AIM: The main objective of our studies was to determine the chemical composition and biological activities (antioxidant and anticoagulant properties) of two standardized phenolic fractions from sea buckthorn twig and leaf, and two standardized nonpolar fractions from twig and leaf in human plasma in vitro.
MATERIAL & METHODS: Appropriately prepared extracts from sea buckthorn twigs and leaves were used. Markers of oxidative stress and hemostasis were determined in this work.
RESULTS: The reduction of plasma lipid peroxidation induced by HO/Fe was observed for two fractions from twig. Analysis of the effect on the coagulation properties of plasma demonstrated that the nonpolar fraction from twig and the phenolic fraction from leaf, significantly prolonged the activated partial thromboplastin time and the prothrombin time, respectively.
CONCLUSION: Sea buckthorn twig and leaf are new promising plant materials in the prophylaxis and treatment of cardiovascular disorders.
