OBJECTIVE To study the chemical constituents of 95% EtOH extract of Mappianthus iodoides Hand.-Mazz..METHODS Various chromatographic techniques were used to separate and purify the constituents.The spectral data (MS and NMR) were obtained for structural elucidation.RESULTS One new megastigrane, mappiodol A (1), together with four known compounds,(1S,3S,5R,6R,9R)-megastigman-7-ene-3,9-diol-5,12-epoxide (2), 3-epifriedelionl (3), β-carboline (4)and harman (5), were isolated from the stems of M.iodoides.
