title: Two new triterpenoid glycosides from the leaves of Anthocephalus chinensis.
abstract: Nine compounds were isolated from the leaves of Anthocephalus chinensis by column chromatography on silica gel and Sephadex LH-20, and their structures were elucidated by spectroscopic techniques as clethric acid-28-O-β-d-glucopyranosyl ester (1), mussaendoside T (2), β-stigmasterol (3), hederagenin (4), ursolic acid (5), clethric acid (6), 3β,6β,19α,24-tetrahydroxyurs-12-en-28-oic acid (7), mussaendoside I (8), and cadambine (9). Compounds 1 and 2, and 7 and 8 were isolated from the plants of this genus for the first time, and compounds 1 and 2 were new triterpenoid glycosides.
