title: Separation of Cucurbitacins by Overpressure Layer Chromatography from Hemsleya gigantha1.
abstract: Mixtures of cucurbitacins were obtained from an ethanol extract of H. GIGANTHA tubers. Purification was achieved by using the over-pressure layer chromatographic (OPLC) technique to yield cucurbitacin-F, 23,24-dihydrocucurbitacin-F, cucurbitacin-F-25- O-acetate, and 23,24-dihydrocucurbitacin-F-25- O-acetate.
