【摘要】 目的研究藤梨根(Actinidia chinensis root)的化学成分。方法利用各种色谱法进行分离,根据理化性质和波谱数据鉴定结构。结果从藤梨根的水提取物中分离得到8个酚类成分,分别鉴定为(-)-表儿茶素(1)、(+)-儿茶素(2)、秦皮素(3)、秦皮乙素(4)、原儿茶醛(5)、(-)-表儿茶素-5-O-β-D-吡喃葡萄糖苷(6)、erythro-1,2-bis-(4-hydroxy-3-methoxyphenyl)-1,3-propanediol(7)、threo-1,2-bis-(4-hydroxy-3-methoxyphenyl)-1,3-propanediol(8)。结论化合物3~8为从该植物中首次分离得到。更多还原

【Abstract】 OBJECTIVE To investigate the chemical constituents from the roots of Actinidia chinensis. METHODS The compounds were isolated and purified by column chromatography and their structures were elucidated by spectroscopic methods. RESULTS Eight compounds were obtained from the aqueous extract of the roots of Actinidia chinensis.. The structures were determined as(-)-epi-catechin( 1),( +)-catechin( 2),fraxetin( 3),escaletin( 4),protocatechuic aldehyde( 5),(-)-epi-catechin-5-O-β-D-glucopyranoside( 6),erythro-1,2-bis-( 4-hydroxy-3-methoxyphenyl)-1,3-propanediol( 7),and threo-1,2-bis-( 4-hydroxy-3-methoxyphenyl)-1, 3-propanediol( 8). CONCLUSION Compounds 3- 8 are isolated from the roots of Actinidia chinensis for the first time.更多还原
