A gamma-pyronyl-triterpenoid saponin from Pisum sativum.
A new triterpenoid saponin was isolated from Pisum sativum and characterized as 3-O-[alpha-L-rhamnopyranosyl-(1----2)-beta-D-galactopyranosyl(1----2)-be ta- D-glucuronopyranosyl(1----)]-22-O-[3'-hydroxy-2'-methyl-5',6'-dihy dro-4'- pyrone(6'----)]-3 beta, 22 beta, 24-trihydroxyolean-12-ene. The name chromosaponin I is proposed. Chromosaponin I yielded soyasaponin I, known as phytochrome inhibitor, during extraction, but the latter was not found in the free form in this plant.
