| 摘 要： | 依据视黄醇可与三氯化锑溶液发生呈色反应生成兰色可溶性物质的原理，用比色法进行视黄醇含量的测定，该方法与常规的异丙醇溶解法测定结果对照，具有相对误差小，准确度高的特点，使用三氯化锑比色法对牛肝中视黄醇含量进行了平行测定，测定结果平均值为０．０２５３ｍｇ／ｇ，相对标准偏差为１．１９％，实验结果显示精密度良好，操作方法简便可靠，具有普遍性使用价值。

| Abstract: | Retinol was measured according to the theory that retinol could react with solution of antimony trichloride to get blue dissoluble substance and the method was compared with common determination result of isopropyl alcohol dissoluble method. The content of retinol in the liver of cattle was made parallel determination with clorimetric analysis of antimony trichloride. The average value was 0.0253 mg/g. |
