Özet
<p>Humic acid (HA), fulvic acid (FA), and humin are the main fractions of the soil. Fulvic acid, which is 25-75% of the organic materials in soil, is a water-soluble fraction at all pH values. The color of FA is ranged from yellow to black. FA includes minerals, amino acids, sugars, peptides, nucleic acids, phytochemical compounds, and vitamins. In addition, it has several known properties including heavy metal chelation, antioxidant, anti-inflammatory, and antimicrobial properties as well as positive health effects for humans such as to transport some nutrients, mainly minerals, to cells and remove deeply embedded toxins from the body. Thus, FA became a new, valuable, and natural alternative material as a food additive.</p><p>Mainly two methods which are NAGOYA and IHSS were reported in order to extract FA from different sources such as leonardite, coal, lignite. In this study, the IHSS method was used with different solvents to extract FA from leonardite using to obtain different extracts of FA. High-performance liquid chromatography (HPLC), Fourier transform infrared spectroscopy (FTIR), spectrophotometric method were applied to characterize these extracts.</p>
