Study of qualitative composition and quantitative content of free organic acids in lingberry leaves

Actuality.Organic acids are aliphatic and aromatic compounds with carboxyl group that play crucial roles in plant metabolism.It's worth noting that all plant species, regardless of their family, contain varying amounts of organic acids, which are biologically active compounds.Aim -to identify and quantify free organic acids in lingberry leaves (Vaccinium vitis-idaea L.). 1,2023 . Materials and methods.Grinded dry lingberry leaves were used for the study.Thin layer chromatography (TLc) was employed to detect the organic acids, while the alkalimetric method was used for their quantification. . Results and discussion.A TLc technique was utilized to identify the presence of oxalic, citric, malic and tartaric acids.The total content of free organic acids is 2.030.04%,2.080.01% 3.620.13%for potentiometric, conductometric and indicator titration methods, respectively.Conclusions.Qualitative analysis and determination of the quantitative content of organic acids in lingberry leaves were performed.The possibility of using conductometric and potentiometric titration methods in preliminary studies for the quantitative analysis of free organic acids in the studied raw materials is shown, and their advantages over the indicator titration method are shown.
