A new lignan glycoside, 6-acetyl-1-[1,3-(4,4'-dihydroxy-3,3'-dimethoxy-beta-truxinyl)-beta-d-fructofuranosyl]-alpha-d-glucopyranoside (1), named impecyloside, was isolated from the rhizomes of Imperata cylindrica. The structure of the compound was determined by spectroscopic data including FABMS, UV, IR, 1H NMR and 13C NMR (DEPT) and 2D NMR (COSY, HSQC, HMBC).
从白茅的根茎中分离出一种新的木脂素苷，6-乙酰基-1-[1,3-(4,4'-二羟基-3,3'-二甲氧基-β-吐昔联苯酰基)-β-D-呋喃果糖基]-α-D-吡喃葡萄糖苷(1)，命名为白茅苷。该化合物的结构通过光谱数据确定，包括快原子轰击质谱(FABMS)、紫外光谱(UV)、红外光谱(IR)、核磁共振氢谱(1H NMR)、核磁共振碳谱(13C NMR，含DEPT)以及二维核磁共振谱(COSY、HSQC、HMBC)。
