Table 2 MIC and IC50 values determined for the phytochemical constituents

From: In vitro toxicity determination of antifungal constituents from Combretum zeyheri

Sample MIC IC50
Ethanol extract - 16 μg/ml
Alkaloid-enriched fraction - 20 μg/ml
Saponin-enriched fraction - 100 μg/ml
Flavonoid-enriched fraction - 159 μg/ml
Miconazole 6.25 μg/ml 1.1 μg/ml
  1. The IC50 was determined as the concentration that caused a reduction in 50 % of the growth based on the absorbance value at 590 nm of the positive growth control sample. The minimum inhibitory concentration (MIC) is the lowest concentration of an antimicrobial that will inhibit the visible growth of a microorganism. (-) indicates that no MIC was obtained
