Abstract:
Pomegranate seed oil (PSO) is extremely rich and nutritious oil, which may be used for internally or externally for its medicinal properties. Pomegranate seed oil contain high levels of anti-oxidants that fight free radicals, skin aging, and the oil also is a potent source of punicic. Because of these properties, pomegranate seed oil is used to heal, protect, moisturize, nature, irritated skin, bring elasticity back to the skin and other skin problems.
In this research, a simple and high efficient ultrasound assisted emulsification microextraction (UAEME) technique was applied for separation and preconcentration of fatty acids of pomegranate seed. The effects of different variables on the extraction efficiency were studied simultaneously using an experimental design. The variables of interest in the UAEME were time and temperature of extraction, ratio of extracting solvent volume to the weight of the plant, emulsification time, type and volume of the micro emulsification solvent. A Plackett–Burman design was performed for screening in order to determine the significant variables affecting the extraction efficiency. Then, the significant factors were optimized by a Box–Behnken design (BBD) and the response surface equations were derived. The chemical compositions of the UAEME extract were identified by GC–MS and determined by GC–FID after derivation. The main components of the extracts under optimum USEME conditions were punicic acid, linoleic acid, linolenic acid, stearic acid and palmitic acid.
