雪莲果SOD不同环境下活性研究

Study on determination of SOD activity of Yacon

以雪莲果为原料,采用氮蓝四唑法测定SOD的活性,研究发现,提取温度、环境温度、耐高温性、介质p H、乙醇处理和不同金属离子对SOD的活性有一定的影响,而紫外光对SOD的活性影响较少,反映了SOD对反应介质的依赖关系。SOD对雪莲果的抗氧化作用有十分重要的影响。

Took Yacon as raw material, SOD activity was measured using the tetrazolium method, the study foundthat, the extraction temperature, ambient temperature, high temperature, medium pH, ethanol and various metalions had effect on SOD activity to a certain extent, UV and impacted less on the SOD activity, reflecting the SODdependence of the reaction medium. SOD has a very important influence on the antioxidant effect of yacon.
