The production of active metal complexes as a source of micronutrients is still highly desirable. In this study, metalloporphyrin compounds (i.e., iron, magnesium, and zinc) were obtained by modifying sodium-copper chlorophyllin. Metalloporphyrins were prepared by a multi-step process involving protonation of sodium-copper chlorophyllin, followed by complexation of porphyrin with selected metal salts in a DMSO solution. The selected metalloporphyrins were analysed in terms of stability, metal content, and process yield using UV-Vis, FT-IR, and ASA methods. Analysis of the influence of the pH of the complexing system and the molar ratio of chlorophyllin and metals showed that it is possible to obtain metalloporphyrins of Mg, Zn, and Fe with metal bonding efficiencies of 20, 40, and 90%, respectively. The type of acid, its concentration, and the type of salt used in the processes were also critical factors in the protonation of porphyrin as well as the efficiency of metal-porphyrin bonding.

仍然非常需要生产作为微量营养素来源的活性金属络合物。在这项研究中，金属卟啉化合物（即铁、镁和锌）是通过改变钠-铜叶绿素获得的。金属卟啉是通过多步工艺制备的，包括钠-铜叶绿素的质子化，然后在 DMSO 溶液中将卟啉与选定的金属盐络合。使用 UV-Vis、FT-IR 和 ASA 方法对所选金属卟啉的稳定性、金属含量和工艺产量进行了分析。分析络合体系的pH值和叶绿素与金属的摩尔比的影响表明，可以获得金属结合效率分别为20%、40%和90%的Mg、Zn和Fe金属卟啉。酸的种类、浓度、
