连钱草的化学成分研究

Chemical constituents of Glechoma longituba

摘要: 目的对连钱草地上全草进一步进行化学成分的研究。方法应用多种色谱法分离连钱草中的化学成分，采用多种光谱分析法鉴定它们的结构。结果从连钱草全草中又得到9个化合物，即连钱草酮(1)、6R,9R-3-氧代-α-紫罗兰醇(2)、S(+)-去氢催吐萝芙叶醇(3)、催吐萝芙叶醇(4)、可乐苏酸(5)、槲皮素(6)、豆甾烯醇(7)、肉豆蔻酸(8)和正三十烷醇(9)。结论化合物1为未见报道的新化合物，化合物2～9均为首次从该植物中分离得到。

Abstract: AimTo study the chemical constituents of Glechoma longituba (Nakai) Kupr. Methods Manifold chromatography methods were used to separated the chemical constituents, and the chemical structures were determined by spectral analyses. ResultsNine compounds were isolated from Glechoma longituba and identified, as: glecholone (1), 6R,9R-3-oxo-α-ionol (2), S(+)-dehydrovomifoliol (3), vomifoliol (4), corosolic acid (5), quercetin (6), stigmastenol (7), myristic acid (8) and triacontanol (9). ConclusionCompound 1 is a new compound. Compounds 2-9 were isolated from this plant for the first time.
