| 中文摘要: |
| 以紫果西番莲种籽油粕为研究对象，利用超声微波双辅助法提取油粕中的黄酮，研究乙醇体积
分数、料液比、超声功率、超声时间、微波功率、微波时间6 个因素对黄酮提取率的影响，结果表明，超声
时间、乙醇体积分数、料液比、微波功率对黄酮提取率影响极显著，超声功率、微波时间对黄酮提取率影响
显著。采用响应面分析法优化提取工艺参数为：乙醇体积分数73.78%、料液比1∶56.02（g/mL）、超声功率
300 W、超声时间50 min、微波功率160 W、微波时间90 s，该条件下黄酮提取率为117.53 mg/g，比常用的乙
醇浸提法提高14.81％。 |
| 英文摘要: |
| 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. |
