摘要： Cucurbitacin B (CuB) and cucurbitacin E (CuE) were separated from the fruit base of Cucumis melo L. by high-speed countercurrent chromatography (CCC) using a two-phase solvent system composed of hexane/ethyl acetate/methanol/water (12:24:16:9 by volume). Three successive 300mg injections of sample, indicated by HPLC assay to contain 61.4% CuB and 35.1% CuE, were made at leap-frog intervals, prior to emergence of the second peak, thereby greatly reducing the overall separation time. Measurement of the stationary phase retention indicated that many more sample injections can be made without renewing the column contents.
