Ethanolic, chloroformic and aqueous extracts of each plant were obtained by soxhlet apparatus. Chloroformic extracts were dissolved in cell culture media with the help of Dimethyl sulfoxide (DMSO). Eight concentrations 1 µg/ml, 6 µg/ml, 12 µg/ml, 25 µg/ml, 50 µg/ml, 100 µg/ml, 200 µg/ml and 400 µg/ml of each plant were used for both assays. Confluent BHK - 21 cells were grown in 96 well cell culture plates. Cells were treated by each concentration of extracts and extracts containing FMDV for cytotoxic and antiviral assay respectively in triplicate manner. Positive control (BHK-21 cells & cell culture media) and negative control (BHK-21 cells, FMDV & cell culture media) were kept for antiviral assay. For cytotoxic assay, positive and negative controls were kept as BHK-21 cells plus media and BHK-21 cells, media plus DMSO (20%) respectively. Cells viability and cytotoxic activity were determined by MTT assay for antiviral and cytotoxic assay respectively. Each extract was analyzed as cell survival percentage and expressed as means ± S.D. Statistical analysis was carried out by ANOVA. Seven plants extracts out of nine, exhibited antiviral activity against FMDV at a concentration non toxic to BHK-21 cell line. Ethanolic AI extract showed strongest anti-FMDV activity. Chloroformic MO leaves extracts showed significant antiviral activity. Chloroformic and aqueous MA leaves extract had no remarkable antiviral activity. At higher concentrations most of the plant extracts were cytotoxic
