1/2 × minimum inhibitory concentration (MIC) of grapefruit seed extract (GSE) (S. aureus ATCC 6538, 50 μg/ml; S. aureus ATCC 12692, 25 μg/ml; S. aureus ATCC 25923, 100 μg/ml).

All experiments were performed in triplicates, and reported values represent the mean ± standard error.

^a-cValues with different letters in the same column are significantly different (p < 0.05).
