目的:研究五味子藤茎的化学成分。方法:采用各种色谱技术进行分离纯化,结合化合物的理化性质与波谱数据进行结构鉴定。结果:从五味子藤茎95%乙醇的冷浸提取物中分离得到10个化合物,分别鉴定为:五味子甲素(1)、五味子乙素(2)、五味子丙素(3)、gomisin N(4)、五味子醇甲(5)、安五酸(6)、二氢愈创木脂素(7)、十四烷酸(8)、β-谷甾醇(9)、胡萝卜苷(10)。结论:其中,化合物6~8为首次从五味子藤茎中分离得到。 Objective: To study the chemical composition of schisandra chinensis. Methods: A variety of chromatographic techniques were used to separate and purify the compounds. The physicochemical properties and spectral data of the compounds were used to identify the structures. Results: Ten compounds were isolated from the cold-dipping extracts of 95% ethanol from the stems of Schisandra chinensis. They were identified as: Schizandrin (1), Schizandrin B (2), Schizandrin (3), gomisin N (4). ), Schizandrol A (5), annonalic acid (6), dihydroguaiacol (7), tetradecanoic acid (8), β-sitosterol (9), and carotenoid (10). Conclusion: Among them, compounds 6~8 were isolated from the stems of Schisandra chinensis for the first time.
