A new triterpenoid saponin, named prostratoside A, vvas isolated from the whole plants of Polycmpon prostratuna. Its structure was determined to be 3-0-{β-D-xylopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)-β-D-g lucopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→2)]-α-L-arabinopyranosyl}-22α-acetosy-saikogenin G by spectroscopic methods.
- Polycarpon prostratum,
- caryophyllaceae,
- triterpenoid saponin,
- prostratoside A
