我们曾经报告了中药天麻(Gastrodia elata Bl.)中的三个酚类成分,即:对羟甲苯基β-D-吡喃葡萄糖甙(天麻素,Ⅰ),对羟基苯甲醇(Ⅱ)和对羟基苯甲醛(Ⅲ),其中天麻素及对羟基苯甲醇已合成,二者在药理研究上已表现出镇静和催眠作用,临床试验也证实了它们对脑神经衰弱和头痛有效。基于上述事实,使我们有理由推断天麻的其他酚类成分也可能 We have reported three phenolic compounds in Gastrodia elata Bl., Namely: p-cresyl β-D-glucopyranoside (gastrodin, Ⅰ), p-hydroxybenzyl alcohol (Ⅱ) Hydroxybenzaldehyde (III), in which gastrodin and p-hydroxybenzyl alcohol have been synthesized, both of which have shown sedative and hypnotic effects in pharmacological studies, have also been shown clinically to be effective against neurasthenia and headache. Based on the above facts, it is reasonable to conclude that other phenolic constituents of Gastrodia elata are also possible
