摘要: Nine new gastrodin derivatives, including seven p-hydroxybenzyl-modified gastrodin ethers (1-7), 6'-O-acetylgastrodin (8), and 4-[α-D-glucopyranosyl-(1→6)-β-D-glucopyranosyloxy]benzyl alcohol (9), together with seven known derivatives, were isolated from an aqueous extract of Gastrodia elata ("tian ma") rhizomes. Their structures were determined by spectroscopic and chemical methods as well as single crystal X-ray diffraction. Compounds 1-4, 7, 10, and 11 were also isolated from a reaction mixture by refluxing gastrodin and p-hydroxybenzyl alcohol in H2O. As both gastrodin and p-hydroxybenzyl alcohol exist in the plant, the reaction results provide evidence for the production and increase/decrease of potential effective/toxic components when "tian ma" is decocted solely or together with ingredients in Chinese traditional medicine formulations, though the isolates were inactive in the preliminarily cell-based assays at concentrations of 10 μM. Moreover, using ultraperformance liquid chromatography high-resolution electrospray ionization mass spectrometry (UPLC-HRESIMS), 4, 7, 10, and 11, as well as component variations, were detectable in the freshly prepared extracts of different types of samples, including the freeze-dried fresh G. elata rhizomes.
