Özet
This study comprehensively evaluated the phytochemical composition and multidimensional biological activities of Sisymbrium altissimum L., a wild edible species belonging to the Brassicaceae family. Methanolic extracts obtained from aerial parts, flowers, fruits, and roots were successively fractionated using solvents of increasing polarity, and essential and fatty oils were characterized by GC-MS and GC-FID analyses. The essential oil composition showed marked organ-dependent variation, with methallyl cyanide dominating fruit (91.9%) and flower (75.9%) oils, while phenylethyl isothiocyanate (48.7%) was the major constituent in roots. Further phytochemical investigation of the biologically active root hexane extract led to the isolation of beta-sitosterol, lauric acid, and beta-sitosterol-3-O-glucoside. Biological activity assays revealed strong alpha-glucosidase inhibition, particularly in the root hexane extract (87.92%), exceeding the reference drug acarbose (68.49%), whereas alpha-amylase inhibition was moderate, with the root ethyl acetate fraction exhibiting the highest activity (40.84%). Cholinesterase inhibition assays demonstrated low to moderate acetylcholinesterase and butyrylcholinesterase inhibitory activities depending on the plant part and extract fraction. Hyaluronidase inhibition was notably high, reaching up to 98.70%, whereas moderate collagenase (27.56%) and elastase (23.98%) inhibition and low tyrosinase activity were observed. Antioxidant activity was prominent in ethyl acetate and n-butanol fractions, with ABTS radical scavenging values approaching those of standard antioxidants. Total phenolic and flavonoid contents correlated with antioxidant capacity, although structural factors also influenced activity. Importantly, all tested extracts and cold-pressed oil exhibited no mutagenic or genotoxic effects in the Ames/Salmonella assay. Overall, these findings provide a comprehensive characterization of S. altissimum and highlight its potential as a source of biologically active natural products.
