Annotatsiya
Introduction. Biologically active food supplements based on local medicinal plant raw material play an important role in overcoming vitamin deficiency, and herbal teas are a promising dosage form of such products. Aim. To assess the quality of the “MULTIVIT” herbal tea supplement by organoleptic, physicochemical, microbiological and safety parameters and confirm compliance with the current regulatory documentation. Methods and materials. The object was a five-component “MULTIVIT” herbal tea of rosehip and sea buckthorn fruits, nettle leaves, blackcurrant leaves and fruits, and calendula flowers. Quality was evaluated by the general chapters of the State Pharmacopoeia. Results. Fine particles amounted to 1.0 %, metal-magnetic impurities 0.0005 g/kg, moisture 9.5±0.4 %, total ash 7.1±0.2 %, acid-insoluble ash 0.05 %, extractives in 70 % ethanol 21.8±3.8 %. Vitamin C was 17.09±1.2, vitamin P 17.3±2.6, vitamin B2 0.03. Foreign impurities, pathogens, heavy metals, pesticide residues and radionuclides were not detected. Conclusion. The organoleptic, physicochemical, microbiological and safety parameters complied with the regulatory requirements; the vitamin P content was slightly below the declared value but fell within the confidence interval. The data provide a scientific basis for standardization and industrial-scale production.
