Chemical constituents from the roots of Actinidia chinensis / 中国药学杂志

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.
