This study was carried out to investigate the efficacy of antifungal and antibacterial activity of Veratri Herba, which was used as insecticide in the clinical part of oriental dermatology for a long time. Sample herb was selected with Veratrum maackii in the middle of 5 veratrum species. The experimental results of this herb were as follows. Crude extract showed various relative inhibitory rates from 68.9% to 95.6% in 2mg/disc against Fusarium oxysporum, Botrytis cineria, Saccharomyces cerevisiae, Escherichiae coli, and Bacillus subtilis on the basis of inhibitory range against B. cineria, and the inhibitory effect was decreased depending on density. In the extract of various organic solvent, chloroform and ethyl acetate fraction show the various size of dear zone against all microbes. And in the subfraction assay from ethyl acetate fraction, crude alkaloids show the antibacterial and antifungal effect significantly.
