INTRODUCTION: Rosmarinus officinalis L. (C), member of the Lamiaceae family has been accepted as one of the spices with the highest antioxidant activity.
METHODS: At this study, the transmission electron microscopy (TEM), X-Ray Diffraction (XRD) and fourier transform infrared spectroscopy (FTIR) physicochemical characteristics of gamma-irradiated Rosemary nano structure were investigated.
RESULTS: The particle size distribution of the gamma-irradiated Rosemary prepared under irradiation at 30 kGy in a cobalt-60 irradiator exhibit a very narrow size distribution with average size of 70 nm. Results showed that irradiated (30 KGy) and crude Rosemary had a similar pattern of FTIR spectra, typical of phenol compound, without any notable changes in the key bands and functional groups status. The irradiated Rosemary with 50 KGy and 10 KGy showed the highest and lowest crystallinity, respectively. The Rosemary crystallinity of irradiated samples decreased, as compared with the non-irradiated sample.
DISCUSSION AND CONCLUSION: Therefore, 30 KGy can be optimum for synthesis nanoparticles, average size of 70 nm, with low crystalinity and without any notable change in key bands compare to non-irradiated.
