Abstract
For the searching of antibiotics in the mushroom, we studied on the screening of antiyeast and antifungal components. The powder of fruiting body of each mushroom was extracted with petroleum ether, 80% ethanol, and distilled water in that order, respectively. The antifungal activity of each extract from 32 different mushrooms were tested. The petroleum ether or ethanol extracts from fruiting bodies of Boletus auripes, Leccinum extremiorientale, Gomphus floccosus, Phaeolus schweinitzii, Pycnoporus cinnabarinus and Marasmius maximus showed antiyeast activities. The ethanol extract of Gyrophora esculenta showed an antiyeast activity against Cryptococcus neoformans, and its minimal inhibitory concentration (MIC) was $600\;{\mu}g/ml$. The petroleum ether or ethanol extracts from fruiting bodies of Amanita citrina, Leccinum extremiorientale, Gomphus floccosus, Phaeolus schweinitzii, Pycnoporus cinnabarinus, Marasmius maximus and Gyrophora esculenta showed antifungal activities. The ethanol extract of Gomphus floccoscus showed an antifungal activity against Microsporum gypseum, and its MIC was $1,000\;{\mu}g/ml$. The ethanol extract of Gyrophora esculenta showed antifungal activities against Trichophyton mentagrophytes, Microsporum gypseum and Pyricularia oryzae, and theirs MIC were $300\;{\mu}g/ml,\;600\;{\mu}g/ml\;and\;600\;{\mu}g/ml$, respectively. The petroleum ether extract of Gyrophrora esculenta also showed an antifungal activity against Microsporum gypseum, and its MIC was $300\;{\mu}g/ml$.
32종의 한국산 버섯을 석유에테르, 80% 에탄올 및 증류수로 각각 추출하여 항진균 활성을 검색한 결과, 수원그물버섯, 거친껄껄이그물버섯, 나팔버섯, 해면버섯, 주걱간버섯 및 석이버섯의 에탄올 추출물 그리고 큰낙엽버섯의 석유에테르 추출물이 효모에 대하여 활성을 보였다. 특히 석이버섯의 에탄올 추출물은 C. neoformans균에 큰 활성을 보였으며, 그 MIC 값은 $600\;{\mu}g/ml$ 이었다. 애광대버섯, 거친껄껄이그물버섯, 나팔버섯, 해면버섯, 주걱간버섯, 큰낙엽버섯 및 석이버섯의 에탄올 추출물과 석유에테르 추출물은 곰팡이에 대하여 각각 항균활성을 보였다. 또한 나팔버섯의 에탄올 추출물은 M. gypseum균에 대하여 $1,000\;{\mu}g/ml$ 이었고, 석이버섯의 에탄올 추출물은 T. mentagrophytes, M. gypseum 및 P. oryzae균에 대하여 각각 $300\;{\mu}g/ml,\;600\;{\mu}g/ml$ 및 $600\;{\mu}g/ml$ 였으며, 이 버섯의 석유에테르 추출물은 M. gypseum균에 대하여 $300\;{\mu}g/ml$의 MIC 값을 보였다.
