The methanolic extract of the aerial parts of Lippia nodiflora Linn. afforded one new and two known steroids. The structure of the new steroid had been elucidated as 4',5'-dimethoxybenzoloxystigmasterol (1) by an analysis of the spectral data, including extensive NMR experiments and its chemical transformation to stigmasterol. The known steroids were identified as stigmasterol and beta-sitosterol through comparison of their spectral data with those reported in the literature.
过江藤地上部分的甲醇提取物得到了一种新的甾体化合物和两种已知的甾体化合物。通过对光谱数据的分析，包括广泛的核磁共振实验以及将其化学转化为豆甾醇，新甾体化合物的结构已被阐明为4',5'-二甲氧基苯并氧基豆甾醇（1）。通过将已知甾体化合物的光谱数据与文献报道的数据进行比较，确定它们为豆甾醇和β-谷甾醇。
