A chemotaxonomic study of flavonoids in the leaves of six Trichosanthes species

Abstract The 7-, 3′- and 4′-glucosides of luteolin, the 7-glucoside and 6,8-di- C -glucoside of apigenin were isolated from Trichosanthes kirilowii var. japonica . Kaempferol 3,7-di-rhamnoside and 3-glucoside-7-rhamnoside were identified from T. cucumeroides , kaempferol 3-galactoside and 3-sophoroside were also identified from T. anguina . Quercetin-3-rutinoside was detected from T. multiloba and T. rostrata. T. bracteata afforded luteolin 3′-glucoside and kaempferol 3-rutinoside, and T. kirilowii afforded luteolin 7-, 3′- and 4′-glucosides and apigenin 7-glucoside.
