[Objective]The study aimed to research the best extraction process of flavonoids from Passiflora edulis.[Method] The effect of ethanol concentration(A),ratio of raw material to solvent(B),microwave extraction time(C)and microwave power(D)on flavonoids yield were investigated by orthogonal design.[Result]The results showed that the ethanol concentration and microwave power had a significant impact on the flavonoids yield.The optimal conditions were the ethanol concentration 60%,ratio of raw material to solve...
