Phytochemical compositions, antioxidant properties, enzyme inhibitory effects of extracts of four endemic Lathyrus L. taxa from Türkiye and a taxonomic approach

Lathyrus is an economically important genus, with different parts of some species used as foodstuff or animal feed. In this study, phytochemical compositions and bioactivities brachypterus var. brachypterus, L. haussknechtii, nivalis subsp. sahinii tefennicus taxa which are endemic to Türkiye were investigated. Total phenolic flavonoid contents (TPC, TFC) methanolic extracts detected. Then, compositions, antioxidant features (radical scavenging (DPPH: 1,1-diphenyl-2-picrylhydrazyl, ABTS: 2,2′-azino-bis(3 ethylbenzothiazoline) 6 sulfonic acid), reducing power (FRAP:Ferric ion power, CUPRAC:Cupric capacity), metal chelating activity (MCA), the phosphomolybdenum assays (PDA)) enzyme inhibitory properties also determined. The highest values found at for TPC, haussknechtii TFC. seen in DPPH, ABTS, FRAP, CUPRAC PDA assays, while extract MCA. was tyrosinase glucosidase AChE (acetylcholinesterase), BChE (butyrylcholinesterase) amylase. Finally, a taxonomic evaluation made by considering phytochemicals.
