摘要

目的研究经眼草的化学成分及其体外抗氧化活性。方法采用溶剂萃取、重复硅胶柱层析、反相制备高效液相色谱等方法对其化学成分进行分离纯化。通过ESI-MS和NMR对其结构进行了鉴定。通过体外DPPH自由基清除实验对这些化合物的抗氧化活性进行了筛选。结果共分离得到10个化合物，分别为cosmosiin(1)、二氢咖啡酸(2)、咖啡酸(3)、异oliolide(4)、vomifioliol(5)、glecholone(6)、芹菜素(7)、aurantiamide(8)、(+)-lariciresinol(9)和()-丁香醇(10)。结论化合物2、4、8 ~ 10为首次从该植物中分离得到，化合物9、10为首次从该植物中分离得到的木脂素类化合物。DPPH自由基清除实验表明，化合物2、3、9和10具有潜在的抗氧化活性。

Chemical constituents from Glechoma longituba

Objective To study the chemical constituents from Glechoma longituba and their anti-oxidant activity in vitro.Methods The chemical constituents were isolated and purified by solvent extraction,repeated silica gel column chromatography,and reverse phase preparative HPLC.Their structures were identified on the basis of ESI-MS and NMR spectra.The anti-oxidant activities of these compounds were screened by DPPH free radical scavenging assay in vitro.Results Ten compounds were isolated and elucidated as cosmosiin(1),dihydrocaffeic acid(2),caffeic acid(3),isololiolide(4),vomifoliol(5),glecholone(6),apigenin(7),aurantiamide(8),(+)-lariciresinol(9),and()-syringaresinol(10).Conclusion Compounds 2,4,and 8—10 are isolated from the plants in Glechoma L.for the first time;Compounds 9 and 10 are lignans firstly obtained from this plant.DPPH free radical scavenging assays show that compounds 2,3,9,and 10 exhibit potential anti-oxidant activity.
