Abstract

Abstract: Objective: To study the chemical constituents in Rumex japonicus. Methods: Isolation and purification from the ethyl
acetate extract of Rumex japonicus were carried out by column chromatography silica gel and Sephadex LH-20. Their structures were
elucidated based on the physical characteristics and spectroscopic data. Results: Seven compounds were isolated and identified as
chrysophanol（1）, citreorosein （2）, physcion（3）, rhein-8-O- β -D-glucopyranoside（4）, syringaresinol（5）, quercitroside（6）,
isoshinanolone（7）. Conclusion: Compounds 1-4 were anthraquinones, compounds 6 was flavonoid, and compounds 2, 4 and 5 were
isolated from this plant for the first time.

Key words: Rumex japonicus, ethyl acetate, chemical constituents
