Abstract

The antimicrobial activity of the omija extract shown at pH 6.5, which was observed in the previous research, suggested that there could be active substances other than citric acid and malic acid in the Omija extract. Therefore, attempts were made to identify antimicrobial compounds in the essential oils extracted from Omija. The results of silica gel column chromatography and GC-MS revealed that terpineol and citronellol in the essential oil were the active compounds.

오미자 essential oil에 존재하는 항미생물 활성물질을 분리하기 위하여 hexane-ether 용매계를 이용하여 silica gel column chromatograph를 실시하였다. 여기서 얻은 6개 획분의 S. aureus에 대한 항미생물성을 조사하였고, 항미생물성이 큰 획분의 GC-MS를 통하여 9개의 성분을 동정하였다. 한편 오미자 정유, citronellol 및 terpineol을 첨가한 배지에서 S. aureus와 E. coli의 생육억제 효과를 관할한 결과 E. coli 보다는 S. aureus에 대한 항균력이 큰 것으로 나타났다. 그리고 오미자 정유를 농도별로 첨가한 배지중에서 S. aureus와 E. coli에 대한 경시적 생육억제 효과를 조사한 결과 S. aureus의 경우 오미자 정유 첨가군에서 $6{\sim}12$시간까지 생육이 억제되었으나 E. coli의 경우에는 생육억제 효과가 거의 없었다. 따라서 citronellol과 terpineol이 오미자 정유성분 중에 존재하는 중요 항균물질임을 확인하였다.
