ABSTRACT:
A process for the extraction and purification of the diterpene alcohol Plaunotol from the leaves of the medicinal plant, Croton sublyratus Kurz. The process involves extracting firstly with a lower aliphatic alcohol followed by extracting from the alcohol solution with a chlorinated hydrocarbon. Then impurities are hydrolysed and the required Plaunotol separated by extraction with a hydrocarbon. This process is simple and gave much better yields than prior processes.
