摘　　要：Objective To study the chemical constituents of Pronephrium triphyllum.Methods The chemical constituents in the plant were isolated and purified with silica gel and Sephadex LH-20.Their structures were identified by analyses of spectral data and physicochemical properties.Results Six compounds were isolated and identified as shelincaoide A(1),n-butyl-β-D-fructopyranoside(2),triphyllin A(3),6,7-di-hydroxycoumarin(4),daucosterol(5),and β-sitosterol(6),respectively.Conclusion Compound 1 is found to be a new compound.Compounds 2 and 4 are firstly isolated from the plants in Pronephrium Presl.and all compounds except 3 are obtained from the species for the first time.Objective To study the chemical constituents of Pronephrium triphyllum.Methods The chemical constituents in the plant were isolated and purified with silica gel and Sephadex LH-20.Their structures were identified by analyses of spectral data and physicochemical properties.Results Six compounds were isolated and identified as shelincaoide A(1),n-butyl-β-D-fructopyranoside(2),triphyllin A(3),6,7-di-hydroxycoumarin(4),daucosterol(5),and β-sitosterol(6),respectively.Conclusion Compound 1 is found to be a new compound.Compounds 2 and 4 are firstly isolated from the plants in Pronephrium Presl.and all compounds except 3 are obtained from the species for the first time.
