  • Published : 2005.04.30

Abstract

Antibacterial, antifungal, anticancer and angiotensin-converting enzyme (ACE) inhibitory activities of water and 70% ethanol extracts of 32 medicinal herbs species were investigated. Terminalia chebula extracts showed strong antibacterial activities. Ethanol extract of Cinnamomum cassia showed good antifungal activity. ACE inhibitory activities or P. corylifolia water extract and Fraction I of P. corylifolia water extract were 65.2 and 81.8%, respectively. Cytotoxicity of ethanol precipitate fraction obtained from water extract of Eugenia caryophyllata was highest.

본 연구에서는 32종 생약재로부터 70% 에탄올과 물 추출물을 제조하고, 이들의 항균, 항곰팡이, 항암, 항고혈압활성을 조사하였다. 생약재외 추출물 제조는 32종의 생약재를 100에서 2시간동안 추출한 후 동결 건조하였다. 항균활성은 6종의 병원성 미생물을 사용하여 32종 생약재의 물 추출물과 70% 에탄올추출물에 대해 조사하였다. 그중 가자의 물 추출물과 70% 에탄올 추출물을 $125{\mu}g$ 첨가했을 때 14mm 이상의 항균 억제환을 나타내어 가장 좋은 항균활성을 보였다. 항곰팡이 활성은 5종의 곰팡이를 사용하여 32종 생약재의 물 추출물과 70% 에탄올추출물에 대해 paper disc확산법으로 조사하였다. 그 결과 계피의 70% 에탄올추출물을 $1000{\mu}g$ 첨가했을 때 10mm이상의 항균 억제환을 보여 가장 좋은 항곰팡이 활성을 나타내었다. 32종의 생약재 물 추출물과 70% 에탄을 추출물에 대한 ACE저해 활성을 조사하였다. 그 결과 파고지의 물 추출물이 10mf/mL의 농도에서 65.2%의 억제율을 나타내었으며, 파고지의 물 추출물로부터 sephacryl S-300 컬럼으로 분획한 Fr I의 분획물이 5mg/mL의 농도에서 81.1%의 억제율을 나타내었다. 생약재의 물 추출물과 70%에탄올 추출물의 세포독성을 조사하였다. 선정된 6종의 생약재중 정향의 에탄올 침전분획이 암세포에 대해 가장 우수한 세포독성을 나타내었다.
