  • To investigate on the element content of twelve edible mushrooms and Aloe arborescent, i.e., Lentinus edodes, Ganoderma lucidum (culturing in wood and soil), Tricholoma matsutake, Agaricus auricula-Jude (produced in Korea and China), sarcodon asparatus, Pleurotus ostreatus, Coriolus bisporus, Cyrophora esculenta, Auricularia auricula-Jude (produced in Korea and China), Sarcodon asparatus, Pleurotus ostreatus, Coriolus rersicolor, Smilax rotundifolia and Aloe arborescenstyl were analyzed by Atomic absorption spectrometer. The obtained results were summarized as follows : 1. Potassium, sodium, magnesium and iron content for the most part samples were in large quantities, especi phosphorus content of those was highest ammount for the all samples. 2. Sodium content f·as much ammount in the Lentinus edodes(39 mg, and Ganoderma lucidum(20 mg) , Culturing in wood and soil, while potassium was very high ammount in the Aloe arborescens and other samples. Mush ammount of magnesium as compared with others was Lentinus edodes(144 mg) , Ganoderma lucidum(128 mg), Aloe arborescens(50 mg) and Pleurotus ostreatus (60 mg) . 3, Phosphorus content of Lentinus edodes, Gyrophora esculenta, Auricularia polytricha and Agaricus bisporus was much ammount while iron content of all samples equality higher ammount. Sodium content of Aloe arborescens was not analyzed out for almost all, its potassium(82 mg), magnesium(50 mg) and iron(18 mg) content comparatively higher quentity than others nllnerals and phosphorus volume (4.9 mg) as compared with others, was conspicuously lower detect. 4. Cadimium and lead content of harmful metal element were detected on trace quantity for the most part samples. 5. Organic acids of samples i.e., Lentinus edodes, Agaricus bisporus, Pleuritus ostreatus and Ganoderma lucidum were Citrate, Malate, Fumalate, Succinate, Oxalate, Acetate, Lactate, and Tartarate and Citrate, Malate and Fumarate contents were higher amount remarkbly than other organic acids. Tartarate content was trace amount.

  • Lentinus edodes is a well-known edible and medicinal mushroom used in Oriental cultures. Recently, L. edodes has attracted a lot of attention owing to its antifungal activity, antibacterial activity, antiviral activity, hepatoprotective effect, antitumor activities, and immunomodulatory and cytotoxic effects. In this study, the water-soluble crude polysaccharides, CPF and CPB, which were obtained from the fruiting body and culture cell-free broth of L. edodes by hot-water extraction and ethanol precipitation, were fractionated by DEAE cellulose and Sepharose CL-6B column chromatography, resulting in six polysaccharide fractions, CPFN-G-I, CPFN-G-II, CPFN-G-III, CPFA-G, CPBN-G, and CPBA-G Among these fractions, CPFN-G-I, CPBN-G, and CPBA-G were shown to stimulate the functional activation of macrophages including NO production, cytokine expression, and phagocytosis.

  • 연구는 버섯을 이용한 기능성식품 개발 및 버섯가공 산업 육성에 기초자료를 제공하고자 표고버섯 및 느타리버섯 자실체, 균사체 및 폐상의 조단백다당체 분말을 0, 5, 25 mg/kg 농도로 생리식염수에 용해시켜 마우스(DBA/2와 ICR)에 주사하여 i) 백혈병$(L_{1210})$, 간암$(H_{22}),\;mouser{\;}sarcoma180\;(S_{180})$에 대한 항암효과, ii) 면역기전에 관련된 장기중량변화, 용혈반 형성 세포수 변화 등 조단백다당이 면역에 미치는 영향, 그리고 in vitro 세포독성실험을 수행하였다. 본 실험에서 사용한 모든 조단백다당류는 백혈병에 대해 항암효과를 보였는데 그 중 표고버섯자실체 25 mg/kg 처리구가 가장 높은 저지율(86%)을 보였다. 간암$(H_{22})$에 대한 항암효과는 표고버섯균사체 5 mg/kg 처리구를 제외하고 모든 처리구에서 저지효과를 보였는데, 그 중 느타리버섯 폐상 25 mg/kg 처리구가 가장 높은 저지율(87.6%)을 보였으며, 다음은 표고버섯자실체 25 mg/kg 처리구(71%)였다. Sarcoma180에 대한 항암효과는 표고버섯균사체와 자실체 25 mg/kg 처리구에서 각각 30.9,와 33.9%의 저지율을 보였다. In vitro 세포독성검사에서 각 시료의 최종농도 $50,\;100,\;200,\;400\;{\mu}g/{\mu}L$에서 $L_{1210}$에 대한 유의적 세포사망률은 보이지 않았다. 면역효과 실험에서 간장과 비장중량은 농도증가에 따라 증가하는 추세이나 현저한 차이는 없었다. 표고버섯균사체와 자실체 처리시 항체생성능력을 지닌 용혈반 형성 세포수는 대조군에 비해 현저히 높게 나타났다.

  • As the growth factor of lactic acid bacteria, LD (trehalose) was isolated from Lentinus edode5 by using silica gel column chromatography. LD induced the growth of Bifidobacteria breve and Lactobacillus brevis, which were isolated from human feces. LD selectively induced the growth of lactic acid bacteria among total microflora. When total intestinal microflora were cultured in the medium containing LD, it stimulated the growth of lactic acid bacteria and inhibited harmful enzymes, ${\beta}$-glucosidase, ${\beta}$-glucuronidase, and tryptophanase, of intestinal bacteria. LM, which was a monosaccharide from L. edooles, induced the growth of lactic acid bacteria but it seems to be invaluable in vivo. LH isolated from L. edodes by Sephadex G-100 column chromatography was not effective for the growth of lactic acid bacteria.

  • The possibility of solid-substrate fermentation of Lentinus edoes for the productin of protein-boud polysaccharides (PBP) was studied. Zeolite and orchid-pot soil were used as solid materials for the culture because of the desirable physical properties. Sucrose and starch were good carbon sources for the production of PBP by the solid-substrate fermentatin of L. edodes. Among the nitrogen source, bactosoyton was very effective for the PBP production. The optimum pH for solid-substrate fementation for the production of PBP was at pH of 5.5. The PBP production reached to 5∼5.5mg per 100g solid-substrate.

  • Many studies have showen that Letinus edodes have a reducing effects on blood pressure and lipid levels in animals with high blood pressure and hyperlipidemia. But the only cap has been on the market as goods and the stipe has been wasted. The price is very variable and is based on harvest time and the part of the plant currenty, there is not much information about the nutritional composition and bio-fuctional effects of Letinus edodes based on harvest time and part. Some farmers have been selling the powder seasoning by drying and pulverizing Letinus edodes including stipe to develop value added, late harvested Letinus edodes and its stipe these days. This study was conducted to investigate and compare the nutritional composition of Letinus edodes harvested at different times (early: E, late: L) and separated by part (cap: C, stipe: S). The 4 kinds of materials were named as early harvested cap (EC) and stipe (ES), and late harvested cap (LC) and stipe (LS) samples were obtained from Mungyeong City Agricultural Technology & Extension Center. The composition analysis of the nutrients in the 4 materials was conducted by using the AOAC method. The proximate components (moisture, protein, fat, fiber, ash, and carbohydrates), minerals and vitamin content were measured. Nutritional composition of Lentinus edodes did not show any significant difference between early and late harvested mushrooms. Nutritional compositions were different according to part. The results demonstrate that the late harvested stipe can also be used as a quality food material.
