Effect of volatile organic compounds on Festuca arundinacea Schreb. lipid peroxidation

The article presents the results of determining the activity of lipid peroxidation (LPO) in biological membranes of the reed fescue Festuca arundinacea Schreb. plants in an experiment on the processing of leaf blades with different amounts of volatile organic compounds (pentane, hexane, benzene, o-xylol, benz(a)pyrene, butylacetate and their mixtures). Taking into account the dynamics of the content of malonic dialdehyde – of a stable product of LPO, it was established during the experiment that the effect of benzene, o-xylol, butyl acetate and all mixtures caused a more significant increase LPO in 1 day after treatment compared to 3 days of the experiment. At the same time, o-xylene and a mixture of pentane, hexane, and benz(a)pyrene exerted the most intense effect on the processes of LPO in comparison with other compounds. After 3 days, the amount of malonic dialdehyde changed more intensively compared to 1 day after treatment with pentane, hexane and benz(a)pyrene, and pentane and hexane caused more pronounced differences compared to benz(a)pyrene.
