Abstract
Aim: the aim of the research is a pharmacological study of the original extracts of corn silk. Materials and methods. The object of the study were 4 original extracts of corn silk, obtained by extraction with water and ethanol of different concentrations, namely: aqueous extract of corn silk (ACSE), extract of corn silk, extracted with ethanol 30 % (ECSE 30 %) , extract of corn silk, extracted with ethanol 50 % (ЕCSЕ 50 %), extract of corn silk, extracted with ethanol 70 % (ЕCSЕ 70 %). A screening study of the antioxidant properties of corn silk extracts was carried out in vitro using models of spontaneous and ascorbate-induced lipid peroxidation (LPO) in rat liver homogenate. Results. As can be seen from the given data, ECSE 50 % at a dose of 20 mg/kg showed a pronounced protective effect on the hepatotoxicity of TСM. Its use led to a probable restoration of the bile-forming function of the liver against the background of tetrachloromethane hepatitis: in response to an increase in the cholesterol content (by 43 %, p<0.05), the content of bile acids increased 2 times (p<0.05), as a result of which cholate -cholesterol ratio approached the level of indicators of intact animals, the rate of bile secretion normalized. Based on the analysis of the results of the study, it can be concluded, that in terms of bile-forming and choleretic activity on the tetrachloromethane hepatitis model, ECSE 50 % was not inferior to silibor and superior to quercetin (р<0.05). Conclusions. Biologically active substances of corn silk affect not only the diffusion and filtration processes of the liver parenchyma, but also the biosynthesis and transport of its organic components, that is, they affect the bile-forming function
