Abstract:
Objective To investigate the chemical constituents in the whole plant of Hedyotis corymbosa.Methods The compounds were isolated by column chromatography,pre-TLC,and recrystallization.Their structures were elucidated by spectroscopic methods.Results Thirteen compounds were isolated and identified as(+)-lyoniresinol-3?-O-?-D-glucopyranoside(Ⅰ),quercetin(Ⅱ),esculetin(Ⅲ),scopoletin(Ⅳ),hedyotiscone A(Ⅴ),p-hydroxybenzoic acid(Ⅵ),protocatechuic acid(Ⅶ),vanillic acid(Ⅷ),syringic acid(Ⅸ),(+)-vomifoliol(Ⅹ),(-)-dihydrovomifoliol(Ⅺ),S-(+)-dehydrovomifoliol(ⅩⅡ),and alizarin 1-methyl ether(ⅩⅢ),respectively.Conclusion Compounds Ⅰ—ⅩⅢ are isolated from this plant for the first time.
