The effects of antioxidant measured by DPPH radical scavenger activity, the extract of harvestry in July shown highest activity(91.8±0.01%). The all extracts of 4 parts(leaf, f1ower, root, branch) of harvestry in July were shown better radical scavenger activity than BHT(89.2±0.01%). The antibacteria activity of Agrimonia pilosa extracts was determined by using a paper disc method against bacteria, the methanol extracts(70%) showed the most active antibacteria activity against 12 kinds of harmful microorganisms. The methanol extracts(70%) showed the highest antibacterial activity against S. aureus and B. subtilis. In addition, the minimum inhibitory concentration(MIC) of methanol extracts(70%) against S. aureus, B. subtilis, C. diphtheriae, S. mutans, and S. epidermidis were revealed 0.625~10mg/mL. As a result, antibacteria activity in methanol(70%) extract of Agrimonia pilosa shown higher gram positive bacteria than gram negative bacteria.
