Abstract

Object To study the anthraquinone constituents in rhizoma and radix of Rheum sublanceolatum C Y Cheng et T C Kao Methods The constituents were isolated through column chromatography, and their structures elucidated through physicochemical and spectral analysis Results 6 anthraquinones were isolated and identified as chrysophanol (Ⅰ); physcion (Ⅱ); emodin (Ⅲ); emodin 8 O β D glucopyranoside (Ⅳ); aloe emodin 8 O β D glucopyranoside (Ⅴ) and citreorosein (Ⅵ) Conclusion All these compounds were isolated from R sublanceolatum for the first time
