Vk. Saxena et M. Singhal, NOVEL TRITERPENOIDAL SAPONIN FROM THE SEEDS OF PITHECELLOBIUM DULCE, Proceedings of the Indian Academy of Sciences. Chemical sciences, 110(4), 1998, pp. 409-414
A novel triterpenoid saponin was isolated from the seeds of Pithecello
bium dulce, which has been identified as 3-O[beta-D-glucopyranosyl (1
--> 2)-alpha-L-arabinopyranosyl] 28-O [alpha-L-rhamnopyranosyl(1 --> 4
) beta-D-glucopyranosyl (1 --> 4) beta-D-glucopyranosyl] echinocystic
acid by spectral analysis and chemical degradation methods.
