Abstract
This research isolated two new oleanane-type triterpene glycosides, named mocochinosides A (1) and B (2), together with ten known compounds as chikusetsusaponin IVa ethyl ester (3), momordin Ib (4), momordin IIb (5), momordin II (6), calenduloside G (7), calenduloside H (8), elatoside A (9), elatoside C (10), calendulaglycoside C 6'-O-7-butyl ester (11), and hederagenin 3-O-β-D-glucuronopyranoside (12) and characterized them from the vines of Momordica cochinchinensis. The new structures of both glycosides 1-2 were elucidated by spectroscopic analysis including 2 D NMR and MS, followed by an analysis of their anti-inflammatory and cytotoxic activities. Compounds 1, 4, and 11 showed moderate inhibitions for NO production on RAW264.7 macrophages induced by LPS at IC50 5.41 ∼ 11.28 μM. Compounds 3, 4, and 7 (IC50 8.42 ∼ 19.74 μM) exhibited potential anti-proliferative activities against both of WiDr and MCF-7 human tumor cell lines.
