| 摘 要： | 用乙醇有效提取马齿苋、鱼腥草、甘草、野菊花、葛根、桑叶中的黄酮,用比色法测定黄酮含量;用湿法消化提取6种药食植物中的铁元素,采用原子吸收光谱法测定其中铁的含量;对6种药食植物DPPH自由基的清除作用与黄酮和铁的含量的相关性进行了研究。结果表明:6种药食植物中都含有一定量的黄酮和铁元素,且DPPH自由基的清除作用与黄酮和铁元素含量也存在一定的相关性。

| Abstract: | The flavonoids were extracted effectively from purslane,houttuynia,glycyrrhiza,wild chrysanthemum,pueraria,mulberry leaves,the flavonoids content is determined with colorimetric method;Iron element of the six kind of medical and edible plants were extracted with wet digestion method,and the iron content was determined with atomic absorption spectrometry;Researched the correlation of scavenging effect of DPPH free radicals and flavones/iron content of the plants. The results showed the six medical and edible plants all contain a certain amount of flavonoids and iron, and the scavenging effect of DPPH free radicals has a certain correlation with flavonoids and iron content. |
