Screening of Native Plants from Yucatan for Anti–<i>Giardia lamblia</i>. Activity

Abstract

The in vitro. activity of 10 methanol extracts prepared from native plants collected in the Yucatan Peninsula [Byrsonima crassifolia. (L.) Kunth, Cupania dentata. DC., Diphysa carthagenensis. Jacq., Dorstenia contrajerva. L., Gliricidia sepium. (Jacq.) Kunth ex Walp., Justicia spicigera. Schldl., Pluchea odorata. (L.) Cass., Spigelia anthelmia. L., Tridax procumbens. L., and Triumfetta semitriloba. Jacq.] was evaluated against Giardia lamblia. trophozoites. All the extracts showed activity against G. lamblia. trophozoites. T. procumbens. was most active, with an IC50 of 6.34 µg/ml, followed by C. dentata., 7.59 µg/ml, D. carthagenensis., 11.53 µg/ml, and B. crassifolia., 15.55 µg/ml.
