Abstract
Flavonoids from the aerial parts of Lonicera syringantha Maxim.were studied.Five flavonoids were isolated and their structures were identified as luteolin(Ⅰ),luteolin-7-O-β-D-glucoside(Ⅱ),diosmetin(Ⅲ),diosmetin-7-O-β-D-glucoside(Ⅳ),cupressuflavone(Ⅴ).All these compounds were first isolated from this species,compounds Ⅲ,Ⅳ and Ⅴ were isolated from the genus Lonicera Linn.for the first time.
