摘 要:目的:优化艾草黄酮提取工艺,并评价艾草黄酮抗氧化活性。方法:以艾草总黄酮得率、DPPH自由基清除率、OH自由基清除率为指标,确定艾草黄酮的提取方法;在单因素试验和Plackett-Burman试验基础上,通过响应面试验优化了超声—微波辅助水提法提取艾草黄酮的工艺条件。结果:最佳提取工艺条件为60℃水浴40 min,340 W超声27 min,600 W微波120 s,料液比1∶30(g/mL);该条件下艾草总黄酮得率可达87.93 mg/g,DPPH自由基清除率为80.84%,OH自由基清除率为77.92%。结论:该提取方法艾草黄酮的得率显著优于传统煎煮和水浴加热提取法(P<0.05),且具有较好的抗氧化活性。Objective:To optimize the extraction process of flavonoids from Artemisia argyi and evaluate the antioxidant activity in vitro.Methods:The ultrasonic-microwave combined water extraction method of Artemisia flavonoids was determined,and the extraction process was studied with the yield of total flavonoid,DPPH radical scavenging rate and·OH radical scavenging rate of Artemisia argyi.Based on the single factor experiment,the factors with greater influence were screened through Plackett-Burman design,then optimized extraction process by response surface test.Results:The best extraction process was ultrasonic power 340 W,ultrasonic time 27 min,microwave power 600 W,microwave time 120 s,solid-liquid ratio 1∶30(g/mL).Under these conditions,the yield of total flavonoids can reach 87.93 mg/g,DPPH radical scavenging rate is 80.84%,·OH radical scavenging rate is 77.92%.Conclusion:The yield of flavonoids by this method is significantly better than the traditional boiling and water bath extraction(P<0.05),and the antioxidant activity of Artemisia argy is better.
