Nanoformulations containing rosemary oil for gray mold control in strawberries

Gray mold, caused by Botrytis cinerea, affects strawberry crops (Fragaria x ananassa) and can cause major losses. Managing the disease with fungicides can harm health and the environment and can lead to the selection of pathogens resistant to their active ingredients. The use of essential oils (EOs) represents an alternative control method due to their richness in antimicrobial compounds, such as rosemary EO (Rosmarinus officinalis). However, the high volatility of several components of these oils makes commercial use difficult, and nanoencapsulation presents a technology to increase stability. In the present study, three formulations containing rosemary EO—nanoemulsion (NE), nanostructured lipid carrier (NLC), and nanocapsules with chitosan (NC)—were evaluated on strawberry fruits and against the fungus. The nanoformulations retained their characteristics (mean values: size 142 nm; polydispersity index 0.131; pH 4.99; zeta potential -20.2 mV for NE and NLC, and 19.1 mV for NC) when stored at 40 °C for 60 days. All nanoformulations had a direct effect on spore germination and mycelial growth of B. cinerea, possibly due to damage caused to the cell wall and plasma membrane, and changes in the pathogen's oxidative balance. NE containing 2 % EO, when applied by immersion, reduced the incidence and severity of the disease by around 40 % and 70 %, respectively, 6 days after treatment. The fruits treated with this formulation maintained their physicochemical characteristics for longer. Thus, the use of rosemary oil from NE can be an option for managing gray mold and increasing the shelf life of the fruits.

Green synthesis and antimicrobial evaluation of Ag/TiO2 and Ag/SeO2 Core-Shell nanocomposites using r. Officinalis extract: A combined experimental and docking study

The escalating threat of antibiotic resistance necessitates the development of novel, sustainable antibacterial agents. This study investigates the potential of utilizing Rosmarinus officinalis leaf extracts to synthesize Ag/TiO2 and Ag/SeO2 nanocomposites. R. officinalis extract, a rich source of phenolic and flavonoid compounds, effectively and safely acts as a reducing and capping agent for the green synthesis of Ag/TiO2 and Ag/SeO2 nanocomposites. Characterization of nanocomposites revealed the nanoparticles’ nanoscale size, ranging from 43.34 to 96.58 nm for Ag/TiO2 and 8.04 to 21.72 nm for Ag/SeO2. Both types of nanoparticles exhibited a spherical morphology and distinct crystalline structure. The nanoparticles demonstrated significant antibacterial properties against multiple bacterial strains. The effective concentration for antibacterial activity was determined to be 30.99 mg/mL for Ag-TiO2 and 32.41 mg/mL for Ag-SeO2 nanoparticles. The surface charge of the nanoparticles was measured to be −14.0 mV for Ag-TiO2 and −15.4 mV for Ag/SeO2. Molecular docking simulations investigated the interactions between rosmarinic acid, its derivatives, and the antibiotic cefotaxime with a bacterial protein (e.g., DNA gyrase). These simulations provided insights into the distinct antibacterial mechanisms of these compounds. Briefly, this research highlights the potential of R. officinalis-derived nanocomposites as promising antibacterial agents. The eco-friendly synthesis and promising results pave the way for their development and application in medicine, biochemistry, and environmental fields.

Spider web-reinforced chitosan/starch biopolymer for active biodegradable food packaging

In this study, starch (ST), chitosan (CH), spider silk (SW), and their hybrid composite bioplastics were fabricated and examined for physicochemical and mechanical properties. The essential oils (EOs) of Rosmarinus officinalis were encapsulated to enhance their biological application. The prepared composite films were characterized using various spectroscopic techniques such as XRD, SEM, GCMS–, UV–VIS, TGA, and FTIR spectroscopy. The antimicrobial activity of the prepared film was tested against S. aureus bacterial and C. albican fungal strains which showed a greater zone of inhibition for the composite film encapsulated with EOs. The biodegradability of the synthesized film was evaluated for 60 days in soil under laboratory conditions. The composite film containing spider web and essential oil significantly improved mechanical properties. The physicochemical results, such as moisture, solubility, swelling, transmittance, opacity, and water vapor permeability, of the prepared bioplastic were comparable with those of the control plastic. The EO-based film had greater antioxidant activity against DPPH, hydrogen peroxide, and phosphomolybdenum assays, with an inhibition range of 60–70 %. The addition of spider web and essential oil to the chitosan/ starch film significantly increased the shelf life of injera and tomatoes for 7 and 10 days, respectively for the EO-based film. The biodegradability of the synthesized film has shown a great reduction in the weight and growth of microorganisms. In general, the CH/ST/SW and CH/ST/SW/EOs composite films have greater mechanical, biological, physicochemical, and potential improvement of food shelf life applied as either coating or packaging material.

Growth, Biochemical Traits, Antioxidant Enzymes, and Essential Oils of Four Aromatic and Medicinal Plants Cultivated in Phosphate-Mine Residues.

Revegetation emerges as a promising approach to alleviate the adverse impacts of mining residues. However, it is essential to evaluate the characteristics of these materials and select suitable plant species to ensure successful ecosystem restoration. This study aimed to investigate the effects of phosphate-mine residues (MR) on the growth, biochemical properties, and essential oil concentration of Rosmarinus officinalis L., Salvia Officinalis L., Lavandula dentata L., and Origanum majorana L. The results showed that R. officinalis L. appeared to be particularly well-suited to thriving in MR soil. Our finding also revealed that L. dentata L., O. majorana L., and S. officinalis L. grown in MR exhibited significantly lower growth performance (lower shoot length, smaller leaves, and altered root structure) and higher antioxidant activities, with an alterations of photosynthetic pigment composition. They showed a decrease in total chlorophylls when grown on MR (0.295, 0.453, and 0.562 mg g-1 FW, respectively) compared to the control (0.465, 0.807, and 0.808 mg g-1 FW, respectively); however, they produced higher essential oil content (1.8%, 3.06%, and 2.88%, respectively). The outcomes of this study could offer valuable insights for the advancement of revegetation technologies and the utilization of plant products derived from phosphate-mine residues.

GC-MS, FTIR analysis and effects of thyme (Thymbra capitata L. Cav) and rosemary (Rosmarinus officinalis L.) essential oils on the growth and pathogenicity of Botrytis fabae

ABSTRACT This study examined the efficacy of rosemary (Rosmarinus officinalis L.) and thyme (Thymbra capitata L. Cav) essential oils (EOs) in Botrytis fabae management. The key compounds identified in thyme EO were carvacrol (48.13%), 4-Methoxystyrene (17.32%), and cyclohexene (12.37%), whereas the rosemary EO contained α-pinene (55.08%), camphene (10.52%), and d-limonene (7.86%). In vitro tests showed that thyme EO was more effective than rosemary, achieving total inhibition of B. fabae at a concentration of 50 µL compared to 250 µL for rosemary EO. Molecular docking indicated that the primary compounds in each EO interacted with 14 alpha-sterol demethylase. Greenhouse tests confirmed that both EOs significantly reduced disease severity without phytotoxicity. These findings suggest that thyme and rosemary EOs could be effective in B. fabae management, thereby promoting eco-friendly agriculture.

Extraction and chemical constituents of the essential oils from Rosmarinus officinalis L. and Corymbia citriodora

The essential oils of Rosmarinus officinalis L. and Corymbia citriodora (Hook.) K.D.Hill & L.A.S.Johnson leaves have chemical constituents with fungicide potential. The objective of this work was to determine the yield and the main chemical compounds of the essential oils of these species. Plants of the two species were georeferenced and collected in municipalities of Rio Grande do Sul, and identified in the Botany Laboratory of UNIJUÍ. The essential oils were extracted by hydrodistillation and the yield was based on fresh vegetable mass. The analyses of the chemical constituents were determined by CG-MS. A yield of 0.49% was obtained for R. officinalis and of 1.54% for C. citriodora. Similar to other studies, the major constituents of rosemary essential oil were camphor, 1,8-cineol, canfene and α-pineno, and the ones of eucalyptus essential oil were citronelal, isopulegol and citronelol. It is concluded that the chemical constituents are similar to those reported in the literature and the essential oil yield of the species is low and dependent on external conditions.

Effect of Different Porous Size of Porous Inorganic Fillers on the Encapsulation of Rosemary Essential Oil for PLA-Based Active Packaging.

Essential oils are interesting active additives for packaging manufacturing as they can provide the final material with active functionalities. However, they are frequently volatile compounds and can be degraded during plastic processing. In this work Rosmarinus officinalis (RO) essential oil was encapsulated into Diatomaceous earth (DE) microparticles and into Halloysite nanotubes (HNTs) and further used to produce eco-friendly active packaging based on polylactic acid (PLA). PLA-based composites and nanocoposites films based on PLA reinforced with DE + RO and HNTs + RO, respectively, were developed by melt extrusion followed by cast-film, simulating the industrial processing conditions. As these materials are intended as active food packaging films, the obtained materials were fully characterized in terms of their mechanical, thermal and structural properties, while migration of antioxidant RO was also assessed as well as the compostability at laboratory scale level. Both DE and HNTs were able to protect the Rosmarinus officinalis (RO) from thermal degradation during processing, allowing to obtain films with antioxidant properties as demonstrated by the antioxidant assays after the materials were exposed for 10 days to a fatty food simulant. The results showed that incorporating Rosmarinus officinalis encapsulated in either DE or HNTs and the good dispersion of such particles into the PLA matrix strengthened its mechanical performance and sped up the disintegration under composting conditions of PLA, while allowing to obtain films with antioxidant properties of interest as antioxidant active food packaging materials.

Polyphenols Investigation and Antioxidant and Anticholinesterase Activities of Rosmarinus officinalis L. Species from Southwest Romania Flora.

Rosemary is one of the most important medicinal plants for natural therapy due to its multiple pharmacological properties, such as antioxidant, anti-inflammatory, neuroprotective, antiproliferative, antitumor, hepato- and nephroprotective, hypolipidemic, hypocholesterolemic, antihypertensive, anti-ischemic, hypoglycemic, radioprotective, antimicrobial, antiviral, antiallergic, and wound healing properties. Our study reports for the first time, over a 12-month period, the identification and quantification of polyphenols and the investigation of the antioxidant and acetylcholinesterase (AChE) inhibitory activities of the Rosmarinus officinalis L. species harvested at flowering from the flora of southwestern Romania (Oltenia Region). Identification and quantification of polyphenolic acids was made by ultra-high-performance liquid chromatography/mass spectrometry (UHPLC/MS). Total phenolic content was determined using the spectrophotometric method. In situ antioxidant and anticholinesterase activities were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and AChE inhibitory assay, respectively, on high-performance thin-layer chromatography (HPTLC) plates. DPPH radical scavenging activity was also assessed spectrophotometrically. The results revealed significant correlations between specific polyphenolic compounds and the measured biological activities, understanding the role of seasonal variations and providing insights into the optimal harvesting times and medicinal benefits of rosemary. Our research brings new information on the phytochemical profile of R. officinalis as a natural source of polyphenols with antioxidant and AChE inhibitory properties.

Nail Lacquer Containing Origanum vulgare and Rosmarinus officinalis Essential Oils and Biogenic Silver Nanoparticles for Onychomycosis: Development, Characterization, and Evaluation of Antifungal Efficacy.

Onychomycosis is a common fungal nail infection for which new antifungals are needed to overcome antimicrobial resistance and the limitations of conventional treatments. This study reports the development of antifungal nail lacquers containing oregano essential oil (OEO), rosemary essential oil (REO), and biogenic silver nanoparticles (bioAgNPs). The formulations (F) were tested against dermatophytes using agar diffusion, ex vivo nail infection, and scanning electron microscopy techniques. They were evaluated for their pharmacotechnical characteristics and by FTIR-PAS to assess permeation across the nail. F-OEO and F-OEO/bioAgNPs were promising candidates for the final nail lacquer formulation, as they permeated through the nail and showed antifungal efficacy against dermatophytes-contaminated nails after 5 days of treatment. Treated nails exhibited decreased hyphae and spores compared to the untreated control; the hyphae were atypically flattened, indicating loss of cytoplasmic content due to damage to the cytoplasmic membrane. The formulations were stable after centrifugation and thermal stress, maintaining organoleptic and physicochemical characteristics. Both F-OEO and F-OEO/bioAgNPs had pH compatible with the nail and drying times (59-90 s) within the reference for nail lacquer. For the first time, OEO and bioAgNPs were incorporated into nail lacquer, resulting in a natural and nanotechnological product for onychomycosis that could combat microbial resistance.

Bioassay guided isolation and compounds identification of the anti-diabetic fractions of (rosemary) Rosmarinus officinalis leaves extract

BackgroundDiabetes mellitus is a metabolic disease characterized by prolonged elevated blood glucose levels. It is a common health problem with a high mortality and morbidity to the human race. A number of medicinal plants such as rosemary (Rosmarinus officinalis) have been used for the treatment of diabetes. Most of the anti-diabetic conventional drugs have been found to have some side effects and there is therefore need to explore new sources of anti-diabetic drugs. The aim of the current study was to investigate the possibility of getting anti-diabetic compounds from R. officinalis that can be used as leads for drug discovery.MethodologyR. officinalis leaves were macerated in 50% methanol in dichloromethane and the crude extract fractionated by column chromatography. The obtained fractions were subjected to an in-vitro alpha-amylase inhibition assay. The anti-hyperglycemic potential of the fractions was evaluated in diabetic induced Wistar rats. The most potent fractions were analyzed by gas chromatography-mass spectrophotometry (GC-MS) for identification of the compounds.ResultsA total of 21 chromatographic fractions were assembled with different alpha- amylase inhibition activity. Eleven of the fractions had more than 30% alpha-amylase inhibition activity. The ethyl acetate fraction had the highest inhibition potential (LC50 of 2.8 μg/mL). The anti-diabetic assay in rats showed that fractions (F1) and (F4) had highest blood glucose reduction of 44.5 ± 0.4 and 52.8 ± 1.3%, respectively (p < 0.05). GC-MS analysis of fractions F1 and F4 showed the presence of 21 and 23 compounds in F1 and 23, respectively.ConclusionThis study has demonstrated that R. officinalis crude extract fractions obtained from 50% methanol in dichloromethane possesses alpha-amylase inhibitory and anti-hyperglycemic activities as well as secondary metabolites with varying chemical structures. The hexane and hexane/ethyl acetate (8/2) fractions showed most potent alpha-amylase inhibition with high anti-hyperglycemic activity giving hope of a possibility of obtaining lead compounds for new anti-diabetic drugs.

Protective and Therapeutic Effects of Medicinal Plants Against Food Additive-Induced Toxicity.

For thousands of years, people have used medicinal plants and in many parts of the world, traditional medicines continue to play a significant role in the standard treatment of a wide range of illnesses. With changes in modern eating patterns, there has recently been an increase in the use of processed foods. Furthermore, the use of food additives has increased in tandem with the production of processed foods. The dosage levels used for these additives are determined using empirical analyses. However, some additives have demonstrated long-term toxic effects on the human body in toxicity tests. Plants are one of the main sources of biologically active substances and in recent years, many studies have focused on the health benefits of phytochemicals and plant-derived extracts in the treatment and prevention of food additive toxicity. This review clarified studies on several medicinal plants, such as &lt;i&gt;Physalis peruviana&lt;/i&gt; L., &lt;i&gt;Jatropha tanjorensis&lt;/i&gt;, &lt;i&gt;Cymbopogon citratus&lt;/i&gt;,&lt;i&gt; Ficus carica&lt;/i&gt;, &lt;i&gt;Rosmarinus officinalis&lt;/i&gt; L. and others. The findings presented here demonstrate these plants' efficiency and success in preventing and lowering the toxicity of food additives through antioxidant activity reducing oxidative stress, and reduction in renal and hepatic toxicity. Therefore, these plant extracts have a preventive and therapeutic effect in reducing toxicity and may be the best option for reducing the toxicity of food additives in the future. Moreover, additional research is required to confirm the biologically active components found in medicinal plants that are effective in reducing this toxicity.

Study to determine the efficacy and onset of Bonipar, a topical analgesic for the management of acute and chronic musculoskeletal pain

BackgroundOpioid abuse and mortality are ravaging American society, highlighting the need to find alternative effective analgesics with fewer side effects. FDA-approved topical analgesics, including non-steroidal anti-inflammatory drugs (NSAIDs), are commonly used to treat musculoskeletal pain but can cause adverse effects. Natural compounds, including essential oils, are potential therapeutic alternatives for managing musculoskeletal pain. If these compounds can provide comparable analgesia to FDA-approved products, it will increase the available options for people with pain, improving quality of life with minimal morbidity and mortality. ObjectiveThis study assesses the effectiveness and onset of action of Bonipar, a topical analgesic formulated with camphor, methyl salicylate, and oils of coconut, eucalyptus, nutmeg, and rosemary, in managing musculoskeletal pain compared to 1.5 % diclofenac solution, an FDA-approved topical non-steroidal anti-inflammatory drug. MethodsOne hundred sixty-four adult patients with localized musculoskeletal pain were randomly assigned to twice-daily applications of either Bonipar or Diclofenac for one week. The primary outcome measure was a 50 % reduction in pain after one week. Secondary outcomes included the change in pain from baseline and onset of action, defined as the first reduction in pain by 20 %. ResultsAll patients completed the initial pain assessment to determine the onset of action. One-week data was available for 74 patients treated with diclofenac and 72 patients treated with Bonipar. Data for 18 patients were incomplete. The proportion of patients achieving a 50 % reduction in pain was statistically similar between the two groups. The success rates of achieving a 50 % pain reduction with Bonipar were found to be non-inferior to those treated with diclofenac. All follow-up time points showed roughly similar results between the groups. Regression models adjusted for age and sex revealed no significant effects on pain changes. Secondary analyses demonstrated no significant differences between the groups. DiscussionThe topical analgesic Bonipar demonstrates a comparable onset of action, with efficacy non-inferior to diclofenac in the management of musculoskeletal pain, while showing fewer adverse effects compared to diclofenac. These findings highlight the potential of Bonipar as a valuable alternative for the treatment of localized pain.

Non-contact identification of essential oils with IR sensors and analysis of components with an electronic nose

AbstractIn this study, the odour values of rosemary, mint, black cumin, lavender, and thyme oils were determined by an electronic nose working with an Arduino microprocessor. The components of the plants were compared with the sensor data, and the most sensitive sensors were determined by sorting according to the highest components. The study data indicated that the MQ3 sensor exhibited the highest sensitivity for thyme, black cumin, and lavender oils, which contain 63% carvacrol, 38% thymoquinone, and 36% linalool, respectively. Also, MQ7 was the most sensitive sensor for menthone (68%) in mint oil and eucalyptol (45%) in rosemary oil. In addition, a low-cost and non-contact device that works with an infrared sensor has been developed to detect the identity of the oil added into the vial. The study data showed that low-cost Arduino-based IR and odour sensors can determine the identity and component percentage of oils. The fact that the developed device can detect with 100 percent accuracy even in case of peppermint and rosemary oils, which are very similar in appearance, shows that the study data will be an inspiration for contactless determination of oil quality and type.

Profit and chemical analysis of Lavandula dentata L. and Rosmarinus officinalis L. essential oils and the influence of factors stressors

The anatomical, physiological, and environmental changes of plants can alter the production of essential oil. The present study aims to characterize the profit and chemical constituents of Lavandula dentata L and Rosmarinus officinalis L. essential oils (EO), grown under conditions of stress by solar, water and soil radiation. A completely randomized design (CRD) was used in triplicate. The biomass analysis showed that in both plants, the best results were obtained when it was subjected to lighting, shading and 100% fertilization, but there was the lowest profit of EO. The portion that had the lowest biomass, showed the highest profit of EO. In the EO of Lavandula dentata L there were as major compounds: nerol, linalol and Myrcene, respectively, as the product with the lowest profit, eucalyptol stood out, followed by camphor and fenchone. The EO of Rosmarinus officinalis L with the lowest profit showed alpha-pinene as the major constituent, followed by camphor, 1.8 cineol, alpha-Terpinolene and linalol, and the EO with the highest profit was caryophyllene. The constituents of the EO showed different results when comparing the products obtained from the highest and lowest profit, both qualitatively and quantitatively, which shows that plants under different stress conditions affect the production of these secondary compounds, which may indicate differences in pharmacological actions.
