Parasite Killing of Leishmania (V) braziliensis by Standardized Propolis Extracts

Figure 1

Dose-response effect of propolis extract on L (V). braziliensis promastigote viability. Parasites were incubated for 96 h with 10, 50, or 100 ug/mL of either (a and d) dry, (b and e) alcoholic, or (c and f) glycolic propolis extract. Bars represent means ± SD of two representative experiments performed in quadruplicate. AUC accounts for Area under the Curve and it corresponds to the area of the geometric figure made by the concentration curve of a drug as a function of time. The Kruskal–Wallis nonparametric test, followed by Dunn’s posttest, was used to compare among experimental groups (, , and, posttest for linear trend, ).
