Abstract: Hyptis suaveolens and Leucas indica, two common weeds were selected for the present study, to reveal their probable cytotoxic potential. The meristematic root tips of Allium cepa were used for testing the cytotoxic property of the aqueous leaf extracts containing both polar and non-polar compounds, and that containing polar compounds alone, at different concentrations (0.125, 0.25, 0.5, 1 and 2 %) and at different time durations, using distilled water as negative control. Mitotic squash preparations were made … Show more

“…Decrease of root growth in the initial bagasse extracts can be due to the occurrence of chromosomal aberrations and reduction in mitotic activities. Sumitha and Thoppil ( 2015 ) observed that the decrease in root length of plant extracts may be due presence of some substances that impair cell expansion and differentiation of A. cepa root tip cells. Reduction of root growth in A. cepa root chromosomal aberration assay indicates cytotoxicity and growth retardation (Grant 1999 ).…”

“…Allelochemicals present in the species have been reported to act by causing oxidative stress, reduction in chlorophyll content, and inducing the formation of chromosomal aberrations [ 99 , 100 ]. Such damage may occur in response to the synergistic action of the constituents.…”

“…After 48 h, the number of roots grown/bulb was counted and further removed and measured. Bulbs with minor root growth were excluded from each group (Sumitha et al, 2016). The ends of major root grown were immersed in Carnoy's solution fixative (ethanol: acetic acid, 3:1), maintained at refrigerator for 24 h. Afterwards, two ends of each bulb were isolated and immersed in a heated HCl 1 N solution.…”
