Effect of Arak (Salvadora persica) and Cinnamon (Cinnamomum spp.) Extracts on Foulbrood Bacteria In vitro

Abstract

The antibacterial activity of the aqueous and ethanolic extracts of both Arak (Salvadora persica) and Cinnamon (Cinnamomum spp.) plants was evaluated on the foulbrood bacteria under the laboratory conditions instead of the synthetic antibiotics [it is surmised that is first time to evaluate Arak plant against the honeybee foulbrood pathogens]. The major antimicrobial constituents (total phenolics, flavonoids and tannins) were determined quantitatively in the extracts using the spectrophotometer technique. The results showed these extracts had significant antibacterial effects against the selected pathogens, Paenibacillus larvae and Melissococcus pluton.
