				        	 Objective: Processing technology and antioxidant activity in vivo of pomegranate superfine powder were investigated. Methods: Processing technology of superfine powder of Granati Pericarpium was optimized using single-factor tests and response surface methodology (RSM). The antioxidant effect in vivo of superfine powder of Granati Pericarpium with different particle, vitamin E, and normal saline were studied. Results: The optimally grinding conditions for Granati Pericarpium were grinding time of 25 min, grinding temperature of -17℃, and input quantity of 198 g. Under the optimally grinding conditions, the minimum particle size of superfine powder of Granati Pericarpium was 7.68 μm which was close to the predicted value of 7.96 μm. Therefore, the established regression model has good prediction capability. Experimental results show that the superfine powder and vitamin E groups compared with the coarse powder and blank groups could significantly improve the activity of SOD, CAT, and GSH-Px, and reduce the content of MDA in serum of mice. Conclusion: The ability of superfine powder group on the protection of membrane lipid peroxidation and scavenge free radical is quite superior. It indicates that the active ingredients in the superfine powder of Granati Pericarpium could be dissolved better and more quickly in solvent than those in coarse powder. Therefore, the superfine powder of Granati Pericarpium has the better anti-oxidant effect in vivo.
