Fractionation and Identification of Ethyl Ecetate Extract from Rhizoma Fagopyri Cymosi
摘要
Abstract
Objective： To fractionate the ethyl ecetate extract from Rhizoma Fagopyri Cymosi and identify the resulting fractions.Methods： Silica gel column chromatography,Sephadex LH-20 column chromatography and recrystailization were employed to fractionate the ethyl ecetate extract.According to physiochemical properties and spectral data,the fractions obtained were identified.Results： Thirteen compounds were separated from the ethyl ecetate extract and elucidated as glutinone（1）,isorhametin（2）,quercetin（3）,quercetin-3-O-α-L-rhamnoside（4）,eriodictyol（5）,catechin（6）,3,5-dimethoxy benzene carbonic acid-4-O-glucoside（7）,syringic acid（8）,p-hydroxyl-benzaldehyde（9）,succinic acid（10）,N-trans-coumaroyl tyramine（11）,sitosterol（12） and daucosterol（13）.Conclusion： For the first time,compounds 5,7 and 11 have been isolated from the genus of Fagopyrum,and compound 8 from Fagopyrum dibotrys（D.Don） Hara.关键词
