Abstract

Abstract Aim To study the chemical constituents of Selaginella stautoniana . Methods The compounds were isolated and purified by Diaion HP-20, Toyopearl HW-40, silica gel column chromatography and their structures were identified by physico-chemical and spectral methods, respectively. Results Seventeen compounds were obtained and identified as isovanillic acid ( 1 ), p -hydroxybenzoic acid ( 2 ), 3, 4, 5-trimethoxyphenol ( 3 ), vanillic acid ( 4 ), 2-methoxyhydroquinone ( 5 ), p -hydroxyphenol( 6 ), 3, 4, 5-trimethoxybenzoic acid ( 7 ), hydroferulicacid ( 8 ), hydrocaffeic acid ( 9 ), p -hydroxy phenylethanol ( 10) , umbelliferone ( 11 ), apigenin- 6, 8-di- C -β-D-glucopyranoside ( 12 ), 2, 3-dihydroamentoflavone ( 13 ), bilobetin ( 14 ), quercetin-3- O -α-L-rhamnopyranoside ( 15 ), kaempferol-3- O -α-L-rhamnopyranoside ( 16 ) and amentoflavone ( 17 ). Conclusion Compounds 1–16 were isolated from this plant for the first time.
