Abstract
Three bisdesmosidic saponins, 20-hydroxyecdysone, and quercetin-3-O-beta-D- galactoside were isolated from the methanol extract of the aerial parts of Achyranthes aspera L. (Amaranthaceae). Their structures were established on the basis of NMR spectroscopic analysis; the complete H-1 and C-13 assignm ents of the compounds were achieved by means of 2D NMR studies.
