  • Objectives : The purpose of this study is to evaluate antioxidant activities and reducing serum alcohol concentration of extract of Lentinus edodes on the alcohol administered rats. Methods : Antioxidant effect was measured by total phenolic compound and DPPH-radical scavenging activity of extract of Lentinus edodes in vitro. Blood alcohol concentration, aldehyde concentration, malondialdehyde concentration, glutathion concentration were measured in vivo. Results : The extract of Lentinus edodes increased DPPH-radical scavenging activity dose-dependently. The water extract with boiling water showed lower antioxidant activity and phenolic content than 70% ethanol extract in vitro. Blood alcohol concentration was significantly reduced by pre-treatment of ethanol extract of Lentinus edodes. The effect was more significant than commercial product used as a positive control. Conclusions : This study suggest that Lentinus edodes can be a potential nature resource for the management of ethanol toxicity although the mechanism of action involved in the treatment remains to be explored.

  • Abnormal regulation of glucose and impaired lipid metabolism that result from a defective or deficient insulin are the key etiological factor in type 2 diabetes mellitus (T2DM). The our study evaluated the beneficial effect of diet supplementation with Lentinus edodes on hyperglycemia and lipid metabolism in normal and type 2 diabetic rats. The animals were divided into 4 groups: group I(control) rats were fed standard diet (12% of calories as fat); group II (T2DM) rats were fed HFD (40% of calories as fat) for 2 weeks and then injected with STZ (50 mg/kg); group III and group IV rats were continually fed a diet containing 1% and 10% Lentinus edodes for 4 weeks after T2DM induction, respectively. After 4 weeks we determined biochemical parameters such as glucose, insulin concentration, serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and glycosylated hemoglobin (HbA1c) concentration were also measured. There was a significant reduction in serum TC and TG in the Lentinus edodes supplement groups. The Lentinus edodes diet supplementation were found to have a potent lipid metabolism improvement as well as LDL concentration decreased and HDL concentration was increased. Concentrations of blood glucose and HbA1c in the experimental groups II were significantly decreased after 4 weeks compared with the control group. The Lentinus edodes diet supplementation is useful in regulating the glucose level, improves the insulin, HbA1c, serum lipid metabolism in experimental diabetic rats. We suggest that Lentinus edodes supplementation may have the control effects of diabetes mellitus by improving blood glucose control and lipid metabolism.

  • It has been known that Ganoderma lucidum and Lentinus edodes have anticancer activity and immune enhancing activity. These two mushrooms were grown in liquid culture and harvested. From these mycelia, DNA was isolated and EtBr-CsCl density gradient ultracentrifugation was performed to purify it further. Then mitochondrial DNA was isolated by bisbenzimide-CsCl density ultracentrifugaton. Mitochondrial DNA of Ganoderma lucidum was digested by restriction enzymes, EcoR I, Hind Ⅲ, and Pst I, then electrophoresed. It showed 12, 22, 4 fragments. Mitochondrial DNA of Lentinus edodes was digested by EcoR I. Electric pattern showed 6 fragments. 4 fragments had appeared by Pst 1 digested mitochondrial DNA. Hind ill couldn't digest mitochondrial DNA of Lentinus edodes. Mitochondrial DNA of fusants was isolated to compare to those of parents. The results showed that fusant P₂S₄has new, recombined mitochondrial DNA. But P₂S₄had the same DNA that Ganoderma lucidum had.

  • Elevated blood levels of homocysteine (a sulfur-containing amino acid) have been linked to increased risk of cerebrovascular disease including Alzheimer's disease. A recent study suggests that elevated homocysteine levels may lead to replicative senescence in vitro called 'permanent arrest of cell cycle' caused by oxidative stress. In this study, serum homocysteine level in rat was reduced by Lentinus edodes-powder diet, resulting in the reduced level of oxidative stress in rat brain. In addition, homocysteine-induced replicative senescence treated with or without Lentinus edodes-powder was analyzed by population doubling in vitro. The Lentinus edodes-powder induced a increased number of population doubling in primary neuron cell isolated from rat-cerebral cortex. This indicates that Lentinus edodes-powder would delay a homocysteine-induced aging of neuron cells in brain, showing a possible role in preventing cerebrovascular diseases including Alzheimer's disease.

  • 본 연구에서는 표고버섯 분말을 4%, 8%, 12%로 첨가하여 쌀 쿠키를 제조하고 품질 특성, 항산화 활성 및 기호도 조사를 실시하여 기능성 쿠키를 개발하고자 하였다. 쿠키반죽의 밀도는 표고버섯 분말 첨가량이 증가함에 따라 증가하였고 pH는 감소하였다. 쿠키의 수분 함량은 대조군이 8.32%로 가장 높았으며 첨가군은 4.73-5.56%로 대조군보다 낮았다. 표고버섯 분말 첨가량이 증가함에 따라 퍼짐성, 손실률, 팽창률 모두 감소하였다. 쿠키의 색도는 표고버섯 분말 첨가량이 증가함에 따라 L 값은 감소하였고 a 값은 증가하였으며 b 값은 대조군이 가장 높았다. 경도는 대조군이 가장 낮았고 12% 첨가군이 가장 높았다. 쿠키의 미세구조는 표고버섯 분말 첨가량이 증가할수록 표면과 내부 조직이 치밀해졌다. 총 폴리페놀 함량은 9.78-18.18 mg GAE/100 g의 범위로 표고버섯 분말 첨가량이 증가함에 따라 증가하였고, DPPH radical 소거능과 환원력도 증가하였다. 기호도 조사 결과, 색은 대조군이 높은 기호도를 나타내었으며 냄새, 맛, 전체적인 기호도는 대조군을 포함한 모든 시료들 간에 유의적인 차이가 없었다. 이러한 결과로 보아 쿠키에 표고버섯 분말을 첨가하는 것은 쿠키의 기호도를 증가시키고 동시에 항산화 활성을 증가시킴으로써 쿠키의 가치를 높여 줄 것으로 기대되며, 쿠키 제조 시 표고버섯 분말을 12% 첨가하는 것이 바람직할 것으로 사료된다.

  • 본 논문에서는 상품성이 없는 갈변된 표고버섯을 paste형태로 만들어 첨가량을 달리하여 생국수를 제조하고 조리 전과 후의 국수의 품질 특성을 살펴보았다. 표고버섯 paste 첨가에 따라 조리 후 국수의 무게, 부피 및 수분 보유력이 증가하였으며 ��은 국물의 탁도는 감소하여 조리 후에도 면발이 쉽게 풀어지지 않음을 알 수 있었다. 또한, 생국수와 조리국수 모두 표고버섯 paste 첨가량이 증가할수록 경도와 검성은 감소하고 탄력성은 증가하여 제면 특성이 좋아지는 것으로 나타났다. 관능검사 결과, 국수의 색상에 대한 기호도와 관계없이 향, 맛, 부드러운 정도, 씹힘성 및 전반적인 기호도가 표고버섯 paste 첨가에 의해 증가하였다. 따라서 밀가루에 표고버섯 paste를 첨가함으로써 국수의 품질과 기호성이 향상되는 것으로 보이며, 특히 20%와 30% 첨가 시 가장 좋은 품질 특성을 나타내었다.

  • To find the role of polyphenol oxidase in lignin biodegradation, chracteristics of extracellular polyphenol oxidase activity from Lentinus edodes JA01 was investigated. Polyphenol oxidase had its optimum activity at pH 4.5 and $45^{\circ}C$ respectively. Also, the enzyme was very unstable in various pHs and comparatively heat stable up to $60^{\circ}C$. In $lignosulfonate-NH_4$ salts medium, the growth rate of L.edodes JA 01 was relatively slow and polyphenol oxidase activity appeared 2 and 14 days after inoculation. No significant relationships were found between polyphenol oxidase activity and the amounts of lignosulfonate present in the culture medium.

  • Objectives: Lentinus edodes is an edible mushroom with a variety of beneficial effects such as antitumor, anti-inflammatory, antioxidant, and immune-modulatory activity. This study was carried out to evaluate the antimicrobial activities of Lentinus edodes extracts against oral-related bacteria. Methods: The antimicrobial activities of this extracts were investigated against S. anginosus, S. sobrinus, S. aureus, S. mutans, S. ratti, S. sanguinis, A. viscosus, A. naeslundii, and A. actinomycetemcomitans by the disc diffusion method, minimum inhibitory concentration (MIC), and growth inhibition. Results: Ethanol extracts had no antimicrobial activities, but acetone extracts showed antimicrobial activities against A. viscosus and A. actinomycetemcomitans and ethyl acetate extracts had effects against S. aureus, S. sanguinis, A. viscosus, and A. actinomycetemcomitans. Conclusions: The inhibitory effect of Lentinus edodes extracts was investigated on the growth of A. viscosus. Ethyl acetate and acetone extracts showed 90% and 77% inhibitory effect, respectively, against A. viscosus for 24 hrs. Ethyl acetate extracts had MIC of 25.0 mg/ml and acetone extracts showed MIC of >25.0 mg/ml.
