:本文用紫外分光光度法测定了三种黔产淫羊藿不同部位的总黄酮含量 ,并作比较。实验表明 :各种黔产淫羊藿的根部均含有丰富的总黄酮 ;作为广布种 ,黔岭淫羊藿的药用价值似应肯定。这两项结果 ,对黔产淫羊藿的资源利用来说 ,都具有一定价值 : The content of total flavonoids in different parts of Epimedium species was determined by UV spectrophotometry and compared. Experiments show that: the roots of various species of Epimedium are rich in total flavonoids; as a widely distributed species, the medicinal value of Epimedium may seem certain. Both of these results have certain value for the use of resources for the production of Epimedium.
