Neglected tropical diseases are significant causes of death and temporary or permanent disability for millions living in developing countries. Unfortunately, there is no effective treatment for these diseases. Thus, this work aimed to conduct a chemical analysis using HPLC/UV and GC/MS to identify the major constituents of the hydroalcoholic extracts of Capsicum frutescens and Capsicum baccatum fruits, evaluating these extracts and their constituents' schistosomicidal, leishmanicidal and trypanocidal activities. The results obtained for the extracts of C. frutescens are better when compared to those obtained for C. baccatum , which can be related to the different concentrations of capsaicin ( 1 ) present in the extracts. The lysis of trypomastigote forms results for capsaicin ( 1 ) led to a significant value of IC 50 = 6.23 µM. Thus, the results point to capsaicin ( 1 ) as a possible active constituent in these extracts.
