Triterpene saponins from Myrsine pellucida

Phytochemistry. 1994 Dec;37(6):1671-7. doi: 10.1016/s0031-9422(00)89590-4.

Abstract

Quercitol, five saponins and 3-O-(6'-O-palmitoyl) beta-D-glucopyranosyl stigmasterol were isolated from the stem bark of Myrisine pellucida. These compounds are described for the first time in this plant and their structures were determined using a combination of 1H and 13C NMR, and mass spectroscopy. The two saponins are new compounds, 3-O-(alpha-L-rhamnopyranosyl (1-->2) beta-D-glucopyranosyl (1-->4) alpha-L-arabinopyranosyl) cyclamiretin A and 3-O-(beta-D-xylopyranosyl) (1-->2) beta-D-glucopyranosyl (1-->4) [beta-D-glucopyranosyl (1-->2)] alpha-L-arabinopyranosyl) cyclamiretin D.
