天然虫草和人工虫草菌丝体的抗氧化活性比较研究

Comparison of the antioxidant activities of natural and cultured Cordyceps

目的:通过比较生物活性,探索对天然虫草与人工虫草菌丝体的质量进行控制的方法。方法:采用邻苯三酚自氧化法和DPPH自由基清除实验来评价天然虫草与人工虫草菌丝体的抗氧化活性。结果:人工虫草菌丝体具有比天然虫草更好的抗氧化活性,抗氧化活性与虫草中含有的某些成分的含量有关。结论:抗氧化活性可以作为评价人工虫草菌丝体质量的指标之一。

Objective： To establish a method for the quality control of natural and cultured Cordyceps by comparing their bioactivity in vitro. Methods： The pyrogallicacid autooxidation method and the DPPH free radical scavenging method were used. Results： The cultured Cordyceps had higher antioxidant activity than the nature Cordyceps, the antioxidant activity was correlated to the contents of some components in the Cordyceps. Conclusion： The antioxidant activity could be one signal in the quality evaluation of cultured Cordyceps.
