정향의 mathanol 추출물로 HCI-ethanol 위손상 실험을 하여 그 방어 효과를 확인하고 이를 계통 분획한 후 각 분획에 대한 HCI-ethanol 위손상실험, 기초위액 분비실험, indomethancin 위손상실험, acetic acid 궤양 실험을 하여 추출물에 대한 급성독성과 급.만성위염 및 위손상에 대한 실험한 바 다음과 같은 결과를 얻었다. (1) $LD_{50}$은 경구투여시 3000 mg/Kg 이사이었다. (2)HCL.ethanol 위손상실험에서 EtOAc fr. 165mg/Kg과 BuOH fr. 215mg/Kg에서 손상의 크기를 유의성있게 감소시켰다. (3) Acetic Acid 궤양 실험에서 위궤양의크기가 BuOH 분획 215mg/Kg으로 유의성 있게 감소되었다. 이상의 결과로서 생각은 급만성 위염 및 위손상에 대한 세포보호 작용이 있으며 그 작용기전은 위액분비의 억제작용에 인한 것이며 그 유효성분은 대부분 butanol 분획에 존재하는 것으로 생각된다.

This study was perfonned to investigate effectiveness eness on the gastritis and gastric lesion with the methanol extract of the flower buds of Eugenio caryophyllata. The extract was fractionated with hexane, chIorofonn, ethyl acetate, butanol, followed by bioassay Oil antigastritis. The ethyl acetate and the buthanol fraction reduced significantly HCI.ethanol induced gastric lesion at the dose of 165 and 215 mg/kg, p.o., respectively. These results may indicate that remarkably.effective are ethyl acetate and butanol fractions in HCI-ethanol induced gastric lesion. Howeever, the fractions didn't exhibit any inhibition of gastric secretion and acid output. The buthanol fraction reduced significantly the acetic acid induced ulcer at a daily dose of 215 mg/Kg, p.o., given for 10 days. These result showed considerable inhibit of acetic acid induced ulcer without inhibition of indomethacin induced gastric lesion. The methanol extract showed low acute toxicity with minimum lethal dose of more than 3000 mg/kg, p.o. in mice. In conclusion, Eugenia F10s exhibited antigastric activity which might be attributable to inhibition of gastric secretion. It is indicated that activie component may be present in the buthanol fraction.
