Kill kinetics of L. donovani promastigotes in relation to drug concentration and time. Cells were treated with different concentrations of (a) hexane fraction and (b) amphotericin B. The growth kinetic curves were plotted as number of viable parasites vs time with data collected every 24 h over a period of 120 h; NC = Negative control; Each data point represents mean ± SD from three experiments
