绵头雪莲花的化学成分研究

目的:对西藏产绵头雪莲花Saussurea laniceps全草进行化学成分研究。方法:采用硅胶柱色谱法进行分离纯化,通过波谱解析进行结构鉴定。结果:从该藏药材乙醇提取物中分离得到15个化合物,分别鉴定为β-谷甾醇(1),伞形花内酯(2),对羟基苯乙酮(3),东莨菪素(4),异东莨菪素(5),雪莲内酯(6),3-(2′,4′-二羟基苯基)丙酸甲酯(7),芹菜素(8),neoechinulin A(9),胡萝卜苷(10),东莨菪素苷(11),雪莲内酯8-O-β-D-吡喃葡萄糖苷(12),芹菜素-7-O-β-D-葡萄糖苷(13),芹菜素-7-O-β-D-芦丁糖苷(14)和紫丁香苷(15)。结论:化合物5~15系首次从该植物中分离得到,其中化合物7,9系首次从该属植物中首次发现。

Studies on chemical constituents of Saussurea laniceps

OBJECTIVE: To investigate the chemical constituents of Saussurea laniceps. METHOD: The ethanol extract of S. laniceps was separated by means of silica gel chromatography. The compounds isolated from the plant were identified by their spectral evidence. RESULT: Fifteen compounds were isolated and identified as beta-stiosterol (1), umbelliferone (2), 4-hydroxyacetophenone (3), scopoletin (4), isoscopoletin (5), xuelianlactone (6), methyl 3-(2', 4'-dihydroxyphenyl) propanoate (7), apigenin (8), neoechinulin A (9), daucosterol (10), scopolin (11), xuelianlactone 8-O-beta-D-glcuoside (12), apigenin 7-glcuoside (13), apigenin 7-lutinoside (14) and syringin (15). CONCLUSION: Compounds 5-15 were isolated from S. laniceps, and among them, 7 and 9 were isolated from genus Saussurea for the first time.
