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.
