Bioassay-guided separation of citreorosein and other oestrogenic compounds from Polygonum cuspidatum.
Citreorosein was isolated from P. cuspidatum as a new oestrogenic compound, together with emodin and its glucoside, by silica gel column chromatography and preparative high-performance liquid chromatography sequentially. Oestrogenic activity was determined by a recombinant yeast assay.
