Abstract

Relevance. The development of herbal medicines remains relevant today. Verbena officinalis L. has a spectrum of pharmacological activity, but our interest is manifested in its ability to treat amenorrhea and anovulation in hyperprolactinemia.

The purpose of the work was to study the dopaminergic activity of the extract, fractions and dominant substances of the verbena officinalis herb.

Materials and methods. The object of the study is the verbena officinalis herb, harvested experimentally in the field of the Botanical Garden of the Federal State Budgetary Scientific Institution VILAR in 2019.

Results. The dopaminergic activity of fractions of different polarity of herb verbena officinalis was assessed. The most active absorb ethyl acetate fraction, which includes: verbenalin and verbascoside. Verbenalin has been found to have a dopaminergic effect. Dopaminergic activity of the total extract, ethyl acetate fraction and inflammation verbenalin.

Conclusions. It is expedient to develop drugs for the treatment of amenorrhea and anovulation based on a total extract standardized for verbenalin.
