In the present study Dichloromethane-methanol and Pet ether extracts of Euphorbia tirucalli latex were prepared and evaluated for antiviral activity against tobamo viruses viz. Tobacco Mosaic Virus (TMV) and Tomato Mosaic Virus (ToMV). Three concentrations of the respective extracts (50,100,150ppm) were taken for antiviral studies.Among the three concentrations, both Dichloromethane-methanol and Pet ether extracts showed maximumprotection at 150ppm.Dichloromethane-methanol extract showed maximumprotection (81%) than Pet ether extract against TobaccoMosaic Virus (TMV) at 150ppm, whereas Pet ether extract showed maximumprotection (80%) againstTomatoMosaicVirus (ToMV) at 150ppmwhen compared to that of Dichloromethane-methanol extract.
