초록

노루궁뎅이 버섯 균사체를 인진쑥 배지에 배양시킨 배양물(HEAC)을 여러 농도의 에탄올-물의 용액으로 추출하고, 쥐에서 위염 유발시약(0.15 M 염산-에탄올 용액)에 의한 위점막 손상에 대하여 추출물들의 위염 억제효과실험을 실시하였다. 그 중 80% 에탄올 추출물은 위염에 대하여 67.7%로 우수한 억제효과를 나타내었다. 용매별 분획으로 HEAC의 80%에탄올 추출물을 노르말 헥산, 염화메틸렌, 초산에틸, 노르말 부탄올과 증류수를 이용하여 5가지 분획으로 분리하였다. 그 결과, 노르말 헥산과 염화메틸렌 분획들이 위염에 대하여 우수한 억제효과를 나타내었다. 이에 따라 염화메틸렌 추출물에 대하여 GC/MS, HPLC, IR and NMR($^1H$, $^{13}C$)을 이용하여 생리활성 주성분의 구조를 확인한 결과 ethyl linoleate임을 확인하였다. 또한, HEAC의 80% 에탄올 추출물과 ethyl linoleate의 $ED_{50}$값이 각각 22.6과 6.4 mg/kg을 나타내어 대조약제인 stillen (44.2 mg/kg)과 selbex (46.5 mg/kg) 보다 우수한 억제효과가 있음을 확인하였다. 그러므로, HEAC의 80% 에탄올 추출물과 ethyl linoleate는 염산-에탄올에 의하여 유발된 위염에 대하여 우수한 억제효과를 가지고 있으며, 새로운 위염, 위궤양 치료제로 개발될 수 있을 것으로 기대된다.

The purpose of this study is to evaluate the gastric mucosal damage effect by Hericium erinaceus cultibated with Artemisia capillaris (HEAC) with 0.15 M HCl in ethanol in rats. Among them, 80% ethanol extract showed potent inhibitory effect (67.7%) on gastritis. Using solvent fractionation, 80% ethanol extract of HEAC was separated into five fractions with $n$-hexane, methylene chloride, ethyl acetate, $n$-butanol and water. As a result, fractions obtained with methylene chloride exhibited strong inhibitory effects on gastritis. With this result, the methylene chloride extract was analyzed by GC/MS, HPLC, IR and NMR($^1H$, $^{13}C$) to identify primary active components and the main component in the extract was identified as ethyl linoleate. The effective does ($ED_{50}$) values of 80% ethanol extract of HEAC and ethyl linoleate showed 22.6 and 6.4 mg/kg, respectively and these values were higher than those of stillen (44.2 mg/kg) and selbex (46.5 mg/kg). Therefore, the administration of 80% ethanol extract of HEAC and ethyl linoleate have a strong protective effect agasint the gastritis induced by HCl-ethanol and may be promising new drug for treating gastritis and gastric ulcer.
