Background: The aim of this work is pharmacognostic study of herbal formulation consisting of elecampane rhizomes and roots (Inula helenium L.), fruits of rose (Rosa sp.) and hawthorn (Crataegus sp.), leaves of pepper mint (Mentha piperita L.) and cowberry leaves (Vaccinium vitis-idaea L.), spiny eleuterococcus rhizomes and roots (Eleutherococcus senticosus (Rupr.et Maxim.) Maxim., low cudweed herb (Gnaphalium uliginosum L.s.l.) as well as determination of its hepatoprotective activity. Materials and methods: An electron microscope, HPLC and methods of the State Pharmacopoeia of Russia were used in pharmacognostic study of herbal formulation. The hepatoprotective, antioxidant and choleretic activities of the herbal formulation were studied in vivo model of liver damage induced by tetracycline hydrochloride and 40\% ethanol. Results: The content of biologically active substances (BAS) collected: essential oils - at least 0.30\%; flavonoids in terms of luteolin - not less than 1.0\%; ascorbic acid - not less than 0.5\%; tannins - not less than 3.0\%; arbutin - at least 0.4\%; eleutheroside B - not less than 0.01\%.It has been found that the course administration of herbal formulation to white Wistar rats with liver damage eliminates the prooxidant effect of tetracycline and ethanol, reduces the manifestation of cholestasis and increases the rate of bile secretion for 1-3 hours. Conclusion: The herbal formulation has hepatoprotective activity, antioxidant, choleretic effect and stimulates regenerative and antitoxic processes in the liver in rats with a model of combined liver damage induced tetracycline and ethanol. The obtained research results argue the possibility of using herbal formulation for prevention and complex treatment of liver diseases.

The popular use of natural products has great benefits for the health of the human population. In this study we highlight Equisetum hyemale, belonging to the phylum Sphenophyta and the family Equisetaceae. Popularly, the stems of this plant are used for their diuretic, digestive, anti-anemic, and anti-inflammatory properties. Given this context, and the fact that the growth of antimicrobial resistance is a serious problem for global public health, this plant could be used as an alternative, to increase our therapeutic arsenal. Therefore, it is important to more clearly elucidate the complex structures present in plants, because these substances are mainly responsible for their beneficial and/or toxic effects. Thus, the objective of this study was evaluate the antimicrobial activity, cytotoxic and genotoxic potential of the phenolic compounds separately. The substances luteolin, ferulic acid and coumarin were identified at high concentrations by ultra-high performance chromatography-electrospray ionization-mass spectrometry (UPLC-ESI-MS). Antimicrobial activity was elucidated through microdilution in broth; the phenolic compounds were able to inhibit the visible growth of the standard bacterial strains at low concentrations. Cytotoxicity was evaluated by MTT and genotoxicity was analysed through cellular damage using a Comet assay; the results showed that it did not present cytoxicity or genotoxicity at the corresponding concentrations. With this, we suggest that E. hyemale may be an alternative for the treatment of infections by microorganisms that are resistant to synthetic drugs.
