Study on Antimicrobial Activity of Extracts from Fritillaria unibracteata Hsiao et K.C. Hsia and F. ussuriensis Maxim.

Antimicrobial activities of methanol, ethanol, water, and CH₂Cl₂ extracts from Fritillaria unibracteata Hsiao et K.C. Hsia and F. ussuriensis Maxim. were investigated by disk-agar diffusion method. The result showed comparatively strong antimicrobial activity against several microorganisms. The extracts from F. unibracteata and F. ussuriensis dosedependently increased the activity. However, water and CH₂Cl₂ extracts showed no antimicrobial activity against 7microorganisms. Especially, against the most sensitive microorganism Staphylococcus epidermidis, methanol extracts at highest concentration of 20 mg/mL exhibited the largest clear zone on plate by 6-12 mm and ethanol extracts on plate by 6-10 mm.
