摘要: 深入研究草麻黄(Ephedra sinica Stapf)茎的化学成分。草麻黄茎经溶剂提取和萃取粗分离后,用硅胶柱色谱分离技术分离纯化化学成分,用1H NMR,13C NMR,MS等方法结合文献确定化学结构。从草麻黄茎的乙醇提取物中分离并鉴定了9个化合物:苯甲酸(1),反式肉桂酸(2),对羟基苯乙酸(3),绿原酸(4),原儿茶酸(5),鸟嘌呤(6),牧荆素(7),大黄酸(8),对氨基苯酚(10)。化合物3,6~9为首次从草麻黄中分离得到。

Abstract: This study was to investigate the chemical constituents of the stems of Ephedra sinica. After the plant materials were extracted and fractionated with solvents, column chromatography over silica gel was used to isolate and purified the compounds.The structures were elucidated on the basis of 1H NMR, 13C NMR,and MS analyses and comparison with the data of literatures.Nine compounds were isolated from this plant and their structures were identified as benzoic acid(1), trans-cinnamic acid(2),p-hydroxyphenylacetin acid(3),chlorogenic acid(4),protocatechuic acid(5),adenine(6),vitexin(7),rhein(8),and p-aminophenol(9), respectively. Compounds 3,6-9 were identified from the title plant for the first time.

Key words: Ephedra sinica, chemical constituents, flavanoids, organic acids
