环糊精及其衍生物在手性药物分离中的应用

手性药物的对映体由于空间结构不同,在生物体内结合的受体不同,导致其在药理和药效上有很大的差异,因此对手性药物进行手性拆分分析研究有着非常重要的现实意义.本文综述了2000年来环糊精及其衍生物作为手性流动相添加剂在高效液相色谱法中分离手性药物的应用情况.     

当归麻口病的病因研究

本文确定了当归麻口病病灶及其附近有包括50余种生物的土壤复合体,形成一个土壤生物食物网。对食物网成员关系作了新的补充。证实了燕麦镰刀菌等6种真菌是病原菌,是直接病因,地下害虫、人为和机械创伤形成的伤口有利于病原菌的侵染,无脊椎动物携带病原菌并参与为害,而更加导致该病的严重发生.根据病因和防治试验,提出一套综合治理措施,在甘肃推广1万4千多亩,获得了显著经济效益和社会效益。     

STUDIES ON CAUSES OF THE POCKMARKED DISEASE OF CHINESE ANGELICA

The present studies show that there is a biocommunity including 59 kinds of organisms in and around the focus of angelica pockmarked disease to form a soil food web. These results add new content to the relationship among food webmembersr~[1, 2]. The studies prove that 6 species of Fusarium are pathogenes, the wounds caused by underground insects and artificial factors are beneficial to pathogene infection, and invertebrates carrying pathogenes aggravate the disease. According to the tests, a disease control method is proposed and applied to 14, 000 mu in Gansu Province, and economic and social benefits have been obtained. The present studies are part of the state projects on technological development of agriculture, animal husbandry and fishery.
