准确地分析和定量胎盘制剂中脂溶性维生素,对了解其生化和药物性质是十分必要的。用高效液相色谱法分析与定量脂溶性维素已有报道。这种方法快速、简便,回收率可达95 ％以上,优于目前常用的其他方法。本文采用反相高效液相色谱法对胎盘制剂中四种脂溶性维生素进行了分离及定量测定。一、方法仪器:日立635 A高效液相色谱仪,检测
Accurate analysis and quantification of fat-soluble vitamins in placenta preparations is essential to understand their biochemical and pharmacological properties. High performance liquid chromatography for the analysis and quantification of fat-soluble fibrin has been reported. This method is fast and easy, and the recovery rate can reach more than 95%, which is better than the other methods commonly used at present. In this paper, reversed-phase high performance liquid chromatography in placenta preparations of four fat-soluble vitamins were isolated and quantitative determination. First, the method of equipment: Hitachi 635 A high performance liquid chromatography, detection
