A new glucoside, named gastrodioside, was isolated from the tubers of Gastrodia elata BLUME. (Orchidaceae) and its structure was elucidated as bis (4-hydroxybenzyl)-ether mono-β-D-glucopyranoside (6). 4-Hydroxybenzaldehyde (1), 4-hydroxybenzyl alcohol (2), 4-hydroxybenzyl methyl ether (3, possibly an artifact), 4-(4'-hydroxybenzyloxy)benzyl methyl ether (4), bis (4-hydroxybenzyl) ether (5), 4-(β-D-glucopyranosyloxy) benzyl alcohol (7) and tris [4-(β-D-glucopyranosyloxy)benzyl] citrate (parishin, 8) were also isolated. This is the first time that compounds 4 and 5 have been isolated from natural sources.
从天麻(Gastrodia elata BLUME,兰科)的块茎中分离得到一个新化合物,命名为天麻苷,其结构被阐明为双(4-羟基苄基)醚单-β-D-吡喃葡糖苷(6)。同时分离得到的还有4-羟基苯甲醛(1)、4-羟基苄醇(2)、4-羟基苄基甲醚(3,可能为人为产物)、4-(4'-羟基苄氧基)苄基甲醚(4)、双(4-羟基苄基)醚(5)、4-(β-D-吡喃葡糖氧基)苄醇(7)和三[4-(β-D-吡喃葡糖氧基)苄基]柠檬酸酯(穗花杉双黄酮,8)。这是首次从天然来源中分离出化合物4和5。
