[Study on chemical constituents of rhizome of Ardisia gigantifolia].

OBJECTIVE

To study the chemical constituents of the dried rhizome of Ardisia gigantifolia.

METHODS

The 60% ethanol extract was extracted with EtOAc, and then separated and purified by column chromatography using silica gel and preparative HPLC. Their structures were identified on the basis of spectral analysis and physico-chemical properties.

RESULTS

Nine compounds were isolated and identified as 11-O-galloylbergenin (1), 11-O-syringylbergenin (2), 11-O-protocatechuoylbergenin (3), 4-O-galloylbergenin (4), 11 -O-vanilloylbergenin (5), (-) -epicatechin-3-gallate (6), stigmasterol-3-O-beta-D-glucopyranoside (7), (-) -4'-hydroxy-3-methoxyphenyl-beta-D-[6-O-(4"-hydroxy-3", 5"-dimethoxybenzoyl)] -glucopyranoside (8), and beta-sitosterol (9).

CONCLUSIONS

Compounds 3, 4 and 7 were isolsted from the genus Ardisia for the first time, while compounds 1, 2, 5 and 6 were isolated from this plant for the first time.
