摘要

The phytochemical composition of medicinal and aromatic plants is influenced by environmental and genetic factors, including soil characteristics, climate, seasonal patterns, and cultivation practices. This study compared the chemical profiles and biological activities of essential oils and bioactive compounds from two ecotypes of Erodium glaucophyllum continental and insular. Gas chromatography–mass spectrometry revealed that monoterpene phenols were the predominant constituents in both essential oils, with eugenol accounting for 48.83% in the continental and 43.99% in the insular ecotype, representing the dominant chemotype. LC–MS analysis of methanolic and aqueous extracts identified seventeen compounds, with quinic acid (6047 ppm continental; 2807 ppm insular) and naringin (907.7 ppm continental; 462.9 ppm insular) being the most abundant, followed by rutin, hyperoside, gallic acid, and apigenin-7-O-glucoside. Essential oils exhibited strong antioxidant activity (IC₅₀ = 21.33 µg/mL continental; 23.25 µg/mL insular) and significant antibacterial effects, particularly against Gram-negative strains. Methanolic extracts contained the highest levels of total phenolics, flavonoids, and condensed tannins, correlating with elevated antioxidant and antimicrobial efficacy. Overall, the continental ecotype consistently outperformed the insular one in both bioactivity and compound richness. These results indicate that E. glaucophyllum, particularly the continental ecotype, represents a promising natural source of bioactive agents for pharmaceutical and health-related applications.
