Abstract
A new bisdesmodic triterpenoid saponin, dulcin was isolated from the s eeds of Pithecellobium dulce and was identified as 3-O-[beta-D-glucopy ranosyl lpha-L-arabinopyranosyl]-28-O-[beta-D-xylopranosyl (1-->6)-bet a-D-glucopyranosyl]-echinocystic acid. The known oleanolic acid saponi n P-E, oleanolic acid 3-O-beta-D-glucopyranosyl (1-->2)-alpha-L-arabin opyranoside was also obtained. The structural features were elucidated by a combination of spectroscopic methods and some chemical transform ations.
