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-arabinopyranoside (3)-were isolated from the flowers of Aconitum paniculatum. Their structures were elucidated by 1D and 2D NMR studies ((1)H-(1)H COSY, HSQC, HMBC) as well as by HPLC-MS.

摘要

从圆锥乌头花中分离出三种新的乙酰化黄酮醇苷——山奈酚3 - O - β - (2'' - 乙酰基)吡喃半乳糖苷(1)、山奈酚3 - O - β - (2'' - 乙酰基)吡喃半乳糖苷 - 7 - O - α - 吡喃阿拉伯糖苷(2)和槲皮素3 - O - β - (2'' - 乙酰基)吡喃半乳糖苷 - 7 - O - α - 吡喃阿拉伯糖苷(3)。通过一维和二维核磁共振研究((1)H-(1)H COSY、HSQC、HMBC)以及高效液相色谱 - 质谱联用技术对它们的结构进行了阐明。
