【Abstract】 Objective To determine the optimal extraction process of flavonoids in antlion. Methods Using the ultrasonic auxiliary method to extract the flavonoids in the antlion, it is to investigate the effect of different solvents, extraction methods and ultrasonic extraction conditions on the extraction rate of flavonoids, through single factor and L9(34) orthogonal test. Result The best extraction solvent of flavonoids is ethanol in antlion, the ultrasonic extraction method is the best way, the optimum orthogonal optimization ultrasonic extraction conditions are as follows:the ethanol volume fraction 90%, material liquid ratio l:15, extraction time 60 min. Conclusion the average extraction rate of flavonoid reach to 2.13% in antlion, through the orthogonal optimization technology, which is stable and reliable.更多还原
