Triterpenoids and their glycosides from Terminalia chebula
摘要:
Two new triterpenoid glycosides, chebuloside I and II were isolated from the stem bark of Terminalia chebula and shown to be beta-D-galactopyranosyl 2alpha,3beta,23-trihydroxyolean-12-en-28-oate and beta-D-glucopyranosyl 2alpha,3beta,6beta,23-tetrahydroxyolean-12-en-28-oate, respectively, based on their spectral data and some chemical transformations.
