title: [Chemical constituents from aqueous extract of Gastrodia elata].
abstract: Two new compounds (1 and 2), together with twenty-one known compounds (3-23), were isolated by a combination of various chromatographic techniques including column chromatography over macroporous resin, MCI gel, silica gel, and Sephadex LH-20 and reversed-phase HPLC. Their structures were identified by spectroscopic data analysis as 4-hydroxy-3-(4-hydroxybenzyl) benzyl methyl ether (1), 4-( methoxymethyl) phenyl-1-O-beta-D-glucopyranoside (2), hibicutaiwanin (3), 4-(4-hydroxybenzyl)-2-methoxyphenol (4), 4,4'-methylenebis(2-methoxyphenol) (5), L-phenyllactic acid (6) ,4-hydroxy-3-methoxybenzyl ethol ether (7), p-hydroxylbenzyl alcohol (8), p-hydroxylbenzyl methyl ether (9), p-hydroxylbenzyl ethyl ether (10), p-hydroxybenzaldehyde (11), p-hydroxybenzoic acid (12), p-hydroxybenzoic acid (13), gastrodin (14), 4-(ethoxymethyl) phenyl-1-O-beta-D-glucopyranoside (15), 4-(beta-D-glucopyranosyloxy) benzaldehyde (16), p-methylphenyl-1-O-beta-D-glucopyranoside (17 ), methyl-O-beta-D-glucopyranoside (18), 5-hydroxymethl-furan aldehyde (19), parishin (20), parishin B (21), parishin C (22), and diosgenin (23). The 13C-NMR data of compound 4 was first reported.
