| 摘 要： | 采用苯酚-硫酸,并以超声法辅助提取野生藿香枝叶中的多糖,设计L9(34)正交试验考察料液比、pH和超声提取时间对藿香枝叶中多糖提取的影响,并对藿香多糖进行清除.OH试验。结果表明,藿香多糖的最佳提取工艺为料液比1∶10,超声提取30min,pH值为6,可使藿香多糖的提取率高达7.50%。藿香多糖对羟基自由基有显著地清除效果,表明其有抗氧化作用。

| Abstract: | Agastache rugosa polysaccharide was extracted from the branches and leaves of Agastache rugosa by ultrasonic extraction method,and L9(34) orthogonal experiment based on material-liquid ratio,ultrasonic time and pH was tested to optimize the extraction technology.Agastache rugosa polysaccharide was also used to remove hydroxyl radical.The results showed that the best extracting technology was material-liquid ratio of 1∶10,ultrasonic time for 30 min,and pH 6.The extraction rate of polysaccharide was reached up to 7.50%.Agastache rugosa polysaccharide had antioxidant activity,and had significant scavenging effect for hydroxyl radical. |
