Cytotoxicity testing of the fruit extracts of Rauvolfia tetraphylla L. using the Allium cepa chromosome aberration assay

In the present study, Allium cepa root tip was used to evaluate the cytotoxicity of Rauvolfia tetraphylla L. fruit extract. For this the root tips were treated with fruit extracts at different concentrations. The mitotic indices of control and treatments were calculated and the chromosomal aberrations were also studied. The study revealed that the fruit extracts of Rauvolfia tetraphylla at different concentration has significant effect on mitotic index and can induce chromosomal aberrations.
