A new triterpenoid saponin, named prostratoside A. was isolated from the whole plants of Polycarpon prostratum. Its structure nas determined to be 3-O-{beta-D-xylopyranosyl- (1-->2)- beta-D-glucopranosyl-(1-->4)-[ beta- D-plucopyranosyl-(1-->2)]-alpha-L-arabinopyranosyl}- 22 alpha- acetoxy saikogenin G by spectroscopic methods..
