1A voucher herbarium specimen is a pressed plant sample deposited for future reference. Vouchers deposited at UEC herbarium (http://www.ib.unicamp.br/herbario/) at Biology Institute (IB) of UNICAMP, SP, Brazil. (—) Species with no voucher number registered. 2 The EOs were considered bactericidal when the MBC : MIC ratio was between 1 : 1 to 2 : 1, and bacteriostatic if this ratio was higher than 2 : 1.
