[CONTENT OF OXIDATIVE STRESS MARKERS IN BLOOD PLASMA UNDER THE ACTION OF EXTRACTS OF GRATIOLA OFFICINALIS L., HELICHRYSUM ARENARIUM (L.) MOENCH, AND ANTHOCYANIN FORMS OF ZEA MAYS L].

The effect of aqueous solutions of dry ethanol extracts of Gratiola officinalis L., Helichrysum arenarium (L.) Moench, and anthocyanin forms of Zea mays L. on the dioxidin-induced lipid peroxidation in blood has been studied on rats. It is established that all these extracts are capable of reducing the amount of avera- ge-mass (AM) molecules and malonic dialdehyde (MDA) in rat blood plasma. The extract of Gratiola officinalis L. reduces the concentration of AM and MDA moleules by 43%. The extract of Helichrysum arenarium (L.) Moench reduces the concentration of AM molecules on the average by 18.66% (within 9.22 -34.81%) and MDA by 49.36% (within 34.12-79.75%). The Extract of anthocyanin forms of Zea mays L. does not reduce the concentration of AM mo- lecules, but reduces the amount of MDA in the blood of rats on average by 27.88% (within 21.58-37.82%) (p < 0.01).
