Abstract:
Objective To study the chemical constituents of the CHCl3 and EtOAc extracts from Artemisia frigida.Methods The chemical constituents in A.frigida.were isolated with silica gel and LH-20 chromatography and their structures were identified by means of spectra,in same cases by direct comparison with authentic samples.Results Thirteen compounds were obtained and identified as quercetin(Ⅰ),luteolin(Ⅱ),5,7,3'-triterhydroxy-4'-methoxy flavone(Ⅲ),5,7,3'-triterhydroxy-6,4'-dimethoxy flavone(Ⅳ),5,3'-dihydroxy-6,7,4'-tritermethoxy flavone(Ⅴ),5,3'-dihydroxy-3,6,7,4'-tetramethoxy flavone(Ⅵ),methyl phenol(Ⅶ),7-hydroxy coumarin(Ⅷ),7-methoxy coumarin(Ⅸ),caffeic acid(Ⅹ),?-sitosterol(Ⅺ),6,7-dihydroxy coumarin(ⅩⅡ),and 7-hydroxy-5,6-dimethoxy coumarin(ⅩⅢ).Conclusion All these compounds are isolated from this plant for the first time.
