- 摘要:
- 为研究地黄不同部位乙醇浸提物的抗氧化活性能力,采用DPPH法、过氧化氢清除法、还原能力测定法三种评价体系,研究了河北省涉县产地黄不同营养器官乙醇浸提物的抗氧化活性。结果表明:(1)地黄不同营养器官乙醇浸提物均具有抗氧化活性,在实验质量浓度范围内,随浓度的增加,其抗氧化活性不断增强,当浓度达到一定值时抗氧化活性趋于稳定;(2)地黄不同营养器官乙醇浸提物对DPPH自由基清除能力为:叶>根>茎;对过氧化氢清除能力:根>叶>茎;还原能力:叶>根>茎。
- 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.
