| 摘 要： | 提出了一种快速测定桂皮中桂皮醛含量的方法。桂皮醛在强碱性条件下与过氧化氢发生氧化反应,生成苯甲酸和乙二酸,然后用标准硫酸溶液反滴定剩余的碱,根据消耗的硫酸的量计算出桂皮中桂皮醛的含量。此方法操作简单,准确快速,易于推广。

| Abstract: | A rapid and simple method for the determination of cinnamaldehyde content in cassia was established.In the presence of strong alkali,cinnamaldehyde was oxidized by hydrogen peroxide to form the benzoic acid and oxalic acid,the excess sodium hydroxide was then titrated using a standard solution of sulfuric acid,so the amount of cinnamaldehyde is calculated from the titer values.The proposed method is accurate,saving-time and easy to be carried out,and be applied easily and widely. |
