The structure of the new base isolated from Stephania Sasakii HAYATA was revealed as 1, 2-methylenedioxy-4-hydroxyporphine (III) from ultraviolet, infrared, nuclear magnetic resonance and mass spectra. Absolute configuration of the 6a-position was found to be R from the result of.optical rotatory dispersion, but the steric configuration of the alcoholic hydroxyl in 4-position still remains to be clarified.
