山楂叶化学成分的研究

Studies on the Chemical Constituents of the Leaves of Crataegus pinnatifida Bge. var. major N. E. Br.

从山楂叶的乙醇提取物热水萃取部分分离鉴定了7个化合物。它们分别是对羟基苯甲苹果酸(Ⅰ)、槲皮素(Ⅱ)、金丝桃甙(Ⅲ)、牡荆素(Ⅳ)、牡荆素鼠李糖甙(Ⅴ)、盐酸二乙胺(Ⅵ)与山梨醇(Ⅶ)。

Compounds were isolated from the aqueous extract of the leaves of Crataegus pinnatifida var. major and seven of them were identified as 2-(4-hydroxybenzyl)malic acid, quercetin, hyperin, vitexin, rhamnosylvitexin, diethylamine hydrochloride and sorbitol respectively by UV, IR, NMR, MS, some chemical techniques by comparison with the standard spectra of known compounds.
