OBJECTIVE
To study the chemical constituents of Gastrodia elata.
METHODS
The compounds were isolated by silica gel column chromatography and recrystallization and their structures were elucidated by spectral analysis.
RESULTS
The structures of 14 compounds were identified as: p-hydroxybenzyl alcohol (1), p-hydroxybenzaldehyde (2), 3, 4-dihydroxybenzaldehyde (3), 4, 4'-dihydroxy, dibenzyl ether (4), 4-hydroxymethyl benzyl-4'-hydroxy-3'-(4"-hydroxy benzl) benzyl ether (5), 4-ethoxybenzyl alcohol (6), anisic alcohol (7), bis(3, 4-dihydroxyphenyl) methane (8), 4, 4'-dihydroxydiphenyl methane (9), 2, 4-bis(4'-hydroxy-benzyl)-phenol (10), 4-( methoxymenthyl) benzene-1, 2-diol (11), p-methylphenyl-1 -O-beta-D-glucopyranoside (12), N6-(4'-hydroxybenzl) -adenosine (13) and beta-sitosterol (14).
CONCLUSIONS
Compounds 6 - 8 and 11 are isolated from this plant for the first time.
