Gamma-irradiation effect on the chemical composition and antibacterial activity of the Moroccan Tanacetum Annuum L. Essential Oil

Abstract

The study aims to evaluate the Moroccan Tanacetum annuum L. essential oil by studying the effect of gamma irradiation on both the chemical composition and antibacterial activity, this is done by exposing the oil extracted from the dry aerial parts of the plant by hydrodistillation to irradiation dose of 5kGy and 10kGy. The obtained results proved that irradiation technology can actually raise the percentage of chemical compounds that would increase the biological activity of the essential oil. This allows to increase the potential of the plant studied and its biological effectiveness, also the irradiation process has proven the ability to raise the quality of the chemical composition both in terms to reduce the risk of contamination it can be microbiological, physical, and chemical of one of the most abundant medicinal plants in northern Morocco.
