The efficient hydrolysis of flavonoid glycosides hesperidin (1a), naringin (1b) and rutin (1c) to corresponding flavonoid aglycone hesperetin (24), naringnin (2b) and quercetin (2c) respectively by employing microwave irradiation (MWI) method was studied. The test was designed to investigate the influential factors of the hydrolysis process under a Microwave-assistance such as power of microwave, reaction temperature and irradiation time. The results show that microwave assistance can greatly accelerate the hydrolysis rate of flavonoid glycosides, shorten the reaction time, and increase the yield of flavonoid aglycone. The optimized parameters are : power 500-600 W, irradiation time 30-45 min, reaction temperature 80-90 degrees C. Therefore, the microwave assistance Method has many advantages, such as, it is highly effective, it consumes less time, it is environmentally friendly and higher product purities.
