With their ability to bind to voltage-gated sodium channels, they keep these channels constantly active and cause tissue damage. However, despite this feature, the use of Rhododendron leaves or its secondary products as an alternative product is especially common in Turkey. This study aims to evaluate the possible dose-related effects of GTX-III in ischemia-induced in vitro cell models. Within the scope of the study, an ischemia model was established in two different cell lines (H9c2 and Cos-7) and treated with various concentrations of GTX-III. In this context, cell viability, cytotoxicity, apoptosis and necrosis were examined. In the results of MTT, a significant decrease (+p < 0.05) in cell viability was observed in all GTX-III concentrations in H9c2 cells compared to the control, while a significant difference (+p < 0.05) was observed in Cos-7 cells, especially at the 24th hour. LDH cytotoxicity was increased in a dose-dependent manner in both cell models. It was concluded that GTX-III caused apoptosis, and reduced cell viability in ischemia models; however, promoted cell proliferation in healthy cells. Based on the literature review, this study is the first to document the cytotoxic properties and apoptotic potential of GTX-III in an in vitro cell culture ischemia model. Our findings support the usage of GTX-III, however it should be remembered that the dose needs to be verified before being used medically.","PeriodicalId":14437,"journal":{"name":"International Journal of Secondary Metabolite","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44055372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a small tree from the Lauraceae family. The leaves of L. nobilis are the most exploited part of the plant due not only to the high produced quantity but to the large benefits and extensive use in different fields including culinary, cosmetic, therapeutic, and pharmacologic. The various beneficial health properties attributed to bay leaves are related to the presence of various bioactive compounds. Chemically, they contain numerous essential elements, some vitamins, and many secondary metabolites such as essential oils (cineole, linalool, and eugenol), phenolic compounds, particularly phenolic acids (ferulic, protocatechuic, and caffeic acids, etc.) and flavonoids (such as catechin, kaempferol, apigenin, quercetin, and their derivatives), and alkaloids (noraporphins and aporphins). Laurel leaves are not only used to flavor dishes, but present several beneficial properties that justified their traditional use against numerous illnesses, particularly for rheumatism, indigestion, and diarrhea. Bay leaves are an essential component of several industrial applications including agrifoods, cosmetics, and pharmaceuticals. Due to the presence of cited chemical constituents in bay leaves, various biological and pharmacological properties have been reported such as antioxidant, antibacterial, fungicidal, antiviral, insecticidal, wound healing, antimutagen, anticonvulsant, analgesic, anti-inflammatory, and immunostimulatory activities. This review provides an overview of L. nobilis leaves, beginning with botanical aspects, including its preparation and composition, followed by a discussion about the most abundant bioactive compounds, and finally the traditional uses and therapeutic effects.","PeriodicalId":14437,"journal":{"name":"International Journal of Secondary Metabolite","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42362591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several bioactive substances with antibacterial and antioxidant activities are abundant in essential oils. Some essential oils have also been employed in medicine. Due to the risk associated with employing synthetic preservatives, the use of essential oils as natural additives for extending the shelf life of food products has also drawn considerable attention. They are used in the pharmaceutical, cosmetic, and food industries for their functional properties. There are various methods for extraction, but both the quality and the percentage yield of essential oil never remain the same. So, innovative and non-conventional techniques of essential oils extraction from medicinal plants were evoled to get quantitative and qualitative yield. In the present article, we searched and reviewed innovative techniques used for the extraction of essential oils from medicinal and aromatic plants through electronic searches of PubMed, Medline, Wiley, Scopus, and Google Scholar. For the extraction of essential oils, several innovative/non-conventional techniques have been reported in literature. Extraction of essential oil by using innovative techniques retards the risk of losing the essential components of plants, maintains the quality, reduces chemical risk, extraction time, acts eco-friendly, and increases the percentage yield of the essential oils. This paper presents the success story of innovative extraction methods of essential oils in accordance with sustainable development and environmental protection.","PeriodicalId":14437,"journal":{"name":"International Journal of Secondary Metabolite","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45201264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antioxidant activities of hexane and methanol extracts of C. sempervirens L. were assessed in vitro using five complementary methods, including the β-carotene-linoleic acid assay for lipid peroxidation activity, the DPPH•, ABTS• assays for radical-scavenging activity, the CUPRAC method, and metal chelating methods. In addition, the phenolic profiling of the methanol extracts of the seeds and cones was analyzed using LC-HR/MS, for the first time. According to the findings, the antioxidant activity of the methanol extract obtained from seeds appears to be higher than that of cones in all assays. The methanol extracts of the seeds showed higher activity with an IC50: 24.081.06, IC50: 6.080.19, and A0.5: 18.600.63 µg/mL in the DPPH•, ABTS•, and CUPRAC assays, respectively than the BHA, and α-TOC. Also, the methanol extract of the cones showed strong activity with an IC50: 38.870.03 and A0.5:103.534.33 in ABTS• scavenging and CUPRAC assays. Moreover, twenty-eight phenolics were determined in the seeds while twenty-one phenolics were determined in the cones of the C. sempervirens using LC-HR/MS. The amounts of fumaric acid, vanilic acid, (-)-epicatechin, quercetin, hispidulin 7-glucoside, hyperoside, and quercitrin in the seeds are higher than those in the cones. Therefore, the results suggested that there was a strong relationship between the antioxidant activities of the extracts and their phenolic ingredients.","PeriodicalId":14437,"journal":{"name":"International Journal of Secondary Metabolite","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42923535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both isolates exhibited remarkable antibacterial potential against Gram-positive and Gram-negative clinical isolates. The AMCs of both SYS 1 and SYS 2 exhibited excellent antibacterial activity against Salmonella paratyphi B and Staphylococcus aureus. Both AMC-producing isolates were characterized and identified. Bacillus species SYS 1 and SYS 2 were identified as Bacillus amyloliquefaciens SYS 1 and Bacillus siamensis SYS 2, respectively. The highest antimicrobial activity of AMC produced by Bacillus amyloliquefaciens SYS 1 was exhibited against Salmonella paratyphi B (28 mm), followed by Staphylococcus aureus (26 mm). Bacillus siamensis SYS 2 AMC extracted by the solvent ethyl acetate exerted the highest antimicrobial activity against Salmonella paratyphi B (18 mm), followed by Staphylococcus aureus (16 mm). A partial characterization of the AMC was conducted and evaluated to contain amino acids and proteins.

Firstly, the inhibitory effect of the propolis on mycelial growth in Potato Dextrose Agar (PDA) media containing its ethanol extract (PE) at various concentrations (0.003, 0.06, 0.125, 0.25, 0.5, and 1 ppm/mL) was investigated under in vitro conditions. Then to assess the effect of PE on non-defoliating (PHCVd3 isolate) and defoliating (PHCVd47 isolate) pathotypes of V. dahliae, the varieties Giza 45 (resistant), Carmen (tolerant), and Acala SJ2 (susceptible) treated with PEE (1 ppm/mL) were observed in the plant growth chamber up to the 4-6 leaf stage. The whole in vitro experiments were carried out with three replicates, and the studies in vivo experiment were with five replicates depending on a completely randomized parcels design. The most effective dose of PEE with1 ppm/mL dose resulted in 75.2% suppression against the PHCVd3 isolate, while the effect of the same dose against the PHCVd47 isolate was 74.4%. The lowest disease severity index (DSI) values against PHCVd3 and PHCVd47 isolates in cotton cultivars treated with PE were 1.34 and 1.64 in the Giza 45, respectively, and the highest DSI values were 3.80 and 3.90 in the Acala SJ2 cultivar in vivo experiment, respectively. The findings indicate that PE treatment has a promising effect against cotton wilt disease that could be combined with known plant protection strategies.","PeriodicalId":14437,"journal":{"name":"International Journal of Secondary Metabolite","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43581307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
