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