초록

오미자 에탄올 추출물의 항미생물 활성을 측정하기 위하여 세균, 효모, 곰팡이가 포함되는 12종류의 미생물에 대한 항미생물 활성을 측정하였다. 추출물은 세균의 생육을 억제하지만 효모와 곰팡이의 생육은 억제하지 못하였다. B. subtilis와 S. aureus에 대한 최소치사농도는 1.6~3.2 mg/mL이었으며, E. coli를 비롯한 gram음성 세균의 최소치사농도는 6.3~12.5 mg/mL이였다. B. subtilis와 S. aureus의 생육은 각 각 900 ppm과 300 ppm에서 억제되었으며 gram음성 세균의 생육은 2,000 ppm 첨가시 4시간 정도 생육이 억제되었다. 오미자 추출물의 항균활성은 열처리에 안정하였으며 부위에 따른 추출물의 항균활성은 오미자 과육의 추출물이 주로 항균력을 나타내는 것으로 나타났다.

This research was conducted to investigate the antimicrobial activities of ethanol extracts from omija against the 12 icroorganism including bacteria, yeast and mold. The extracts inhibited the growth of bacteria, but not yeast or mold. Minimum bactericidal concentration (MBC) of B. subtilis and S. aureus was 1.6~3.2 mg/mL, and those of gram(-) bacteria, including E. coli, were 6.3~12.5 mg/mL. Growth of B. subtilis and S. aureus were retarded by adding 900 ppm and 300 ppm of ethanol extracts. Anthimicrobial activity of the ethanol extracts was not destroyed by heating. In comparison of endocarps extracts with the ethanol from the seed extracts, the ethanol extracts of endocarps showed the high antimicrobial activity.
