ABSTRACT:
A method for the extraction of pharmacologically active components from the oleander plant using supercritical carbon dioxide and combining the extraction with other isolation methods. The extraction is carried out using carbon dioxide at supercritical conditions, with or without the addition of a modifier. The isolated product is recovered in higher yield than with traditional hot water extraction.
