摘 要：
选取超声波提取法对红松树皮中多酚类物质的提取工艺进行研究,以多酚提取率作为指标,采用单因素试验及正交试验,研究了物料比、乙醇浓度、提取时间、提取温度对红松多酚提取的影响。结果表明,超声波提取的最佳工艺条件是:物料比(g·m L~(-1))1∶30,乙醇浓度60%,提取时间2.0 h,提取温度80℃。本文也对红松多酚的抗炎作用进行了研究,并与杨树多酚、蓝莓多酚进行了比较,结果表明,在0.01~100μg·m L~(-1)范围内,3种多酚都有一定的抗炎作用,且抗炎作用大小顺序为:蓝莓多酚>红松多酚>杨树多酚。

摘 要：
The ultrasonic extraction process was used to extract polyphenols in Korean pine bark,with the polyphenol yield as index. The optimum conditions were obtained through single factor test and orthogonal test with 4 factors of material ratio,ethanol concentration,extract time and extract temperature. The optimal ultrasonic extract conditions were material ratio( g·m L~(-1)) of 1∶30,ethanol concentration of 60%,extract time of 2. 0 h,and extract temperature of 80℃. For the anti-inflammatory effect of Korean pine polyphenol,polar polyphenol and blueberry polyphenol,in 0. 01- 100 μg · m L~(-1),the anti-inflammatory effect order was:blueberry polyphenol > Korean pine polyphenol > polar polyphenol.
