[摘要]
目的:研究土家族藥用植物鐵箍散Schisandra propinqua var. sinensis根莖的化學成分。方法:采用硅膠柱色譜、凝膠柱色譜、制備高效液相色譜等方法分離化合物,根據理化性質和波譜解析鑒定各化合物的結構。結果:從鐵箍散中分離鑒定了2個倍半萜(化合物1、2)和4個木脂素(化合物3~6),分別為澤瀉醇(alismol,1)、匙葉桉油烯醇(ent-spathulenol,2)、五味子酯I(schisantherin I,3)、五味子酯F(schisantherin F,4)、propinquanin A(5)、propinquanin D(6)。結論:化合物1~4為首次從該植物中分離得到。

[Abstract]
Objective: To study the chemical constituents from Schisandra propinqua var. sinensis. Methods: The chemical comstituents were isolated by repeated column chromatography (Toyopearl HW-40C and HPLC) and their structures were elucidated on the basis of physico-chemical properties and spectroscopic features. Results: From the petroleum ether extract of the material, two sesquiterpene (compounds 1 and 2) and four lignan (compound 3–6) were isolated. Their structures were identified as: alismol (1), ent-spathulenol (2), schisantherin I (3), schisantherin F (4), propinquanin A (5), and propinquanin D (6). Conclusion: Compounds 1–4 are isolated from this plant for the first time.
