The best extraction process of shikimic acid in star anise and oxidation resistance was mainly studied.With water as solvent , by refluxing extraction , ultrasonic extraction , microwave extraction of shikimic acid in star anise , the extraction process was optimized.Through single factor and orthogonal test , the optimal extraction technology for microwave extraction method obtained were 4 min, microwave power of 400 watts, material Liquid than 1:20 ( g/mL) , and shikimic acid yield was 4.92%. In the aspect of oxidation resistance with DPPH free radicals capture spectrophotometry was studied.Found shikimic acid on free radical clearance rate can reach 12.72%, with a certain resistance to oxidation.
