This study was carried out to observe the antioxidative activity, fibrinolytic activity, nitrite savenging ability and adenosine content of three medicinal mushrooms. Among water and ethanol extract of each mushroom, water extract of Inonotus obliquus (Czech) showed the highest antioxidative activity $(57.1{\mu}g/ml)$, nitrite scavenging ability (52.04%), fibrinolytic activity (86.8%) and adenosin content $(94.3{\mu}g/g)$, whereas nitrite scavenging ability of ethanol extract of Phellinus linteus showed higher than that of water extract. Apart from the above statements, water was effective than ethanol as extracting solvent in general. These results suggest that Inonotus obliquus (Czech) showed higher activities such as antioxidative activity, nitrite scavenging ability, fibrinolytic activity and adenosin content and water was effective as solvent except for nitrite scavenging ability.

Pleurotus species are commercially essential mushrooms and widely cultivated throughout the world. The production of Pleurotus mushrooms alone accounts for around 25% of that total cultivated mushrooms globally. In America and Europe, Pleurotus species are considered specialty mushrooms, whereas, in Korea, their cultivation is economically profitable, and it is one of the highly consumed species. Pleurotus species are predominantly found in tropical forests and often grow on fallen branches, dead and decaying tree stumps, and wet logs. Biographical studies have shown that the Pleurotus genus is among the more conspicuous fungi that induce wood decay in terrestrial ecosystems worldwide due to its formidable lignin-modifying enzymes, including laccase and versatile peroxidases. Pleurotus species can be grown easily due to their fast colonization nature on diversified agro-substrates and their biological efficiency 100%. Pleurotus mushrooms are rich in proteins, dietary fiber, essential amino acids, carbohydrates, water-soluble vitamins, and minerals. These mushrooms are abundant in functional bioactive molecules, though to influence health. Pleurotus mushrooms are finding unique applications as flavoring, aroma, and excellent preservation quality. Apart from its unique applications, Pleurotus mushrooms have a unique status delicacy with high nutritional and medicinal values. The present review provides an insight into the cultivation of Pleurotus spp. using different agro-waste as growth substances paying attention to their effects on the growth and chemical composition.

한국과 중국에서 재배한 약용버섯인 노루궁뎅이, 동충하초, 영지의 열수추출물과 70% ethanol 추출물에 대해서 DPPH 라디컬 소거능, 아질산 소거능, 총 폴리페놀 함량, 베타글루칸 함량을 비교하기 위하여 측정하였다. DPPH 라디컬 소거능은 열수추출물과 70% ethanol추출물에서 한국산 노루궁뎅이와 동충하초가 월등히 높았으며, 추출용매별로 비교하였을 경우, 노루궁뎅이와 동충하초는 열수추출물의 항산화효능이 높았다. 아질산염 소거능의 경우, 한국산과 중국산 영지의 열수추출물에서 각각 41%와 39%로 나타나 70% ethanol 추출물에 비하여 높았다. 총 폴리페놀 함량은 한국산 노루궁뎅이와 동충하초는 열수추출물에서 높은 함량을 보였으며, 영지의 경우는 70% ethanol 추출물에서 더 높은 함량치를 나타냈다. 베타글루칸 함량은 한국산 동충하초가 45.11%를 보이며 가장 높았으며, 영지 역시 중국에서 재배한 것에 비하여 높은 함량을 나타냈다. 노루궁뎅이는 중국산이 한국산에 비하여 높은 베타글루칸 함량을 보였다. 위와 같은 결과로부터 각각의 버섯류에 맞는 최적의 용매를 사용해야 최대의 유효성분을 추출할 수 있다고 사료된다. 본 연구에서 사용한 노루궁뎅이, 동충하초, 영지가 한국 및 중국에서 재배되는 버섯의 대표성을 나타내기에는 부족하나 이러한 연구결과를 토대로 더 많은 비교샘플을 확보하여 약용버섯류에 대한 기능성 평가를 위한 기초자료로 활용하고자 한다.

The importance of utilizing biological resources has become magnified and it has been a big issue to share the benefit among nations as Nagoya Protocol began in 2010. This study was conducted to research the diversity and distribution of wild mushrooms, and to survey the traditional mushroom knowledge of the people in Jejudo which is a volcanic island having a distinctive climate and forest environment. The research sites were Dongbaekdongsan, Keuneonggot, Hallasan National Park, Muryeongarioreum, Saryeonisupgil and other important area where mushrooms are growing spontainously in Jejudo. A total of 511 species comprising 2 phylums, 8 classes, 20 orders and 74 genera were identified from 1600 specimens collected from 2006 to 2012. In previous studies, a total of 561 species comprising 69 families and 99 genera were investigated. As a result, a total of 755 species comprising 23 orders, 87 families and 263 genera were documented in Jejudo. In this study, 137 species were newly identified as unrecorded species in Jejudo and 9 species, Amanita gemmata, Tricholoma aurantiipes, Panellus violaceofulvus, Leucopaxillus septentrionalis, Bondarzewia montana, Psilocybe argentipes, Boedijnopeziza insititia, Sarcoscypha occidentalis for. occidentalis and Morchella patula var. semilibera were the first record for Korea. Also, 7 species, Amanita gemmata, Tricoloma aurantiipes, Panellus violaceofulvus, Leucopaxillus septentrionalis, Boedijnopeziza insititia, Sarcoscypha occidentalis for. occidentalis and Morchella patula var. semilibera were known as only growing in Jejudo. The traditional knowledge was collected from visiting and questionnaire survey in 50 villages in Jejudo. A total of 23 mushrooms were found in which 12 species were used for food, 2 species were poisonous, 6 species were medicinal, 2 species were used for folk religion and 3 species were used for play purposes. Macrolepiota procera was the most commonly used as an edible mushroom and Chlorophyllum neomastoidea was the most well known poisonous mushroom. Also, 267 cases of traditional knowledge about using mushrooms as a food and medicine were collected. This study has significance for supplementing previous studies about distribution of wild mushrooms in Jejudo and documenting unrecorded species in Korea.

A compressive description of tropical milky white mushroom (Calocybe indica P&C var. APK2) is provided in this review. This mushroom variety was first identified in the eastern Indian state of West Bengal and can be cultivated on a wide variety of substrates, at a high temperature range ($30{\sim}38^{\circ}C$). However, no commercial cultivation was made until 1998. Krishnamoorthy 1997 rediscovered the fungus from Tamil Nadu, India and standardized the commercial production techniques for the first time in the world. This edible mushroom has a long shelf life (5~7 days) compared to other commercially available counterparts. A comprehensive and critical review on physiological and nutritional requirements viz., pH, temperature, carbon to nitrogen ratio, best carbon source, best nitrogen source, growth period, growth promoters for mycelia biomass production; substrate preparation; spawn inoculation; different supplementation and casing requirements to increase the yield of mushrooms has been outlined. Innovative and inexpensive methods developed to commercially cultivate milky white mushrooms on different lignocellulosic biomass is also described in this review. The composition profiles of milky white mushroom, its mineral contents and non-enzymatic antioxidants are provided in comparison with button mushroom (Agaricus bisporus) and oyster mushroom (Pleurotus ostreatus). Antioxidant assay results using methanol extract of milky white mushroom has been provided along with the information about the compounds that are responsible for flavor profile both in fresh and dry mushrooms. Milky white mushroom extracts are known to have anti-hyperglycemic effect and anti-lipid peroxidation effect. The advantage of growing at elevated temperature creates newer avenues to explore milky white mushroom cultivation economically around the world, especially, in humid tropical and sub-tropical zones. Because of its incomparable productivity and shelf life to any other cultivated mushrooms in the world, milky white mushroom could play an important role in satisfying the growing market demands for edible mushrooms in the near future.
