Isolation of 3-O-(4'-hydroxybenzyl)-beta-sitosterol and 4-[4'-(4"-hydroxybenzyloxy)benzyloxy]benzyl methyl ether from fresh tubers of Gastrodia elata.
Two new 4-hydroxybenzyl alcohol derivatives (1 and 2) were isolated from the methanol extract obtained from fresh tubers of Gastrodia elata together with 4-hydroxybenzyl methyl ether, 4-hydroxybenzyl alcohol, bis(4-hydroxyphenyl)methane, 4-hydroxybenzaldehyde, beta-sitosterol and palmitic acid. 1 and 2 were identified as 3-O-(4'-hydroxybenzyl)-beta-sitosterol and 4-[4'-(4"-hydroxybenzyloxy)benzyloxy]benzyl methyl ether, respectively, according to the spectroscopic data.
