Toxic and genotoxic effects of aqueous extracts of Polygonum weyrichii Fr. Schmidt on the Allium test taken as an example
Keywords:Allium test, Polygonum weyrichii, oxidative stress, aqueous extract, flavonoids
The plant Poligonum weyrichii Fr. Schmidt is a promising plant in Murmansk region because it is a valuable source of flavonoid compounds. The aim of the study is to investigate, using a sensitive and the well-established Allium test, toxic and genotoxic effects of aqueous extracts of inflorescences and leaves of the middle tier, which differ in concentration (20, 50, 80 and 100%). According to the observations, aqueous extracts of inflorescences and leaves of P. weyrichii of 50%, 80% and 100% concentration have a mitodepressive effect on the cells of the root meristem of Allium cepa L., and inhibit the root growth, causing chromosomal abnormalities. The further investigations are necessary on selection of aqueous extracts concentrations of P. weyrichii.
