Genoprotectivity of Methanol and Ethanol Extracted Leaf Sap of Trigonella Foenum-Graecum in Allium Cepa Root Assay


Fenugreek (Trigonella foenum-graecum) of Fabacecae family is widely distributed throughout the world and used as an old medicinal plant and traditional food. The present study deals with the investigation of the anti-genotoxic potential of methanol (MTG) and ethanol (ETG) extracted leaf sap of fenugreek on Allium cepa root tip cells, which were treated with cadmium sulfate (CdSO4). Three types of treatments were applied. First, roots were treated with different concentrations of methanolic and ethanolic extracts (0.1%, 0.5% and 1%) separately for 3 h each, followed by CdSO4 treatment (at 250 ppm, for 3 h). Second, roots were first treated with CdSO4 followed by extracts treatment. Third, root tips were treated with CdSO4 with extracts treatments at the same time. For controls, roots with CdSO4 (250 ppm) and distilled water served as positive and negative control, respectively. The results showed that the methanol and ethanol extracts of fenugreek modulated the genotoxic and clastogenic aberrations, which were induced by CdSO4. The protection activity of MTG (1%) was 50% in the first treatment, 70% in the second treatment and 82% in the third treatment and 61%, 68% and 88% of ETG (1%), respectively. DNA rearrangements were also observed by revealing new RAPD bands in the total DNS samples isolated from Allium roots after treatmenst.
