Fig. 3. Cytotoxic effect of the (A) FD-RKF extract (total set) and (B) Fresh-RKF extract (total set) on hPBMCs. RPMI medium without the sample was used as the negative control, whereas 20% v/v DMSO was used as the positive control. The percentage of survival cells is represented as meanĀ±SD. The statistical differences between groups were analyzed using one-way ANOVA. The letters (a-f) showed statistically significant differences at P<0.05. FD-RKF extract, freeze-dried powder of ripening karanda fruit extract; Fresh-RKF extract, fresh ripening karanda fruit extract; hPBMCs, human peripheral blood mononuclear cells; RPMI, roswell park memorial institute; DMSO, dimethyl sulfoxide.
