Abstract

Infectious diseases continue to be an important public health problem. Among them, candidiasis an opportunist fungal infection especially in patients living with HIV / AIDS is on the increase. Our research team tested different plant extracts (butanolic, hexane, ethyl acetate, chloroform) of crude extract hydro-ethanolic obtained from Eucalyptus sp on the in vitro growth of Candida tropicalis. Among the 10 extracts tested, X1.2 has the highest inhibitory activity (MFC = 125 μg/mL; IC50 = 09.91 μg/mL). The method of preparation of the extract (X1.2) by partitioning of hydro-ethanolic extract in different solvent mixtures is the best way to obtain the best active principle concentration.
