Evaluation of the biosafety potentials of methanol extracts/fractions of Tapinanthus bangwensis and Moringa oleifera leaves using Allium cepa model.

ABSTRACT: Medicinal plants are considered two-edged swords. They are pharmacologically beneficial and sometimes toxic when abused. The health benefit of medicinal plant is due to their abundant phytochemical endowment. The present study is aimed at evaluating the biosafety potentials of methanol extracts/fractions of Tapinanthus bangwensis (T. bangwensis) and Moringa oleifera (M. oleifera) leaves using Allium cepa (A. cepa) model. Cytotoxicity assay was carried out by A. epa model. The cytotoxicity parameters studied were number of dividing cells, percentage mitotic index (% MI), root tip growth length and chromosomal aberrations. The phytochemistry was determined by UV-spectrophotometry while 2,2-diphenyl-1-picrylhydrazine (DPPH) and nitric oxide (NO) were used to assay antioxidant activity. The A.
