Abstract

Topicality. Motherwort herb tincture is one of the most popular herbal remedies of sedative action. The disadvantage of this medicines is chemical composition volatility, and as a consequence, pharmacodynamics. Therefore, it is advisable to investigate BAS groups of Motherwort herb tincture having the greatest effect on its psychotropic activity and in the future to standardize the medicines precisely with their content.

Aim. To determine the relationship between the main BAS groups content in Motherwort herb (Leonurus cardiaca) and its psychotropic activity in order to establish the parameters of this medicine standardization.

Materials and methods. The object of the study was Motherwort herb tincture (series 15.04.16, produced at LTD “Pharmaceutical factory”, Zhytomyr region., Stanishevka v.) and the main BAS groups complexes of isolated from. Determination of hydroxycinnamic derivatives acid, flavonoids and the sum of phenolic compounds, iridoids were carried out by spectrophotometric method and HPLC method. The psychotropic activity of the research objects were studied in the open field test in the NUPh Central Research Laboratory.

Results and discussion. As a result of the chemical analysis of the tincture and obtained BAS complexes, 2 flavonoids (routine and catechin), 3 hydroxycinnamic acids (chlorogenic, coffeic and rosemarinic), 2 iridoids were identified and their quantitative contents were determined. It was established that Motherwort herb tincture and its components significantly decreases the sum of all types of psychotropic activity, mainly due to the reduction of motor activity. At the same time, it also shows a tendency to decrease the approximate research activity, indicating its sedative effect. The largest sedative activity in the smallest doses a complex of iridoids demonstrated. It should be taken into the account when this medicine is standardized.

Conclusions. The study of qualitative composition and quantitative content of the main BAS groups (flavonoids, hydroxycinnamic acids, iridoids) in the Motherwort herb tincture and dry extracts based on it. The most sedative activity was shown by substances rich in iridoids, indicating the appropriateness of standardizing  Motherwort herb tincture on the content of this particular BAS group.
