Abstract:
From the leaves of Cucumis sativus the following C-glycosides were isolated and identified: isovitexin 2"-O-glucoside, isovitexin, isoorientin, 4'-X-O-diglucosides of isovitexin and swertiajaponin. In the flowers of the above species chromatographically (HPLC, TLC) the presence of kaempferol 3-O-rhamnoside and 3-O-glycosides of kaempferol, quercetin, isoramnetin was revealed. The flavonoids complexes occuring in other species of Cucumis: C. metuliferus, C. myriocarpus and six cultivar varieties of C. sativus chromatographically (HPLC, TLC) were campared.
