山楂核化学成分研究

A Study on Chemical Constituents in Seeds of Crataegus pinnatifida Bge.var. major N. E. Br.

目的:研究山楂核的化学成分。方法:采用大孔树脂和Sephadex LH20 柱对山楂核醇提物的水溶性部分进行分离,用1H,13CNMR 鉴定化学结构。结果:分得4 个化合物,分别为原儿茶酸,没食子酸,儿茶酚和对羟基苯甲酸。

Objective:To study the chemical constituents in the seed of Crataegus pinnatifida var. major .Method:Four compounds were isolated and identified by column chromatography and 1H, 13 C NMR data.Results:The compounds obtained were identified as protocatechuic aciod,gallic acid,catechol and p hydroxybenzoic acid.Conclusion:All the compounds were isolated from this plant for the first time.
