近年来研究表明,黄精、首乌中主要含有多糖、蒽醌等有效成分,且很多单味中药及其多糖具有抗自由基作用[1～3]。但将有效部分提取出来,通过均匀试验设计,研究其不同组合在抗氧化酶活性方面的改变,而达到定向地改进中药提取工艺并使有效部分达到最佳组合的研究尚不多见。本实验采
Recent studies have shown that Huangjing and Shouwu mainly contain active ingredients such as polysaccharides and wolfberry, and many single Chinese herbs and their polysaccharides have anti-free radical effects [1–3]. However, the effective part was extracted, and the uniform experimental design was used to study the changes in the antioxidant enzyme activities of different combinations, and it has been rare to reach the goal of improving the extraction process of traditional Chinese medicine and making the effective part reach the optimal combination. This experiment adopts
