Abstract

The lipophilic insecticides DDT and HCH in sennae leaves and pods are removable by extraction with supercritical carbon dioxide in the pressure region at 100 bar. The effective ingredients, the sennosides, are not extracted and remain in the drug of which they can be easily extracted with water.
