Abstract
Propolis is a sticky, non toxic, soft resinous substance produced by honey bees. The chemical composition of propolis depends upon the collecting time, location and plant source resulting in the biological activity variation. The aim of this study was to analyze the chemical composition of propolis by using Gas chromatography – Mass spectrometer. Bee propolis is a natural medication applied topically and is considered to have antibacterial, antifungal, antiviral, antibiotic, antioxidant properties and is used for treatment of many infections. Propolis was found to be rich in alkaloids, saponins, tannins and resins. The chemical characterization revealed the presence of 9 distinct phytochemical compounds using GC – MS and the most predominant compound were S Methyl – L – Cysteine (62.36%) followed by Cis – 2,3 – Epoxyoctane (31.78%). The different concentrations of methanolic extracts of propolis showed varied antibacterial activities against B. cereus with highest zone of inhibition (19.0 mm).
