Abstract
An alkaloid of the molecular formula C21H19NO6 was isolated from the roots of B. actinacantha. Substructures were derived from 1H- and 13C-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-homoprotoberberine. ORTEP plots, bond angles, assigned 13C and 1H-NMR data are given.This publication has 0 references indexed in Scilit:
