河北涉县产地黄乙醇浸提物的抗氧化活性研究
Study on the Antioxidan Activity of Ethanol Extracts of Rehmannia glutinosa from Shexian County of Hebei Province
摘要
Abstract
In order to study the antioxidan activity of ethanol extract of Rehmannia glutinosa for different parts,three methods of DPPH,hydrogen peroxide absorbance capacity,reducing power to determine were used to study the antioxidant activity of ethanol extracts of Rehmannia glutinosa produced in Shexian Hebei province.The results showed that the nutrient organs of Rehmannia glutinosa ethanol extracts all had antioxidant activity.The antioxidant activity increased with the increasing of concentration in the experimental concentration range,then the antioxidant activity tended to be stable when the concentration reached a certain value.The results also showed that,the nutrient organs of Rehmannia glutinosa ethanol extracts had the clearance rate on DPPH radical: leaf > root > stem,the clearance rate of hydrogen peroxide: root>leaf>stem,the reducing ability: leaf>root>stem.关键词
