Mutagenic and antimutagenic effects of aqueous extract of rosemary (Rosmarinus officinalis L.) on meristematic cells of Allium cepa.
Polyphenolic compounds present in rosemary were found to have antioxidant properties, anticarcinogenic activity, and to increase the detoxification of pro-carcinogens. The aim of the study was to determine the effect the aqueous extract of rosemary (AER) on mutagenicity induced by methylmethane sulfonate in meristematic cells of Allium cepa, as well as to describe its mode of action. Anti-mutag...
متن کاملEffects of the flower extract of Ixora coccinea Linn. On the meristematic cells of Allium Cepa
The aqueous extract of flowers of I. coccinea was evaluated for its cytotoxic and mutagenic effects on the meristematic cells of onion root tip. The percentage of abnormalities was found to increase with the increase in the concentration of the extract from 20 to 60 mg/ml. With 80 mg/ml completed arrest or total inhibition of cell division was observed. The major abnormalities were unprinted ch...
متن کاملAction of aqueous extracts of Phyllanthus niruri L. (Euphorbiaceae) leaves on meristematic root cells of Allium cepa L.
This study aimed to evaluate the effects of aqueous extracts of dried Phyllanthus niruri L. (stonebreaker) leaves on Allium cepa L. root meristem cells at four concentrations, 0.02 (usual concentration), 0.04, 0.06 and 0.08mg/mL and exposure times of 24 and 48 hours. For each concentration we used a group of five onion bulbs that were first embedded in distilled water and then transferred to th...
متن کاملCytological Effects of Blitox on Root Mitosis of Allium cepa L
The genotoxic potential of blitox (fungicide) was investigated by using chromosome aberration in Allium cepa root tip cells. Allium cepa roots were treated with 2g/lt., 3g/lt. and 4g/lt. concentrations of blitox and distilled water as control at 4 hours, 8 hours and 12 hours duration. The results indicated that blitox significantly increased the genetical abnormalities at all concentrations and...
متن کاملCytological Effects of 5- Amino Uracil on Allium cepa L. roots
5Amino Uracil is a structural analogue of pyrimidine. In this work the cytological effects of 5-AU has been evaluated in the root tip cells of Allium cepa L. following treatment with different concentrations for different durations. Microscopical observation of the cells revealed that 5-AU has considerable clastogenic activities as evidenced by altered MI (Mitotic index) values as well as occur...
