MIC and MIC90 values were calculated in μg/mL Ethanolic Extract (Et-E); Dichloromethane Fraction (DCM-F); n-Butanol Fraction. (Bu-F); Methicillin-resistant Staphylococcus aureus (MRSA). Different superscripts (a, b, c & d) for a given value within a column indicate significant difference at p < 0.05 using Duncan’s Multiple Range test (DMRT).
