Fig. 3From: Antimicrobial and antioxidant activities of triterpenoid and phenolic derivatives from two Cameroonian Melastomataceae plants: Dissotis senegambiensis and Amphiblemma monticolaEquivalent concentrations of tested samples scavenging 50% of DPPH radical (EC50). Results represent the mean ± standard deviation of the triplicate EC50 of each sample. Letters a - h indicate significant differences between samples according to one way ANOVA and Waller Duncan test; p < 0.05. Compounds 1–2, 11 and 14 were not tested; compounds 3–4, 9 and 13 were not active; DSEtOH = D. senegambiensis EtOH extract; DSEtOAc = D. senegambiensis EtOAc extract; DSBuOH = D. senegambiensis n-BuOH extract; AMEtOH = A. monticola EtOH extract; AMEtOAc = A. monticola EtOAc extractBack to article page
