Ultrasonic-microwave-assisted extraction of total flavonoids from Seed oil residue of Passiflora edulis Sims
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 4
Abstract
"The seed oil residue of Passiflora edulis Sims was used as the study object，and the flavonoids in the seed oil residue were extracted by ultrasonic-microwave-assisted methodology. First single-factor experiments were taken，such as ethanol concentration，solid-to-solvent ratio，ultrasonic power，ultrasonic time，microwave power and microwave time. The results showed that ultrasonic power and microwave time had a significant effect on the extraction rate of flavonoids；ultrasonic time，ethanol concentration，solid-to-solvent ratio and microwave power had a more significant effect on the extraction yield of flavonoids. Response surface methodology（ RSM） was applied to optimize the extraction result and a maximum extraction yield of total flavonoids was achieved. The optimal extraction conditions were 73.78% of ethanol concentration，1∶56.02（g/mL） of ratio between solid and liquid，300 W of ultrasonic power，50 min of ultrasonic time，160 W of microwave power，90 s of microwave time，by which the yield of flavonoids reached 117.53 mg/g. The extraction yield of flavonoids by ultrasonic-microwave-assisted methodology is 14.81% higher than that of ethanol extraction."
