[Chemical constituents of methanol portion of Illicium henryi].

To study the chemical constituents of the methanol portion of the stem of Illicium henryi. The methanol portion was isolated and purified by HP-20, ODS, Sephadex LH-20 column chromatography, and preparative HPLC. Their structures were elucidated by MS and spectral data(1H, 13C-NMR). Five compounds were isolated from the methanol portion and identified as benzyloxy-1-O-beta-D-glucopyranoside (1), 4-hydroxy-phenethyl alcohol-O-beta-D-glucopyranoside (2), 3-methoxyl-4-hydroxyl-phenpropanol-O-beta-D-glucopyranoside (3), 3-methoxyl-4-O-beta-D-glucopyranosyloxy-benzoic acid methyl ester (4), and 4-O-beta-D-glucopyranosyloxy-benzoic acid methyl ester (5). All compounds were isolated from this plant for the first time.
