Description
Summary:Low meadow-rue (Thalictrum minus L.) antioxidant complex was studied in cell extracts and culture medium. Its activity was expressed as total polyphenol content in ferulic acid equivalents. In these model systems (cell extracts and culture medium) the inhibition of lipid oxidation and diphenylpicrylhydrazine reduction (EC50 = 12–15 μg/ml) were observed. At the phenolic compound concentration of 8–15 μg/ml, the reducing capacity of cell extracts was equivalent to 1.5 mM ascorbic acid. At the same time, berberine, a major alkaloid synthesized by the culture, manifested a low antioxidant activity. The analysis of phenolic acid composition in low meadow-rue showed that one of the main components of its antioxidant system were caffeic, gallic, chlorogenic, and ferulic acids.
