| 中文摘要: |
| 采用单因素试验和响应面法对油梨粕中总黄酮的提取工艺进行优化，并研究其抑制α-葡萄糖苷酶活性作用。结果表明：油梨粕总黄酮最佳提取工艺条件为提取温度65?℃、提取时间27 min、乙醇体积分数60%、液料比30∶?1、提取次数1次，此条件下油梨粕总黄酮得率可达9.25%；油梨粕总黄酮提取物具有较好的抑制α-葡萄糖苷酶活性作用。 |
| 英文摘要: |
| The extraction process of total flavonoids from Persea americana Mill. meal was optimized by single factor experiment and response surface methodology, and its inhibitory effect on α-glucosidase activity was studied. The results showed that the optimal extraction conditions of total flavonoids from Persea americana Mill. meal were obtained as follows: extraction temperature 65?℃，extraction time 27 min, volume fraction of ethanol 60%, ratio of liquid to material 30∶?1 and extraction times once. Under the optimal conditions, the yield of total flavonoids reached 9.25%. The total flavonoids extract of Persea americana Mill. meal had a good inhibitory effect on α-glucosidase activity. |
