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,Ⅰ)、三白脂素 - 8(saucernetin- 8,Ⅱ)和三白脂素 - 7(saucernetin- 7,Ⅲ)。结论 它们均为首次从该植物中分得的新木脂素类化合物。

Object To study the chemical constituents of Saururus chinensis (Lour.) Baill..Methods The constituents were isolated and repeatedly purified on kieselgel/silica gel column. They were identified and structurally elucidated by physico-chemical constants and spectral anlysis. Results 3 compounds were obtained. They were saucernetin (Ⅰ)，saucernetin-8 (Ⅱ) and saucernetin-7 (Ⅲ).Conclusion All of them are neolignans isolated for the first time from this plant.
