凤丹牡丹鲜花原液清除DPPH自由基功效研究

Effect of Scavenging DPPH Free Radical on the Original Solution of Peony Flower

目的:探究凤丹牡丹鲜花原液的抗氧化能力。方法:采用高效微波联合压榨过滤法、蒸馏法制备牡丹鲜花原液,对其进行DPPH自由基清除试验以评价其抗氧化能力,并与玫瑰鲜花纯露进行对比。结果:高效微波联合压榨过滤法制备的牡丹鲜花原液在浓度为1%~7%时,对DPPH自由基的清除率达到24.87%~89.50%,优于蒸馏法制备的牡丹鲜花原液以及鲜花纯露类产品。结论:凤丹牡丹花瓣经高效微波联合压榨过滤法提取的鲜花原液比传统制备方法得到的产品功效性更显著,可作为一种优质的功效性化妆品原料生产与应用。

Objective:To explore the antioxidant capacity of the original liquid of peony and peony.Methods:the raw liquid of peony flower was prepared by high efficiency microwave combined press filtration and distillation.DPPH free radical scavenging test was carried out to verify its antioxidant capacity,and compared with rose flower pure dew.Results:the DPPH free radical removal rate of the peony flower original liquid prepared by high efficiency microwave combined press filtration method was 24.87%~89.50%when the concentration was 1%~7%,which was better than that of the peony flower original liquid and the pure flower dew product prepared by distillation.Conclusion:the original liquid of peony flower extracted by high efficiency microwave combined press filtration is more effective than the traditional method,and can be used as a high quality cosmetic material.
