  • The purpose of this study was to investigate extract from mixed culture with Trichloloma matsutake mycelium in oriental medicine and cereal medium(OCM) to develop new material for pharmaceutical products and medicinal food for diabetes mellitus. To evaluate of hypoglycemic activity of OCM extracts, we examined the inhibitory activity of ${\alpha}$-glucosidasein OCM, blood glucose level and liver function of streptozotocin(STZ) induced diabetic rat. Experimental group was divided into 6 groups: first, it was divided into normal control group(hereafter NC group) and diabetes-induced group, and diabetes-induced group was subdivided into diabetic control group(DC group), treated by hot water extracts group(HE), ultra sonic waves, micro waves, and micro bubble extracts g roup(UE), crude polysaccharide of HE group (HEE) and crude polysaccharide of UE group(UEE) at a dose of 300mg/kg/body weight, respectively. In diabetic-induced groups, after streptozotocin was melted in 0.01M citrate buffer at 50mg/kg/body weight, when the non-fasting blood glucose levelwas 300 mg/dl or more in blood collected from the tail vein, it was regarded as diabetic induction and then such diabetic-induced experimental animals were used in this experiment. At the end of the experiment, blood glucose level increased by 4.19% in DC group but significantly decreased by 32.34%, 19.19%, 17.81% and 17.64%, respectively in UEEE, UE, HE, and HEE groups. In the cases of AST, ALT, and ALP, the experiment group treated with extracts showed significantly lowerblood glucose level than DC group. The levels of BUN and uric acid were found to be lower in the UMPM extract group(UE) than HW extract group(HE), which implies that herb medicine medium extracts in which Tricholoma matsutake mycelia were cultured are effective in reducing impaired liver function as well as high blood glucose level caused by diabetes. In addition, the administration of low temperature UMPM extracts was found to produce better results than that of high temperature hot water extracts. In this regard, it is expected that extracts from herb medicine obtained by cultivating Tricholoma matsutake mycelia will be widely used as new ingredients for foods and medicines for prevention and treatment of diabetes.

  • The crude polysaccharides(C-CPF, C-CPM, C-CPB) derived from fruiting body, mycelia and mycelia free broth of cordyceps militaris were obtained by ethanol precipitation of hot water extracts. After a batch fermentation of C. militaris was carried out in a 5 L jar vessel, endo-polysaccharide and exo-polysaccharide were obtained. They were demonstrated as the hetero polysaccharides which were composed of glucsose, galactose and mannose by performed with HPAEC(high pH anion exchange chromatography) and conformation of random coil by its complex forming ability with congo red reagent. They were purified by ion exchange (DEAE-cellulose) and gel filtration chromatography. They were monitered by phenol-sulfuric acid method and Bradford method. The NO induction activities of crude polysaccharides and purified polysaccharides derived from mycelia free broth were enhanced rather than LPS(lipo polysaccharide) which was used as a general NO inducer. These effects presumably contibute to the antitumor activities. The homogenieties and molecular weights of polysaccharides were determined by using Sepharose CL-6B. The yield, molecular weights and NO induction activities of C-CPFN Fr.III, C-CPMN Fr.III, C-CPBN Fr.II were 0.387, 0.408 and 0.153, 127 K 210 K and 36 K, 40.79%, 88.72%, and 104.17%, respectively.

  • 식용버섯으로부터 항보체 활성물질을 탐색하여 새로운 소재화 연구의 일환으로 상황버섯(Phellinus linteus) 균사체로부터 항보체 활성 물질을 분리, 정제를 하였으며 화학적 특성을 검토하였다. 정제는 상황버섯의 열수추출한 후, 열수추출물(PL-0)를 한외여과하여 분자량별로 5개의 획분을 얻었다. 이 중, 300kDa 이상의 획분(PL-5)을 DEAE-Sepharose FF 이온교환 크로마토그래피, Sepharose CL-4B 겔여과 크로마토그래피를 실시하여 PL-5-IIIa 획분을 얻었다. PL-5-IIIa 획분을 HPLC를 행한 결과 단일 피크로 나타났으며 정제다당 PL-5-IIIa의 분자량은 800,000Da으로 측정되었다. 정제다당 PL-5IIIa는 64.2%의 당과 29.6%의 단백질로 구성되었으며 구성당은 galactose가 43.1%, mannose가 40.6%, fucose가 15.8%로 나타났다.

  • 본 연구는 민들레잎을 노루궁뎅이버섯 균사체로 발효한 후물과 에탄올로 추출하여 추출용매별 및 발효 전과 발효 후의 항산화 및 항염증 활성을 비교 평가하였다. 추출물의 항산화 활성을 탐색하고자 총 폴리페놀 함량, 총 플라보노이드 함량, DPPH 라디칼 소거능, ABTS를 이용한 라디칼 소거 활성, FRAP을 이용한 총 항산화능을 측정하였다. 또한 RAW 264.7 대식세포를 이용하여 NO 생성량, 염증관련 단백질 및 사이토카인의 변화를 측정하였다. 민들레잎을 발효한 후 항산화 활성은 감소하였으나 오히려 항염증 활성은 증가하는 경향을 나타내었다. 특히 발효 민들레잎의 에탄올 추출물은 NO 생성 및 iNOS 단백질 발현을 효과적으로 억제하였으며 염증성 사이토카인인 IL-6를 억제하는 효과가 우수하였다. 이상의 결과로 항염증 소재로서 노루궁뎅이버섯 균사체를 이용한 발효 민들레잎의 에탄올 추출물의 활용 가능성을 확인하였다.

  • 각종 버섯에서 항보체 활성균주를 선별하기 위해 보관균주 50여종과 임업협동조합에서 분양 받은 20여종의 균주를 대상으로 항보체 활성을 검색한 결과, 항보체 활성이 65.3%를 나타낸 상황버섯 (Phellinus linteus)을 선별하였다. 본 균주가 생산하는 항보체 활성의 본체를 파악하기 위해 pronase 처리와 periodate 산화를 행한 결과 pronase로 처리한 사료는 무처리군과 비교하여 차이가 없었던 반면 periodate로 산화시킨 시료는 항보체 활성이 크게 감소함에 따라 P. linteus가 생산하는 항보체 활성의 본체는 다당에 기인되는 것으로 추정되었다. 항보체 생산을 위한 최적 배양조건은 soluble starch 3.0%, peptone 0.3%, yeast extract 0.4%, $MgSO_4{\cdot}7H_2O$ 0.1%, $K_2HPO_4$ 0.2%, 초기 pH 7.0, 배양 온도 $30^{\circ}C$ 및 교반속도 150rpm이었다. 상기의 최적 배양조건에서 jar fermentor로 18일 배양하였을 때 88%의 항보체 활성과 15mg/mL의 균사체 생육을 나타내었다.

  • Methyl trans-cinnamate is a significant flavor compound of Tricholoma matsutake. Attempts were made to produce this compound by culturing the mycelium using submerged culture. No methyl trans-cinnamate could be detected when the mycelium was cultured in the basal liquid medium. However, the addition of Pinus desiflora extracts to the medium, methyl trans-cinnamate was largely produced. To find out compounds or fractions inducing methyl trans-cinnamate, dichloromethane fraction obtained from the wood extracts of P. densiflora was subjected to column chromatography. Three sub-fractions were obtained from the $CH_2CI_2$ fraction. Submerged cultured mycelium treated with sub-fraction 1 has the highest content of methyl trans-cinnamate. Maximum methyl trans-cinnamate $(470.2{\mu}g/g)$ was obtained when the first sub-fraction of dichloromethane fraction of the P. densiflora wood extracts was added to the medium. This indicates that wood extracts of P. densiflora contains inducer of the methyl trans-cinnamate production in the T. matsutake submerged culture.

  • It has been known that the novel diterphenoids, hericenone and erinacine isolated from the fruiting body and cultured mycelia of Hericium erinaceus showed potent stimulating activity of nerve growth factor (NGF)-synthesis. To investigate the biological activities of extracts from fruiting body, cultured mycelium and cell-free broth of H. erinaceus, the activity experiments of antioxidation and AChE inhibition were carried out. Sephadex G-10 gel filtration followed by HPLC on a ${\mu}Bondapak$ $C_{18}$ column of EtOAc extract from cultured mycelium showed a biological activity.
