我们在检查资塔糖时,曾发现有少数不法厂商根本没有加入山道年。并因加有大量色素(多为红色)及少量脂肪类物质,以致欲检查其中是否含有山道年,甚感困难。因山道年之定性检查法,中国药典(1953年版)、英美药典,日本药局方等均用山道年对醉制氢氧化钾试液呈紫红色之反应,以及自其结晶熔点测定来铿别。如夹杂有色素及脂肪类物质,应用氯仿或苯来提取山道年时,则色素脂肪均可同时溶
When we inspected sugar towers, we discovered that a few illegal manufacturers did not join the Lunar New Year. It is very difficult to check whether or not there are mountain roads because of the addition of a large amount of pigments (mostly red) and a small amount of fatty substances. Due to the qualitative inspection method of mountain roads, the Chinese Pharmacopoeia (1953 edition), the British and American Pharmacopoeia, the Japanese Pharmacopoeia, etc. all responded to the purple-red reaction of the drunk potassium hydroxide test solution in the year of the mountain, and to determine its crystalline melting point. . If pigments and fatty substances are mixed in, when chloroform or benzene is used to extract the mountain years, the pigment and fat can dissolve simultaneously.
