摘要
为了研究梵净山野生阳荷红色素的最佳提取工艺及抗氧化性,采用超声波法从提取功率、温度、时间和料液比4个单因素的基础上,用L9(34)正交实验法,对超声波提取野生阳荷红色素的工艺条件进行了优化。实验结果表明:梵净山野生阳荷红色素的最佳工艺条件为:料液比1∶25(g/mL),提取温度50℃,提取功率450W,提取时间30min。提取率为24.16%。因此,采用超声波法具有短时、高效、节能的优点,可用于阳荷红色素的提取。另外,采用POV值测定法和Fenton反应研究阳荷红色素的抗氧化性,结果表明:阳荷红色素具有较强的抗氧化作用。
The object was to study on optimum extraction and anti-oxidation of the wild Zingiber strioatum haematochrome from Fanjing Mountain.Ultrasonic extraction method was adopted on the basis of extraction power,temperature,time and liquid-material ratio to optimize its process conditions of extracting the wild Zingiber strioatum haematochrome by means of L9（34）orthogonal test.The results showed that the optimal process conditions of the wild Zingiber strioatum haematochrome from Fanjing Mountain were as follows：liquid-material ratio 1：25（g/mL）,extraction temperature 50℃,power 450W,time 30min.And extraction rate was 24.16% under this condition.Therefore,ultrasonic extraction could shorten the extraction time,improve the extraction efficiency and save the energy,thus which might be adopted for the extraction of Zingiber strioatum haematochrome.In addition,by adopting the POV value determination and Fenton reaction to study the anti-oxidation of Zingiber strioatum haematochrome,the result showed that Zingiber strioatum haematochrome had strong anti-oxidation.
