ABSTRACT

The history of medicinal plants is associated with the evolution of civilization.
In all regions of the world, the history of nations shows that these plants have always occupied an important place in medicine, in cosmetic products, and culinary preparations.
The paper aims to determine the total polyphenols in different parts of the species Lysimachia nummularia L.
In our study, we focused on the extraction of polyphenolic compounds in different solvents.
The solvents used in the extraction were: 40% ethanol, concentrated methanol, in water.
The total polyphenol content was determined by spectrophotometric methods, a method from the European Pharmacopoeia 10.0, with minor modifications.
The total polyphenol content of different extracts varied depending on the extraction process.
Different parts of the plant and different solvents were used in the determinations carried out to establish the optimal extraction method for the organs of Lysimachia nummularia L.
