Figure 4

Antifungal activities of 1 (a), 2 (b), and 3 (c) against Candida albicans at different concentrations. Graphs on the left show log scale CFU (colony forming unit) numbers of C. albicans in each treatment. The percentage in the right graphs was calculated as follows: (CFU number in each compound treatment/CFU number of control) × 100. Each bar represents the average and standard deviation of 9 replicates. Student’s t-test was performed between the control and each treatment; **p < 0.01.
