环扁桃酸酯(Cyclandelate)的化学名为3,3,5-三甲基环己醇扁桃酸酯。它是一种选择性的脑血管扩张剂。临床主要用于动脉硬化症、脑卒中及其后遗症、脑外伤后遗症等。环扁桃酸酯在生产过程中易被空气氧化成3,3,5-三甲基环己醇苯基乙醛酸酯(简称酮酯Ketoester),因此需要对产品进行酮酯的检查。我们采用环扁桃酸酯吸收度比的方法检查酮酯的量。试验如下。一、酮酯和环扁桃酸酯的薄层分离 Cyclandelate has the chemical name 3,3,5-trimethylcyclohexanto mandelate. It is a selective cerebral vasodilator. Clinically, it is mainly used for arteriosclerosis, stroke and sequelae, and sequelae of brain trauma. Cyclic mandelate is easily oxidized by air into 3,3,5-trimethylcyclohexanol phenyl glyoxylate (Ketoester for short) during the production process, so the product needs to be examined for ketoesters. We examined the amount of keto esters using the cyclic mandelate absorbance ratio method. The test is as follows. I. Thin layer separation of keto esters and cyclomandelic esters
