In the paper,the extraction conditions of flavonoids in apple peels were optimized based on microwave method and single factor experiment. The antioxidant abilities of flavonoids were also studied by using Trolox as the reference. The results showed that the extraction efficiency of flavonoids can reach 2. 50% under the optimum extraction conditions( solid-to-liquid ratio 1: 5,concertration ethanol 60%,microwave power 390 W,extraction time 2 min). The clearance rate of flavonoids extracted from apple peels ...
