硒是动物生命中所必需的微量元素,我国自东北向西南有一缺硒地带,曾引起10几个省区克山病、大骨节病等地方病严重流行。陕南紫阳是我国两个高硒区之一。本文测定了紫阳9种常见中草药的含硒量,不同种属间有明显差异,并主要集中在叶部,和正常区及缺硒区的几个对照相比,均达到不同程度的富硒水平。开发利用高硒区的富硒中草药资源,作为广大缺硒地区治病、保健的有机补硒药物,较为安全有效,能起辨证整体治疗作用,具有社会和经济双重效益。
Selenium is an essential trace element in animal life. China has a selenium-deficient zone from northeast to southwest, which has caused severe epidemics of Keshan disease and Kashin-Beck disease in 10 provinces and regions. Ziyang in southern Shaanxi is one of the two high selenium regions in China. The selenium content of nine common Chinese herbal medicines in Ziyang was determined in this paper. There were significant differences between different species and they were mainly concentrated in the leaves. Compared with several controls in the normal and selenium-deficient areas, they all reached different levels of selenium-enriched levels. . The development of selenium-enriched Chinese herbal medicine resources utilizing high selenium area is widely used as an organic selenium-enriching medicine for the treatment and treatment of selenium deficiency areas. It is safer and more effective, and can play a role in the overall treatment of syndrome differentiation, with both social and economic benefits.
