目的：研究土家族藥用植物鐵箍散Schisandra propinqua var. sinensis根莖的化學(xué)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(jù)理化性質(zhì)和波譜解析鑒定各化合物的結(jié)構(gòu)。結(jié)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(jié)論：化合物1～4為首次從該植物中分離得到。

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.
