root essential oil has not yet been explored. In this context, the present study is aimed to characterize the chemical composition and to evaluate different biological activities of the essential oil (EO) from aerial and root part of the plant. Thus, the EOs were hydro-distilled from aerial parts (stem, leaf, flower) and roots of the plant and analyzed by GC-MS. Twenty-four and thirty-four compounds, contributing 95.5% and 90.7% of the total oil composition, were identified in aerial and root EOs, respectively. Both the oils appeared to be antioxidant via in-vitro methods. Aerial and root EOs showed albumin denaturation activity with relative IC50 values of 20.46 ± 0.21 μg/mL and 31.79 ± 0.28 μg/mL. Root EO exhibited higher α-amylase inhibition activity (IC50 = 10.86 ± 0.45 μg/mL) than aerial part EO (IC50 = 25.33 ± 0.24 μg/mL). Both the EOs exerted a prominent antifeedant activity against Spilosoma obliqua. The bioactivity of the main identified compounds in the EOs were predicted using PASS (prediction of activity spectra for substances) tools. Furthermore, molecular docking studies highlighted that β-sitosterol had the most efficient binding affinity with NADPH oxidase and alpha-amylase receptors.

Chemical Profile and Biological Activities of Essential Oil from Piper arboreum for Development and Improvement of Mouthwash.

Studies show that more consumers are using natural health products in the modern world. We have noticed a growing demand in markets and the professional community for mouthwashes that contain natural compounds. The objective of this study was to assess the chemical characterization and microbiological potential of the essential oil Piper arboreum (EOPa) to provide data to enable the development of a low-cost mouthwash. The evaluation of the antibacterial and bacterial resistance modulating activity was performed by the microdilution method to determine the minimum inhibitory concentration. The chemical components were characterized by gas chromatography coupled with mass spectrometry, which identified 20 chemical constituents, with caryophyllene oxide being one of the major compounds. The EOPa showed an MIC ≥ 1024 µg/mL for all bacterial strains used in the tests. When evaluating the modulating activity of EOPa combined with chlorhexidine, mouthwash and antibiotics against the bacterial resistance, the oil limited synergistic activity between the MIC of the products tested in combination (37% to 87.5%). Therefore, we recommend expanding the tests with greater variation in the EOPa concentration and the products used, as well as toxicity assessments and in vivo testing, with the purpose of the development of a possible low-cost mouthwash base that is accessible to the most vulnerable populations.

Acute toxicity and anti-inflammatory activity of essential oils of Cotula cinerea from southwest Algeria

This work deals with the biological activity of the essential oils of an Algerian plant (Cotula cinerea) which belongs to the Asteraceae family. The study was carried out in the south-west of Algeria. We chose essential oils which are natural substances thanks to their numerous anti-infectious, antioxidant and antibacterial properties, etc. The objective of this work is to study the acute toxicity as well as the evaluation of the anti-inflammatory properties of the essential oils of both organs (leaves and flowers) of Cotula cinerea. As methodological approaches, we used the hydrodistillation technique to obtain the essential oils from leaves and flowers. Thus, the acute toxicity was determined by Lorke's method and the anti-inflammatory activity was evaluated by measuring the plantar oedema of mice induced by carrageenan. The results show that the essential oil extracts of the leaves and flowers are low toxic substances with LD50s of 1131.37 mg/kg and 1264.91 mg/kg respectively. They also show a considerable anti-inflammatory effect at doses not exceeding 300 mg/kg with maximum percentages of 86.16% for leaves and 80.87% for flowers. These results show the efficacy of the essential oils of this plant and their therapeutic richness which can be used in traditional medicine for anti-inflammatory treatment. This study has provided additional knowledge on the biological activity of Cotula cinerea essential oils and has opened perspectives for the research of the active principles contained in this species as well as the application of biotechnology to know the molecular mechanism and valorise this natural wealth.

Polymer-Based Hydrogels Enriched with Essential Oils: A Promising Approach for the Treatment of Infected Wounds.

Among the factors that delay the wound healing process in chronic wounds, bacterial infections are a common cause of acute wounds becoming chronic. Various therapeutic agents, such as antibiotics, metallic nanoparticles, and essential oils have been employed to treat infected wounds and also prevent the wounds from bacterial invasion. Essential oils are promising therapeutic agents with excellent wound healing, anti-inflammatory and antimicrobial activities, and good soothing effects. Some essential oils become chemically unstable when exposed to light, heat, oxygen, and moisture. The stability and biological activity of essential oil can be preserved via loading into hydrogels. The polymer-based hydrogels loaded with bioactive agents are regarded as ideal wound dressings with unique features, such as controlled and sustained drug release mechanisms, good antibacterial activity, non-toxicity, excellent cytocompatibility, good porosity, moderate water vapour transmission rate, etc. This review addresses the pre-clinical outcomes of hydrogels loaded with essential oils in the treatment of infected wounds.

Chemical composition and biological activity of essential oil of the Moroccan endemic Origanum grosii

The aim of this research was to study the chemical composition and biological activity of essential oil of the Moroccan endemic Origanum grosii on biofilm of Staphylococcus aureus strains.Qualitative and quantitative composition of the essential oil was analyzed by gas chromatography and gas chromatography-mass spectrometry. The Minimum Inhibitory Concentration was determined using the broth microdilution method.Phytochemical analyses revealed a high content of carvacrol, p-cymene, γ-terpinene and thymol. The antibiofilm effect of essential oil of Origanum grosii was tested against three staphylococcal strains (Staphylococcus aureus MBLA, Staphylococcus aureus CECT976 and Staphylococcus aureus ATCC25923). Results showed that the Minimum Inhibitory Concentration are lower than the Minimum Bactericidal Concentration (MBC = 2 MIC), hence the bacteriostatic power of this essential oil.In fact, essential oil of Origanum grosii presented a high antibiofilm effect against different staphylococcal strains by the inhibition of the biofilm formation and showed also a significant antibacterial activity (dose-dependent), since it increases with the increase in the concentration of this essential oil.The use of essential oil of Origanum grosii as natural antibacterial agent may effectively inhibit the growth of biofilm of medical relevance. Results indicated also that essential oil of Origanum grosii may be a potential alternative against Staphylococcus resistant strains.For this reason, the essential oil of Origanum grosii can be a promising alternative for both microbial control and therapeutic treatment against pathogenic resistant bacteria. Nevertheless, further studies should be conducted in order to elucidate the mechanisms of action of the essential oil on the bacterial cells under study.

Preliminary Study on Phytochemical Constituents and Biological Activities of Essential Oil from Myriactis nepalensis Less.

In response to the need for novel therapeutic strategies to combat the development of microbial resistance, plant essential oils may represent a promising alternative source. This study set out to characterize the chemical composition and assess the antibacterial potential of Myriactis nepalensis Less. essential oil (MNEO). Essential oil isolated from M. nepalensis by hydrodistillation was analyzed using a GC–MS technique. The antibacterial properties of MNEO alone and combined with antibiotics (chloramphenicol and streptomycin) were tested via the disc diffusion, microbroth dilution, and checkerboard methods. MNEO was represented by oxygenated sesquiterpenes (60.3%) and sesquiterpene hydrocarbons (28.6%), with caryophyllene oxide, spathulenol, humulene epoxide II, β-elemene, neointermedeol, and β-caryophyllene as the main compounds. MNEO exhibited a strong antibacterial effect against Gram-positive bacteria, with MIC and MBC values of 0.039 mg/mL and 0.039–0.156 mg/mL, respectively, and synergistic effects were observed in both combinations with chloramphenicol and streptomycin. Furthermore, the antibiofilm and cytotoxic activities of MNEO were also evaluated. The crystal violet assay was used for quantification of Staphylococcus aureus biofilm formation, and an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay was conducted to determine cell viability. The results revealed MNEO could dose-dependently inhibit Staphylococcus aureus biofilm formation and possessed potential cytotoxic on both normal and cancer cells (IC50 values from 13.13 ± 1.90 to 35.22 ± 8.36 μg/mL). Overall, the results indicate that MNEO may have promising applications in the field of bacterial infections.

Seasonal variation in the essential oil composition and biological activities of Thymus linearis Benth. Collected from the Kumaun region of Uttarakhand, India

This research assessed the seasonal variation in the chemical composition and biological activities of essential oils extracted from Thymus linearis Benth. in rainy season and winter season. The essential oil highest yield was recorded in the rainy season. The oils were analyzed by GC and GC-MS. Thymol was the marker component in both oils with varying compositions, i.e., 31.9% in rainy season oil and 35.7% in winter season oil. While assessing the biological activities, the antioxidant activity of the oils was investigated in vitro using three assays: DPPH radical scavenging activity, H2O2 radical scavenging activity and metal chelating activity. The highest antioxidant capacity was observed in oil extracted in winter season. Winter season oil showed good inhibition of protein denaturation (IC50 = 26.55 ± 0.03 μg/mL) as compared to the rainy season oil. The oils inhibited the activity of α-amylase with IC50 of 32.27 ± 0.05 μg/mL (winter) and IC50 of 32.87 ± 0.04 μg/mL (rainy). Insect antifeedant activity performed using the leaf dip method against Spodoptera litura afforded significant results with slight variations. Essential oils were also tested against Meloidogyne incognita for nematicidal activity and inhibition of eggs hatching potential in laboratory conditions. Moreover, it was found that activity level of oils was seasonal dependent. The pharmacological activities of the major components were also predicted using the web-based software Pass.

Chemical constituents of essential oil extracted from Rhododendron anthopogonoides and its bioactivities against Tribolium castaneum and Ditylenchus destructor

Essential oils (EOs) extracted from botanical resources have greatly been appraised as insecticides against a broad spectrum of pre- and postharvest pests and pathogens. This study aimed to investigate the chemical constituents of the EO from Rhododendron anthopogonoides and the biological activity of EO and its main compound against Tribolium castaneum and Ditylenchus destructor. A total of 14 compounds were identified, and the main components of EO from R. anthopogonoides were 4-phenyl-2-butanone (47.73%), eudesma-3,7(11)-diene (14.52%), curzerene (9.5%), 4-phenylbutan-2-ylacetate (6.43%), β-cadinene (5.79%), and germacrone (5.73%). The results of bioassays indicated that the EO oil of R. anthopogonoides possessed obvious contact activity (LD50 = 9.83 μg/adult) and repellent activity against T. castaneum. The indoor toxicity indicated that the R. anthopogonoides EO and its main constituent 4-phenyl-2-butanone possessed strong nematicidal activity against D. destructor (LC50 = 0.21 and 0.04 mg/mL). These results provided the theoretical basis for controlling T. castaneum and D. destructor using the EO from R. anthopogonoides.

Hydro-Distilled and Supercritical Fluid Extraction ofEucalyptus camaldulensisEssential Oil: Characterization of Bioactives Along With Antioxidant, Antimicrobial and Antibiofilm Activities.

Present research work evaluates variation in volatile chemicals profile and biological activities of essential oil (EO) obtained from the leaves of eucalyptus (Eucalyptus camaldulensis Dehnh.) using hydro-distillation (HD) and supercritical fluid extraction (SFE). The yield (1.32%) of volatile oil by HD was higher than the yield (.52%) of the SFE method (P < .05). The results of physical factors like density, color, refractive index, and solubility of the EOs produced by both the methods showed insignificant variations. Gas chromatography - mass spectrometry (GC-MS) compositional analysis showed that eucalyptol (31.10% and 30.43%) and α-pinene (11.02% and 10.35%) were the main constituents detected in SFE and HD extracted Eucalyptus camaldulensis EO, respectively. Antioxidant activity-related parameters, such as reducing ability and DPPH free radical scavenging capability exhibited by EO obtained via SFE were noted to be better than hydro-distilled EO. Supercritical fluid extracted and hydro-distilled essential oils demonstrated a considerable but variable antimicrobial potential against selected bacterial and fungal strains. Interestingly, oil extracted by SFE showed relatively higher hemolytic activity and biofilm inhibition potential. The variation in biological activities of tested EOs can be linked to the difference in the volatile bioactives composition due to different isolation techniques. In conclusion, the EO obtained from Eucalyptus leaves by the SFE method can be explored as a potential antioxidant and antimicrobial agent in the functional food and nutra-pharmaceutical sector.

Unprecedented nanoemulsion formulations (NE) of Jasminum humile and Jasminum grandiflorum essential oils (EO) were prepared, and examined for their cytotoxic and antiviral activities. NE characterization and stability examination tests were performed to ensure formula stability. The antiviral activity was determined against hepatitis A (HAV) and herpes simplex type-1 (HSV-1) viruses using MTT assay, while the cytotoxic potential was determined against liver (HepG-2), breast (MCF-7), leukemia (THP-1) cancer cell lines and normal Vero cells. Statistical significance was determined in comparison with doxorubicin as cytotoxic and acyclovir as antiviral standard drugs. GC-MS analysis indicated twenty four compounds in the EO of J. humile and seventeen compounds in the EO of J. grandiflorum. Biological investigations of pure EOs revealed weak cytotoxic and antiviral effects. Nevertheless, their NE formulations exhibited high biological value as cytotoxic and antiviral agents. NE formulations also showed feasible selectivity index for the viral-infected and cancer cells (especially HepG-2) than normal Vero cells. Both nanoemulsions showed lower IC50 than standard doxorubicin against HepG-2 (26.65 and 22.58 vs. 33.96 μg/mL) and MCF-7 (36.09 and 36.19 vs. 52.73 μg/mL), respectively. The study results showed the dramatic effect of nanoemulsion preparation on the biological activity of EOs and other liposoluble phytopharmaceuticals.

Phytochemical constitutes and biological activities of essential oil extracted from irradiated caraway seeds (Carum carvi L.)

Purpose Essential oils (EOs) obtained from spices, herbs, and medicinal plants are well known in traditional medicine and are an area of interest due to their various biological activities. Therefore, the present study investigates the chemical composition, phytochemical properties, as well as the biological activity of EOs, recovered from un-irradiated and irradiated (2.5, 5, and 10 kGy) caraway seeds. Materials and methods Carum carvi L. seeds were irradiated with gamma irradiation at dose levels 2.5, 5, and 10 kGy, then EOs were recovered from all the samples. The chemical composition, phenols, and flavonoids content were evaluated. As well, antimicrobial and antitumor activities against the two cell lines [colorectal adenocarcinoma (Caco-2) and liver cancer (HepG-2)] were investigated. Results The results indicated the percentage of oil increased by radiation, especially a dose of 10 kGy, which gave the highest percentage (3.50%) compared to the control. Also, the Gas Chromatography/Mass Spectrometry (GC-MS) analysis revealed the presence of 26 compounds in the essential oil extracts. The main constituent of caraway seeds EOs was Carvone followed by Limonene. According to the results, there was an increase in the content of phenols and flavonoids by using gamma rays compared with control, the maximum increase was observed at dose level 10 kGy (13.70 and 7.38 mg/g oil, respectively) followed by 5 kGy (11.20 and 5.86 mg/g oil, respectively). The antioxidant properties of the caraway essential oils were increased by increasing the irradiation dose level (2.5–10 kGy) analyzed by DPPH radical and metal chelating activity. Caraway essential oils have an antimicrobial action against Gram-positive and Gram-negative bacteria as well as fungi. The antimicrobial activity was increased as the irradiation dose was raised and the10 kGy dose was more effective in suppressing the growth of bacteria and fungi. Additionally, the caraway essential oils have anticancer activity against the two cell lines studied; colorectal adenocarcinoma (Caco-2) and liver cancer cell line (HepG-2) as reduced the cell viability and density. Conclusion The 10 kGy dose was more effective for oil yield, phenols, flavonoids, and antioxidant activity as well as antibacterial and antifungal activities. Furthermore, the caraway essential oils indicated anticancer activity against the two cell lines studied; colorectal adenocarcinoma (Caco-2) and liver cancer cell line (HepG-2) as reduced the cell viability and density. So caraway could be considered an important herb with multiple therapeutic uses.
