Abstract
Three new acetylated flavonol glycosides-kaempferol 3-O-beta-(2''-acetyl)galactopyranoside (1); kaempferol 3-O-beta-(2"-acetyl)galactopyranoside-7-O-alpha -arabinopyranoside (2), and quercetin 3-O-beta-(2"-acetyl)galactopyranoside-7-O-alpha -arabinbpyranoside (3)-were isolated from the flowers of Aconitum paniculatum. Their structures were elucidated by 1D and 2D NMR studies (H-1-H-1 COSY, HSQC, HMBC) as well as by HPLC-MS.
