1992
Tsurumi, S. | Takagi, T. | Hashimoto, T.
A new triterpenoid saponin was isolated from Pisum sativum and characterized as 3-O-[a-L-rhamnopyranosyl-(1 leads to 2)-beta-D-galactopyranosyl (1 lead to 2)-beta-D-glucuronopyranosyl(1 leads to)]-22-O-[3'-hydroxy-2'-methyl-5',6'-dihydro-4'-pyrone(6'leads to)]-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.
