目的 研究三白草 Saururus chinensis(L our.) Baill.的化学成分。方法 采用硅藻土柱层析和反复硅胶柱层析分离纯化 ,通过理化常数测定和光谱分析鉴定其化学结构。结果 从三白草中分得了 3个化合物 ,即三白脂素(saucernetin, )、三白脂素 - 8(saucernetin- 8, )和三白脂素 - 7(saucernetin- 7, )。结论 它们均为首次从该植物中分得的新木脂素类化合物
Objective To study the chemical composition of Saururus chinensis (Lour.) Baill. Methods Separation and purification were carried out by column chromatography on diatomaceous earth and repeated silica gel column chromatography. The chemical structure was identified by physicochemical constants and spectral analysis. Results Three compounds were isolated from Saururus chinensis, namely, sacerernetin, saucernetin-8, and seven-saucernetin-7. Conclusion They are all new lignan compounds that have been isolated from this plant for the first time
