(3β,7S,20α)-11-Methoxy-19α-methyl-2-oxoformosanan-16-carboxylic acid methyl ester

Description

The stem, stem bark, root and root bark of Cabucala fasciculata have been found to contain a number of new alkaloids which have been chiefly investigated by Titeux and his colleagues. This base is separated from the accompanying alkaloids by column chromatography. It forms colourless crystals which melt over a very wide range of temperature. Isocarboxine A has a specific rotation of [α]_D + 31.7° (CHC13).
