叶绿素铜钠是一种水溶性叶绿素,含有四个吡咯的卟啉类化合物与铜螯合所得,叶绿素中螯合的铜离子对肝、脾组织的呼吸有促进作用,增进血液中铁的代谢,而生产工艺中带入的游离铜,影响产品质量。浙江省药品标准(1985年)规定检查总铜和游离铜,来控制该药质量。用比色法检查游离铜,不得大于0.025％,操作繁琐,显色不太明显。
Sodium copper chlorophyll is a kind of water-soluble chlorophyll containing four pyrrole porphyrins and copper chelate obtained, the chelating copper ions in chlorophyll can promote the respiration of liver and spleen tissues, and promote the metabolism of iron in blood Production of free copper into the process, affecting product quality. Zhejiang Province Drug Standards (1985) provides for the inspection of total copper and free copper to control the quality of the drug. Colorimetric inspection of free copper, shall not be greater than 0.025%, cumbersome operation, the color is not obvious.
