field, this antiviral agent could protect some economically important crops against natural
infection by plant viruses. The purpose of this research is to find out the activity of our research
plant Boerhavia dWusa against cytotoxicity and microorganisms.During our research work we
did Brine shrimp lethality bioassay to measure the activity of Boerhavia diffusa by using solvent
Ethyl acetate and Potassium dichromate as Positive control.ln terms of Antimicrobial test, we
used 3 types of microorganisms - Staphylococcus aureus, Shigella dysenteriae and Candido
albicans.ln terms of first 2 micrroganisms The Ethyl acetate extract of Boerhavia diffusa showed
