Abstract: A new selaginellin derivative named as selaginellin S (1) was isolated from the whole plants of Selaginella pulvinata (Hook. et Grev.) Maxim. (Selaginellaceae), together with a known one (selaginellin M, 2). Compounds 1 and 2 were separated and purified by silica gel and Sephadex LH-20 column chromatography. Their structures were determined on the basis of extensive spectroscopic analysis including IR, MS, 1D and 2D NMR experiments, as well as ECD calculations. Compound 1 is a key intermidiant in the biosynthesis pathway of selaginellins. Compound 2 is first reported in this plant.
从垫状卷柏（卷柏科）全草中分离得到一个新的卷柏素衍生物，命名为卷柏素S（1），同时还得到一个已知化合物（卷柏素M，2）。化合物1和2通过硅胶柱色谱和葡聚糖凝胶LH-20柱色谱进行分离纯化。通过红外光谱、质谱、一维和二维核磁共振实验以及电子圆二色计算等广泛的光谱分析确定了它们的结构。化合物1是卷柏素生物合成途径中的关键中间体。化合物2首次在该植物中报道。
