The plant extracts and fractions were prepared inDMSO and the correct volume was put in the first microplatewell with RPMI medium, for the concentration of each naturalcompound to be 250µg/mL in that well. The cell suspensionwas prepared in 0.85% saline, with an optical density equivalentto 0.5 McFarland standard, and diluted 1:100 in RPMI to obtaina final concentration of 1 × 104 to 5 × 104 colony-forming unitsper milliliter (CFU/mL). This suspension was inoculated in eachwell of a microdilution plate previously prepared with the plantextracts and fractions to give concentrations from 250µg/mLdown to 0.4µg/mL. The plates were incubated with agitation at37°C for 24 h for Candida species and 48h for Cryptococcusneoformans.
