STUDY OF THE DYNAMICS OF REPRODUCTION OF M. LEPRAE UNDER THE CONDITIONS OF APPLICATION OF ANISEED LOFANT EXTRACT OBTAINED FROM SUPERCRITICAL FLUID EXTRACTION METHOD

One of the ways to solve the problem of drug resistance in the therapy of infectious diseases is to develop herbal preparations with high antibacterial activity, which have a good drug safety profile, is extremely significant for long-term therapy, the use of which could complement and improve the used combination therapy regimens. The aim of our study was to study the anti-leprosy activity of lofant anise extract obtained by supercritical fluid extraction using CO2 containing phenolic compounds such as gallic acid, coumarin, umbelliferon, luteolin, quercetin, taxifolin, rutin. Materials and methods. The anti-leprosy activity had been studied on Shepard's model. Blood parameters were examined on a SYSMEX XT – 2000i hematological analyzer (Japan). Conclusion. Lofant anise extract, obtained by supercritical fluid extraction using CO2, has a bacteriostatic effect on M. leprae, which is not only comparable to the effect of dapsone, but also with a more prolonged course exceeding it. Unlike the drug of choice (dapsone), the extract, when administered for 30 days, does not cause changes in red blood parameters and does not cause neutropenia. The identified effects actualize further research of the extract for the development of dosage forms based on it for practical health care.
