An extract of the stem of Gelsemium sempervirens has afforded a new oxindole alkaloid, 14 beta-hydroxygelsedine, whose structure and stereochemistry were deduced by spectral methods, principally high resolution 1H nmr, 2-D COSY, and decoupling experiments.
常绿钩吻茎的提取物得到了一种新的氧化吲哚生物碱，14β-羟基钩吻定，其结构和立体化学通过光谱方法推导得出，主要是高分辨率1H核磁共振、二维化学位移相关谱和去偶实验。
