Abstract:
OBJECTIVETo study the chemical constituents of Lysidice brevicalyx.
METHODVarious chromatographic techniques were used to isolate and purify the constituents such as column chromatography on silica gel, Rp-silica gel, Sephadex LH-20 and HPLC. The structures were elucidated by chemical evidence and spectroscopic methods.
RESULTSeven compounds were isolated from the 95% ethanol extract of the leaves of L. brevicalyx and these compounds were elucidated as 2-0-[1-(3-methylbutyryl)phloroglucin-ol]-beta-D-glucopynanoside (1), 3-beta-D-glucopyranosyloxy-4, 5-dimethoxy-benzoic acid (2), benzyl alcohol O-beta-D-glucopyra noside (3), polydatin (4), quercetin-3-alpha-L-rhamnopyranoside (5), ethyl gallate (6), benzyl 6-O-alpha-L-arabinofurano syl-beta-D-glucopynanoside (7).
CONCLUSIONAll Compounds were isolated from this plant for the first time. Compounds 2, 3, 5-7 were obtained from this genus for the first time.
