Abstract

An alkaloid of the molecular formula C₂₁H₁₉NO₆ was isolated from the roots of berberis actinacantha. Substructures were derived from proton and carbon-13-NMR data. Single-crystal x-ray diffractometry identified the alkaloid as 15(R,S)-3,4-dimethoxy-11,12-methylenedioxy-8,14-dioxo-hexahydro-iso-homoprotoberberin. ORTEP plots, bond angles, assigned carbon-13 and proton NMR data are given.
