贺兰山三种丝膜菌抗氧化活性的研究
Study on the anti-oxidant activity of three species from Cortinarius genus in Helan Mountain
摘要
Abstract
In order to evaluate the antioxidant activity ofCortinariusclaricolor,CortinariuscollinitusandCortinariusmultiformis, the fruiting bodies of the threeCortinariuswere used as material and extracted with ultrasonic methanol,and the extracts were partitioned with petroleum ether,EtOAc and BuOH successively,then the total antioxidant activities of the extracts were evaluated. The results showed that the total antioxidant activities of EtOAc extracts were higher at the same concentration levels compared with others .So, the ability to scavenge DPPH free radical , hydroxyl free radical and superoxide free radical of EtOAc extracts were evaluated , the results showed that EtOAc extracts ofCortinariusmultiformishad highest activities against free radicals of DPPH and hydroxyl, IC50 is 0.786 g/L and 1.459 g/L ,and EtOAc extracts ofCortinariuscollinitushad highest activities against free radicals of superoxide, IC50 is 0.597 g/L. The results provided theoretical basis for the further separation of antioxidant active components from theCortinarius.关键词
