Wright grows wild and is cultivated as one type of traditional medicinal plant in China.The EtOH extract of fresh rhizomes of D.zingiberensis was concentrated and partitioned further to produce petroleum ether-,ethylacetate-,n-butanol-and water-soluble fractions.The water-soluble fraction was subjected to column chromatography on macro resin AB-8,and was further purified on a SephadexLH-20 chromatograpic column; the final products were obtained by repeated reversed-phase ODS and MCI gel CHP 20P column chromatography to give seven steroidal saponins.
