BHA was used as a standard in all antioxidant assays except chelating ability of ferrous ion and total antioxidant capacity methods where EDTA and ascorbic acid were considered as positive controls respectively. Streptomycin was used as a reference in antibacterial methods. In each row, dissimilar letters denote significant alterations between sample and standard (p < 0.05)
