Abstract

The bioactive compounds contained within many plants account for their pharmacological values. Aloe vera has a wide range of organic and inorganic components, including carbohydrate polymers, glucomannans, and a variety of other natural and synthetic materials. The study aims to take a look into the characteristics of some metal complexes produced from Aloe vera extracts. The extracts from Aloe vera were derived by means of acetone, distilled water and ethanol. The solubility of the metal complexes with the ligand at varying temperatures was established. FT-IR was used to carry out the infra-red examination of the ligand. The results revealed that alcoholic extract of Aloe vera leaf was not soluble in Cu, Fe, or Zn but only soluble in Fe, the extract by distilled water was soluble in Cu, Fe and Zn. However, the Aloe vera in acetone as well as in the Zn (II) and Cu (II) composites displayed a bending that was found at 1430.97 cm⁻¹, 1500.01 cm⁻¹ and 1615.90 cm⁻¹.every functional groups are assigned to be coordinating sites as a result of increase or decrease in the wave number, and absorption band. Findings from the investigation reveal that the complexion of the metal salts with diverse donor sites in the extract is indicated by an increase in the absorption peak of the functional groups in the metal composites of the extracts.

芦荟提取物中具有生物活性的植物化学物质与金属离子的配位；研究金属络合物和形成的生物活性化合物。

许多植物都含有生物活性化合物，因而具有药理价值。芦荟中含有多种有机和无机成分，包括碳水化合物聚合物、葡甘露聚糖以及其他多种天然和合成材料。本研究旨在了解芦荟提取物产生的一些金属复合物的特性。芦荟提取物通过丙酮、蒸馏水和乙醇提取。确定了金属配合物在不同温度下与配体的溶解度。使用傅立叶变换红外光谱对配体进行了红外检测。结果表明，芦荟叶的酒精提取物不溶于铜、铁或锌，只溶于铁；蒸馏水提取物可溶于铜、铁和锌。然而，丙酮中的芦荟以及锌（II）和铜（II）复合材料中的芦荟在 1430.97 cm-1、1500.01 cm-1 和 1615.90 cm-1 处显示出弯曲。研究结果表明，萃取物中具有不同供体位点的金属盐的复合性表现为萃取物金属复合材料中官能团吸收峰的增加。

期刊介绍： BioMetals is the only established journal to feature the important role of metal ions in chemistry, biology, biochemistry, environmental science, and medicine. BioMetals is an international, multidisciplinary journal singularly devoted to the rapid publication of the fundamental advances of both basic and applied research in this field. BioMetals offers a forum for innovative research and clinical results on the structure and function of: - metal ions - metal chelates, - siderophores, - metal-containing proteins - biominerals in all biosystems. - BioMetals rapidly publishes original articles and reviews. BioMetals is a journal for metals researchers who practice in medicine, biochemistry, pharmacology, toxicology, microbiology, cell biology, chemistry, and plant physiology who are based academic, industrial and government laboratories.
