[Abstract]
Objective To investigate the chemical constituents of Abacopteris penangiana.Methods Compounds were separated and purified by column chromatography with silica gel,RP C18,and Sephadex LH-20.The structures of the obtained compounds were elucidated on the basis of physicochemical properties and spectroscopic methods.Results Seven compounds were purified and their structures were identified as:(7′Z)-3-O-(3,4-dihydroxy phenylethenyl)-caffeic acid(1),cafeicin B(2),matteucinol(3),protocatechuin acid(4),p-methoxybenzoic acid(5),β-sitosterol(6),and β-daucosterol(7).Conclusion Compound 1 is a new compound named abacopteric acid,and compounds 2-7 are isolated from the plant for the first time.
