Introduction: Aloe (Aloe barbadensis Miller) is the most used medicinal plant in the world. Many of its beneficial properties are due to the presence of proteins, carbohydrates, amino acids, trace elements, etc. in the gel found in its leaves. It is part of various nutritional supplements, juices, cosmetic products, etc.
Aim: The aim of the present study is to compare the elemental composition and fluorescence spectra of a natural aloe vera gel and one with different additives.
Materials and Methods: The present study investigated and compared two types of commercial products, pure aloe vera gel and aloe vera supplemented with other plant species (aloe vera &). The content of some minerals in the two products was analyzed by flame atomic absorption spectrometry (FAAS). A fiber optic spectrometer was used to measure the fluorescence spectrum of the studied samples.
Results: The emission peaks of the fluorescence spectrum of the samples are due to the content of phenolic compounds and antioxidants. Addition of honey, agave syrup, and acai puree to aloe vera gel resulted in a significant change in Mg and Fe contents, while Mn, Zn, and Cu were less affected.
Conclusion: Both tested aloe vera gel products (with and without additives) showed the presence of phenolic compounds, antioxidants, and high concentrations of magnesium.
