采用中国药典1977年版的方法鉴别葡萄糖,当药物呈色时,鉴别葡萄糖有困难,当含有还原剂时,鉴别有时成为不可能。为此,笔者参考有关资料[(?)ap-ma(?)30(1):64,1981],改用胶体硫溶液鉴定葡萄糖,经试用,本法简便易行,且较灵敏。现介绍如下:1.试剂:将0.5g 硫代硫酸钠溶解于10ml 浓硫酸中,再加浓硫酸至25ml,即得。本品为一种胶体硫溶液。2.操作方法:取葡萄糖或葡萄糖的混合物溶解于一滴水中,添加0.3ml 试剂,几分钟后呈现淡紫色-
The Chinese Pharmacopoeia 1977 version of the method of identifying glucose, when the drug coloring, identification of glucose difficulties, when containing reducing agents, sometimes impossible to identify. To this end, the author with reference to the relevant information [(?) Ap-ma (?) 30 (1): 64,1981], instead of using colloidal sulfur solution identification of glucose, the trial, this method is simple, and more sensitive. Are introduced as follows: 1. Reagents: 0.5g sodium thiosulfate dissolved in 10ml of concentrated sulfuric acid, plus concentrated sulfuric acid to 25ml, that is, too. This product is a colloidal sulfur solution. 2. Method of operation: Take a mixture of glucose or glucose dissolved in a drop of water, add 0.3ml reagent, a few minutes after the lavender -
