Abstract:

The paper presents results of the comparative study of the iron-chelating potential and antioxidant activity of the raw material of phytopreparations and analysis of correlations between these activities and the content of phenolic compounds as the most important plant antioxidants. The total content of phenolic compounds was determined by the Folin-Chokalteu method, che-lating activity was evaluated using the ferrozine method, antiradical activity was determined by DPPH assay, and total antioxidant (reducing) capacity was assessed by the phosphomolybdenum method. A strong positive correlation

Abstract:

Phenolic compounds are the largest group of compounds that act as natural antioxidants in plants. One of the plants that has the potential as a natural antioxidant is Jotang (Sphagneticola trilobata). This study aims to determine whether jotang leaf extract (Sphagneticola trilobata) has phenolic content and to determine the total phenolic content in jotang leaf extract (Sphagneticola trilobata). Jotang leaves were extracted by maceration method using methanol solvent. The method of determining total phenolic content was carried out using Folin-ciocaltaeu reagent because phenolic compounds can
