A pair of sesquiterpene glucosides, 3-hydroxysolavetivone-beta-D-glucoside A (1) and 3-hydroxysolavetivone-beta-D-glucoside B (2), have been isolated from the leaves of Nicotiana tabacum. The former is a new compound, while the latter is a known one. Their structures were established by spectroscopic methods including (1)H, (13)C, and 2D NMR. The relative configuration of C-3 in compound 2 was revised by NOESY experiment.
从烟草叶片中分离出一对倍半萜糖苷,即3-羟基胡椒酮-β-D-葡萄糖苷A(1)和3-羟基胡椒酮-β-D-葡萄糖苷B(2)。前者是一种新化合物,后者是已知化合物。通过包括(1)H、(13)C和二维核磁共振在内的光谱方法确定了它们的结构。通过NOESY实验修正了化合物2中C-3的相对构型。
