Introduction: This research aims to determine the immunomodulating activity of chicory (Cichorium intybus L.) herb extract and to evaluate the prospects of development of the medicine based on it. Methods: Object of the research was dry chicory extract obtained from herb (aerial part) of a wild plant. The chemical composition of the extract was determined by HPLC-MS method. Its immunomodulating action has been explored in vivo experiments involving intact animals, as well as immunosuppressed animals, treated with azathioprine cytostatic agent. Chicory extract was administered at a dose of 30 mg/kg per os 1 time per day for 14 days. As a reference drug, Immunal (Lec Pharma, Slovenia) was used. Chicory extract action on the state of cell immune component was evaluated in delayed hypersensitivity reaction. The humoral immunity condition was evaluated by the count of antibody-forming cells determined by the local hemolysis method. The state of the macrophage component of the immune response was evaluated in the phagocytosis reaction of peritoneal macrophages in relation to colloid liquid ink particles. Results: Dry chicory extract is capable to reduce the suppressive azathioprine effect on the cell-mediated immune response, antibody response, and phagocytosis with macrophages; it does not change the immunity indicators in intact animals. Conclusion: Dry chicory extract contains phenolic complex of biologically active substances, namely oxycoumarins, hydroxycinnamic acids, and flavonoids. Dry chicory extract is an effective immunocorrecting agent; it should be recommended for further study and application aiming for the prevention and treatment of immunodeficiency states.

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.

Introduction: Ethnobotanical studies report that Myrcia guianensis (Myrtaceae), belonging to a group of plants known as pedr\á-ume-ca\á or insulin plant, is used as a tea to treat various diseases, including diabetes, a metabolic disorder that leads to the constant production of free radicals. The objective of this work was to determine the antioxidant capacity and the cytotoxicity of the AEMg. Methods: The content of phenolic compounds in AEMg was determined by colorimetric assays. In vitro tests of the antioxidant capacity of AEMg, in the sequestration of DPPH radicals, in \β-carotene bleaching, in the FRAP, as well as in human fibroblast cells of the MRC-5 lineage, were performed. The cytotoxic activity of AEMg was evaluated in assays with eukaryotic cells from yeast Saccharomyces cerevisiae and in PBMC. Results: The results showed that the AEMg is rich in phenolic compounds, presenting high antioxidant potential in all the tests carried out, including in human fibroblast cells of the MRC-5 lineage, besides not being toxic to eukaryotic cells. Conclusion: The AEMg, rich in antioxidant compounds and no toxicity, can be used as source of natural antioxidant in the treatment of metabolic diseases to combat free radicals.

Context: Plant from the Lamiaceae family are considered as dietary spices and medicinal herbs traditionally used in medicine for the treatment of several pathologies. Objective: Evaluation of the in vitro antibacterial activity of ethanol and aqueous extracts of nine Moroccan plants from the Lamiaceae family against six bacterial strains regularly implicated in toxiinfection. Method: The antibacterial activities of hot (HAE), cold (CAE) aqueous extracts and ethanolic extracts (EE) were evaluated using agar-well diffusion method, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and IC50 against six foodborne bacteria (Bacillus cereus, Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Salmonella enterica). Total phenolic and flavonoid contents were assessed as well. Results: In the present study, the ethanol extracts were rich in polyphenols, with middling values of flavonoids, and relatively poor in condensed tannins. The presence of saponins, essential oils, irroides, alkaloids, anthocyanins, and aldehydes was recorded. The effect of the extracts was directly bactericidal for B. cereus and L. monocytogenes; for the other strains, the MBC value was twice higher than that of MIC. However, the ethanol extract (EE) of O. majorana and T. satureioides showed the highest antibacterial activity. With the principal component analysis, it was demonstrated that the nine Lamiaceae family plants possess a powerful antibacterial effect, correlated with their phenolic content. Statistical analysis: Analysis of variance was performed by uni-varied ANOVA in the software SPSS 22 Fr. Conclusion: The active compounds were thermostable and soluble in ethanol and water. The antimicrobial activities of the plants extracts investigated may contribute to understand their involvement in traditional medicine against many microbial infections.
