Abstract
A method of isolating and purifying cucurbitacin is described. The method involves providing a cucurbitacin-containing liquid obtained from plant matter containing cucurbitacin, which liquid is then sequentially extracted with a non-polar solvent and then a moderately polar solvent. In a preferred embodiment, the cucurbitacin is purified by flash-column chromatography.
