Ethyl acetate, chloroform, butanol and methanol extracts of the aerial parts of Conyza Canadensis L. Cronquist were investigated for their antiviral activity against human cytomegalovirus (HCMV) AD-169 and Cox-B3 viruses by modification of the widely used shell-vial assay. The results showed that butanol and methanol extracts had the most potent antiviral activity against HCMV and Cox-B3 viruses.

Key words: Conyza canadensis (L.) Cronquist, antiviral activity, human cytomegalovirus (HCMV), Coxsackie B virus type 3 (CoxB-3).
