Evaluation of effect of different concentrations of catechu extract (Acacia catechu) on onion root system has been done. In the present study effect of catechu extract of different concentrations (0.02%, 0.04% , 0.06% , 0.08% , 0.1%) were compared with control treatment. . Results obtained indicated that the aqueous catechu extract of various concentrations showed a decrease in root length at higher concentration. Also, the various concentrations of the extracts had toxic effects on the cells, which caused general significant reduction in the mitotic index and increase in total abnormality percentage when compared with the control after 72hrs of incubation at room temperature. This study revealsed that higher concentrations of catechu extract have affected the root tips of Allium cepa resulting in chromosomal aberrations. Further investigations are recommended to ascertain the mutagenic effect of the consumption of catechu on man.
