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.
