Objective To investigate the chemical constituents from Opuntia dillenii. Methods The chemical constituents of O. dillenii were isolated and purified by various column chromatographies. Structures were identified by their physicochemical characteristics and spectral features. Results Five compounds were isolated from the 80% ethanol extract in the cladodes of O. dillenii and identified as 6R*-9, 10-dihydroxy-4-megastigmen-3-one (1), (?)-syringaresinol-4-O-β-D-glucopyranoside (2), succinic acid (3), (E)-ferulic acid methyl ester (4), and D-tartaric acid (5). Conclusion Compound 1 is a new compound named opuntione. Compound 2 is isolated from the plants of Opuntia Mill. for the first time.
