Compounds isolated from medicinal plants presented notable amoebicidal activities against amoeba. Briefly, isolated compounds at a concentration of 100 µg/mL were incubated with 5 × 10⁵ of A. castellanii overnight, at 30 °C. Following this, viable amoebae were calculated using haemocytometer microscopically. The data are expressed as the mean ± standard error. p values were determined using two-sample t-test, two-tailed distribution, (*) is p < 0.05.
