This article presents the results of a comparative analysis of the content of individual amino acids in the overground part of Glycyrrhiza glabra L. and Glycyrrhiza echinata L., growing in the Volgograd region. By the HPLC study, 16 amino acids (Ala, Gly, Tyr, Ser, Asp, Glu, Arg, His, Pro) were identified in the plant raw materials, among which 9 are replaceable amino acids and 7 are irreplaceable amino acids (Thr, Val, Met, Ile, Leu, Phen, Lys). At the same time, of the total content, the share of replaceable amino acids in Glycyrrhiza glabra L. is 10,09 %, and irreplaceable ones – 5,84 %. In the overground part of Glycyrrhiza echinata L., these indicators are slightly higher – 11,47 % of replaceable amino acids and 6,80 % of irreplaceable amino acids.

Medicinal plants are considered modern resources for producing agents that could act as alternatives to antibiotics in demeanor of antibiotic-resistant bacteria. The aim of the study was to evaluate the chemical composition and antibacterial activities of essential oil of Foeniculum vulgare (FV) against Pseudomonas aeruginosa and Bacillus subtilis. Gas chromatography mass spectrometry was done to specify chemical composion. As a screen test to detect antibacterial properties of the essential oil, agar disk and agar well diffusion methods were employed. Macrobroth tube test was performed to determinate MIC. The results indicated that the most substance found in FV essential oil was Trans-anethole (47.41 %), also the essential oil of FV with 0.007 g/ml concentration has prevented P. aeruginosa and with 0.002 g/ml concentration has prevented B. subtilis from the growth. Thus, the research represents the antibacterial effects of the medical herb on test P. aeruginosa and B. subtilis. We believe that the article provide support to the antibacterial properties of the essential oil. The results indicate the fact that the essential oil from the plant can be useful as medicinal or preservatives composition.

Alcoholic extracts of medicinal plants Cinnamomum zeylanicum Blume, Glycyrrhiza glabra L, and Azadirachta indica A. Juss were subjected to the evaluation of antioxidant properties and combined for the cream formulation. The antioxidant property was determined by using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay and inhibition of lipid peroxidase assays. The cream formulation was designed using Minitab software and a central composite design was used to study the effect of dependent variables, steric acid and cetyl alcohol on the response variables such as, viscosity, pH, and spreadability. The phytochemical screening of extracts showed the presence of tannin, phenol, flavonoids, saponins, and alkaloids. Antioxidant properties of the extracts and their relative composition were found variable. Composition F3 (C. zeylanicum Blume: G. glabra L: A. indica A. Juss; 01: 02: 01) possessed the highest antioxidant capacity compared to other ratios. The cream prepared from this composition was found stable for pH, viscosity as well as antioxidant activity under normal condition (25) and accelerated condition (40 ). The cream with DPPH scavenging activity of 93.86 % at 15 µg/mL (IC50 8.58±0.30) and lipid peroxidase assay 90.93 % at 200 µg/mL (IC50 72.30±0.60) with pH 5.50 was found with a non-Newtonian positive thixotropic flow property. Parameters like pH, viscosity, and spreadability of the cream were within the acceptance range, and found stable and permeable
