【Abstract】 Aim To study the chemical composition of Opuntia dillenii Haw. Methods Many kinds of chromatography methods were used in the isolation procedure, while the structures of isolated compounds were determined on the aids of NMR and MS spectral analysis. Result Three new compounds, together with 14 known compounds, were isolated form the 80% ethanolic extract of its stems. Conclusion The three new compounds, opuntioside I (2), 4 ethoxyl 6 hydroxymethyl α pyrone (3) and kaempferol 7 O β D glucopyranosyl (1→4) β D glucopyranoside (4), were characterized.更多还原
