TCAM = Terminalia canescens methanol extract, TCAW = Terminalia canescens water extract, and TCAE = Terminalia canescens ethyl acetate extract; - indicates no inhibition was observed at any concentration tested. MIC values of triplicate determinations (n = 3) are shown and are expressed in units of µg/mL.
