Summary

Preliminary Study on the Chemical Composition of Ardisia insularis

Belonging to the Family of Myrsinaceae in Vietnam

Three compounds, gallic acid (1), methyl gallate (2) together one megastigmane glucoside, (3S, 5R, 6R, 7E, 9S)-megastigman-7-ene-3,5,6,9-tetrol 3-O-β-D-glucopyranoside (3) have been isolated from the aqueous fraction of the leaves of Ardisia insularis Mez. belonging to the family of Myrsinaceae. The structure elucidation of these compounds was performed based on spectroscopic data (MS, 1D-NMR, 2D-NMR). This is the first time (3S, 5R, 6R, 7E, 9S)-megastigman-7-ene-3,5,6,9-tetrol 3-O-β-D-glucopyranoside was isolated from the genus Ardisia.

Keywords: Ardisia insularis Mez., Myrsinaceae, (3S,5R,6R,7E,9S)-megastigman-7-ene-3,5,6,9-tetrol 3-O-β-D-glucopyranoside.
