Abstract
Background: Silene conoidea, a member of the Caryophyllaceae family, is a rare edible weed in Iran. It possesses various medicinal properties, including insecticidal, antimicrobial, antibacterial, and allelopathic effects.
Methods: This study represents the investigation into the phytochemical contents, compounds, and biological activities of six different fractions [petroleum ether, chloroform, dichloromethane, ethyl acetate, methanol, and water] obtained from the leaves and stems of this species, with the aim of developing new natural drugs.
Result: The methanol fractions of both the leaves and stems exhibited the highest levels of total phenolic and flavonoid contents and demonstrated strong antioxidant activity in the DPPH free radical scavenging method, with IC50 values of 5.1± 1.34 and 9.67 ± 0.02 μg/mL, respectively, surpassing the activity of BHT. Additionally, the chloroform and methanol fractions showed moderate antimicrobial activity against bacterial strains, with MIC values ranging from 0.0625 to 0.5 mg/ml when compared to gentamicin. The more active fractions [chloroform and methanol] were further analyzed to identify bioactive compounds. GC-MS analysis detected forty and forty-five compounds, representing 97.97% and 99.22% of the total composition, in the chloroform fractions of the leaves and stems, respectively. The main constituents of the leaves were fatty acid derivatives [54.66%] and terpene derivatives [21.94%], whereas the stems contained terpene derivatives [40.46%] and hydrocarbon derivatives [31.41%]. LC-ESI-MS analysis of the methanol fractions revealed the presence of common groups, including flavonoids, steroids, and triterpenoid saponins. Several bioactive compounds have been identified, including rutin, kaempferol-neohesperidoside derivative, diosmin, sileneoside, hesperidin, luteolin-di-O-glucoside, orientin-O-glucoside, vitexin- O-rhamnoside, and swertisin-O-glucoside. Heatmap analysis was conducted to visualize the differences in metabolite profiles among the samples.
Conclusion: The analyzed fractions contained compounds with potential pharmacological activities.
期刊介绍：
Current Topics in Medicinal Chemistry is a forum for the review of areas of keen and topical interest to medicinal chemists and others in the allied disciplines. Each issue is solely devoted to a specific topic, containing six to nine reviews, which provide the reader a comprehensive survey of that area. A Guest Editor who is an expert in the topic under review, will assemble each issue. The scope of Current Topics in Medicinal Chemistry will cover all areas of medicinal chemistry, including current developments in rational drug design, synthetic chemistry, bioorganic chemistry, high-throughput screening, combinatorial chemistry, compound diversity measurements, drug absorption, drug distribution, metabolism, new and emerging drug targets, natural products, pharmacogenomics, and structure-activity relationships. Medicinal chemistry is a rapidly maturing discipline. The study of how structure and function are related is absolutely essential to understanding the molecular basis of life. Current Topics in Medicinal Chemistry aims to contribute to the growth of scientific knowledge and insight, and facilitate the discovery and development of new therapeutic agents to treat debilitating human disorders. The journal is essential for every medicinal chemist who wishes to be kept informed and up-to-date with the latest and most important advances.
