Synopsis

Rosemary was irradiated with gamma irradiation at different doses (5 to 50kGy). The evaluation of irradiation depended on the chemical studies and Yield of extracted essential oils. Results showed significant difference for the essential oils yield at different doses. Compounds were identified for extracted essential oils from each of non – irradiated and irradiated rosemary leaves samples, the main components of essential oil extracted from either non-irradiated or irradiated rosemary were 1,8cineole, camphor, endo-borneol and D-limonene. However, a significant difference was observed when excceding a dose of 30KGy.
