Abstract

The effects of whole plant extracts of Croton hirtus on cytotoxicity and some biochemicals of Allium cepa were investigated at different concentrations. The abnormalities noticed were both clastogenic and non-clastogenic types. The frequency of chromosomal abnormalities showed an increase in trend with increase in concentration of the extract however mitotic index, concentration of buffer soluble proteins and catalase activity were decreased as the concentration of the extracts increased.
