PROCESS FOR THE ISOLATION OF A PHARMACOLOGICALLY ACTIVE SUPROCESS FOR THE ISOLATION OF A PHARMACOLOGICALLY ACTIVE SUBSTANCE FROM COLEUS FORSKOHLII BSTANCE FROM COLEUS FORSKOHLII

摘要

A process for isolating a pharmacologically active substance from the plant Coleus forskohlii which comrises extracting the dried and ground plant material first with a hydrocarbon solvent such as herein described and then with a halogenated hydrocarbon such as herein described, evaporating the halogenated hydrocarbon extract to give a residue, extracting the residue with an alkanol such as herein described,m evaporating the alkanol extract to give a residue, subjecting the resulting residue to column chromatography as herein described, evaporating the eluted fractions to give a residue and recrystallising the residue from organic solvent such as herein described to give the pharmacologically active substance.
