毛菊苣根化学成分研究

Chemical Constituents from the Roots of Cichorium glandulosum

从毛菊苣的根分离鉴定了9个化合物,分别为β-谷甾醇(1)、旋覆花素(2)、山莴苣苦素(3)、咖啡因(4)、香草醛(5)、3,4,5-三甲氧基-桂皮酸甲酯(6)、5,8,3′,4′-四羟基-7-甲氧基黄酮(7)、5,8,4′-三羟基-7,3′-二甲氧基黄酮(8)和黄芩苷(9)。其中化合物2、6、7、8、9为首次从该属植物中分离。

Nine compounds were isolated from the roots of Cichorium glandulosum and their structures were elucidated as β-sitosterol（1）, inulicin（2）, lactucopicrin（3）, caffeine（4）, vanillin（5）, methyl 3,4,5-trimethoxy-cinnamicate（6）, 5,8,3′,4′-tetrahydroxy-7-methoxy flavone（7）, 5,8,4′-trihydroxy-7,3′-dimethoxy flavone（8） and baicalin（9）. Compounds 2, 6, 7, 8 and 9 were isolated from genus Cichorium for the first time.
