  • The hypolipidemic effects of soybeam paste containing mycelia of Phellinus linteus, Cordyceps militaris, Ganoderma lucidum were evaluated in hyperlipidemic rats. Body weight of the rats fed with soybean paste containing mycelia of Ganoderma lucidum (ESG) were significantly lower than control group whereas, there was no significant difference in body weight in order diet groups. Food intake, food efficiency ratio, and liver and kidney weights were not significantly different among the diet groups examined. However, the spleen weight of ESG group was markedly lower than other groups. Significant decreases in serum total cholesterol, LDL-cholesterol and liver total cholesterol were also observed in all diet groups tested. All groups fed with soybean paste containing mycelia of mushroom were also observed in all diet groups tested. All groups fed with soybean paste containing mycelia of mushroom were almost equally effective in increasing plasma HDL level and decreasing the atherogenic index, whereas the ratio of HDL to total cholesterol was significantly increased in all experimental diet groups.

  • The purpose of this study was to investigate antioxidative and nitrite scavenging activities of extracts of Cordyceps militaris. Fruiting body and mycelia of artificially cultivated Cordyceps militaris were extracted with water and 70% ethanol. In Cordyceps militaris mycelia, electron donating ability (EDA) of water extract ranged from 37% to 47% and ethanol extract ranged from 57% to 70% at 300∼1,000 ppm. In Cordyceps militaris fruiting body, EDA of water extract and ethanol extract were similar, ranged from 19% to 48% at 300-1,000 ppm. Nitrite scavenging ability (NSA) of extracts measured at various pH (1.2, 3.0, 4.2, 6.0) was the highest at pH 1.2 and decreased with increasing pH, suggesting it is pH dependent. In Cordyceps militaris mycelia, NSA of water extract 1,000 ppm was 23% and that of ethanol extract 1,000 ppm was 37% at pH 17. In Cordyceps militaris fruiting body, NSA of water extract 1,000 ppd was 12% and that of ethanol extract 1,000 ppm was 37% at pH 1.2. EDA and NSA of Cordyceps milituis were higher in extract of mycelia than fruiting beds and higher in ethanol extract than water extract of each part.

  • Phellinus linteus mycelia have many pharmacological effects, although their pharmacological efficacy principles have not been known yet. In the course of screening for biological activity of the extracts of Phellinus linteus mycelia, we found strong antioxidative activity in some fraction of water-insoluble. Therefore, we tried to isolate the active principle(s) from the extract. The isolation of the active compound was guided by superoxide anion radical scavenging activity. As a result, caffeic acid was isolated as an active compound. The IC$\_$50/ of the compound was 3.05 $\mu$g/ml (16.9$\mu$M).

  • In this study, the optimum conditions for mycelium culture of the mushroom Tricholoma matsutake and the inhibitory effect of the mycelium extracts no tyrosinase activity have been examined. When the extracts of the Tricholoma matsutake mycelia were tested for inhibitory activity on tyrosinase, it was found that the components extracted with ethyl acetate and water showed the highest inhibitory activity. The effect of antioxidants on the growth of mycelium and tyrosinase-inhibiting activity was also investigated. The results showed that tocopherol inhibited the growth in a concentration-dependent manner. In terms of tyrosinase-inhibiting activity, however, tocopherol was found to enhance the inhibitory activity.

  • To enhance the physiological activity of the Rhynchosia volubilis (RV), R. volubilis (RVHE-A) and R. volubilis-added herbal powder (RVHE-B) were fermented with a solid state culture of Hericium erinaceum mycelia (HE). The total isoflavone contents of the non-fermented RV-A ($489.9{\mu}g/g$) and RV-B ($571.1{\mu}g/g$) were remarkably increased in fermented RVHE-A ($1,836.4{\mu}g/g$) and RVHE-B ($1,276.7{\mu}g/g$). In particular, aglycone isoflavones such as daidzein and genistein were significantly higher in the RVHE-A than any other sample. When hot-water (HW) and EtOH extracts (E) were fractionated from the RV and RVHE, both extracts from the RVHE-A were higher than those from the RV-A in total polyphenol and flavonoid contents. However, the RVHE-B-HW showed a lower polyphenol and flavonoid content level than did RV-B-HW. RVHE-A-HW and -E also had more potent ABTS radical scavenging activity than any extract from the non-fermented RV and other ferments (RVHE-B). In the meanwhile, RVHE-A-HW potently stimulated the production of macrophage activation-related cytokines such as $TNF-{\alpha}$, IL-6 and IL-12 ($841.7{\pm}71.3pg/mL$, $3.9{\pm}0.1ng/mL$, $179.3{\pm}30.2pg/mL$) from peritoneal macrophage more than RV-A-HW ($92.5{\pm}1.5pg/mL$, $0.1{\pm}0.0ng/mL$, $37.4{\pm}5.4pg/mL$) as well as RVHE-B-HW ($557.0{\pm}21.3pg/mL$, $1.8{\pm}0.0ng/mL$, $90.0{\pm}10.0pg/mL$). However, all the EtOH extracts did not show significant activity. In addition, the RVHE-A-HW showed a significantly higher intestinal immune system modulating activity through Peyer's patch and GM-CSF production than did any other extract from RV and RVHE-B. In conclusion, these results suggest that the fermented R. volubilis with H. erinaceum mycelia possesses a possible use as an industrial application as functional food or material.

  • 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.

  • Incubation condition affecting the chlamydospore formation and isolation from mycelia and conidia of Cylindrocarpon destructanse (isolate ACY-9701), isolated from the root rot lesion of the American ginseng (Panax quinquefolium) was investigated. Chlamydospores were formed from mycilia but not from conidia on the Czapek-Dox agar without carbon or nitrogen source after 20 days incubation at 2$0^{\circ}C$. In the medium added with nitrogen and carbon sources, immatured chlamy-dospore-like cells were formed from microconidia and mycelia as well. Immatured chlamydospore-like cells were formed from mycelia as well as microconidia In corn, kidney bean, and pea root extracts after 20 days incubation at 20"C, while typical chlamydospores were formed from both of them in the root extract of Panax quinquefolium. The 3.6 log chlamydospore/mm" was converted from microconidia in the medium, which was equal to 2.5% conidia formed. Under the light condition (251.1 pmol/m" sec, 12 hrs dark and light cycle), 4.2 log/mm" of chlamydospores were converted from interracially or terminal cells of macroconidia, which was 4.0% of macroconidia produced on Potato dextrose agar (PDA). When mycelia and microconidia were stored at -7$0^{\circ}C$ for 32 days and incubated on PDA after thawing at room temperature to isolate chlamydospores from them, microconidia and mycelia were still alive. Meanwhile, microconidial lysis was found after heating them at 32$^{\circ}C$ for 7 days, but the chlamydospores converted from macroconidia were not lysed up to 13 days at 32"C. to 13 days at 32"C.ot;C.
