Genotoxicity testing of the methanol extract of the plant Cotinus coggygria and gallic acid on Drosophila melanogaster

Abstract

The genotoxic activity of methanol extract obtained from the stem of Cotinus coggygria Scop. and synthetic gallic acid were investigated using the Drosophila sex-linked recessive lethal test (or SLRL test). In the tested methanol extract of C. coggygria (1 g), 62.50 mg of pyrocatechol equivalent of phenols was detected. Also, 46.76 mg of flavonoids and 15.75 mg of nonflavonoids were observed in 1 g of dry weight of extract. Methanol extract of C. coggygria in a concentration of 5% and 5% synthetic gallic acid were shown to be clearly genotoxic, inducing sex-linked recessive lethal mutations on the X-chromosome of Drosophila melanogaster males in all three broods.
