Effect of the bitter melon extracts eluted by different concentrations of methanol on the daunomycin accumulation by Caco-2 cells. The accumulation of daunomycin was measured after incubating the Caco-2 cells at 37°C for 2 h with or without a bitter melon extract eluted by different concentrations of methanol (2 mg ml⁻¹). Each data value is expressed as a percentage of the control, and is presented as the mean±s.d. (n=3). ^abcThe values not sharing common superscript letters are significantly different as P<0.01.
