[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.
