Antibacterial activity of a cardanol from Thai Apis mellifera propolis.

ABSTRACT:

Background

Propolis is a sticky, dark brown resinous residue made by bees that is derived from plant resins. It is used to construct and repair the nest, and in addition possesses several diverse bioactivities. Here, propolis from Apis mellifera from Nan province, Thailand, was tested for antibacterial activity against Gram(+ve) (Staphylococcus aureus and Paenibacillus larvae) and Gram(-ve) (Escherichia coli) bacteria.

Materials and methods

The three bacterial isolates were confirmed for species designation by Gram staining and analysis of the partial sequence of 16S rDNA. Propolis was sequentially extracted by methanol, dichloromethane and hexane. The antibacterial activity was determined by agar well diffusion and microbroth dilution assays using streptomycin as a positive
