Abstract
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.
