超声波协同提取隐囊蕨黄酮物质及其抗氧化的研究

Extraction of Flavonoids From Notholaena hirsute(poir.)Desv with Ultrasonic Wave-cooperated Method and the Study of its Anti-oxidation

采用超声波协同提取隐囊蕨中黄酮物质,最佳提取条件为:在溶剂量(50%的乙醇)为80倍的情况下,超声波处理20min,在95℃下提取2h,黄酮得率为5.79%。隐囊蕨的黄酮提取液对羟自由基、超氧自由基有良好清除作用,并能有效阻断猪油的氧化。

The extraction and the anti-oxidation of flavonoids from Notholaena hirsute（poir） Desv were studied. The result showed that the yield of flavonoids is 5.79% extracted by 80 times of 50% alcohol for 2h at 95℃ and treatment of Ultrasonic wave for 20rain. The flavonoids extract can scavenge Oxygen and Hydroxy free radicals, and can stop the oxidation of the lard effectively.
