The current study was performed to determine the acute oral toxicity of a crude extract of sanghwang mushroom (Phellinus linteus), in SD rats. 5 rats of each sex were orally treated with a single dose of extract of sanghwang mushroom at doses of 0, 500, 1,000, 2,000 mg/kg, respectively. After the treatment, clinical signs and body weight change, the food and water consumption were observed for 14 days. All animals survived during the study and did not show any clinical signs. Body weight gain showed no significant difference between the control and treated rats. However, body weight gain delayed in high dose group (2,000 mg/kg) on day 1~3 after administration. Another 5 rats of each sex were orally treated with a single dose of extract of sanghwang mushroom at dosages 4,000, 5,000 mg/kg respectively, but all animals survived during the study and did not show any clinical signs. It is suggested that LD$_{50}$ of extract of sanghwang mushroom by oral administration was estimated to be over 5,000 mg/kg in both sexes of rats.s.

P. linteus(품종명: 고려상황, PLKS)와 P. baumii (장수상황, PBJS)를 동일한 조건하에서 인공재배하여 얻어진 자실체를 70% 메탄올, 60% 에탄올, 열수추출하여 폴리페놀과 플라보노이드 측정 시 함량은 60%에탄올 추출물에서 가장 높게 나타났다. 60%에탄올을 용매로 PLKS와 PBJS의 자실체를 추출하여 농도별로 DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2'-azino-bis (3-ethylbisthiazoline-6-sulfonic acid) 라디칼 소거능을 측정한 결과 PLKS와 PBJS는 거의 유사한 항산화 활성을 보였으며 자실체가 균사체보다 2-3배 이상 높은 항산화 활성이 측정되었으나 FRAP (ferric reducing antioxidant power)분석에서는 자실체와 균사체 간에 큰 차이가 없는 것을 확인하였다. PLKS와 PBJS의 자실체 ethyl acetate 분획물을 HPLC 분석한 결과 styrylpyrone 계 폴리페놀 성분인 davallialactone, hispidin, hypholomine B, inoscavin A를 검출할 수 있었으나 균사체에서는 검출되지 않아 자실체 특이적인 화합물인 것을 확인하였다.

The principal objective of this study was to examine the quality characteristics of yanggaeng supplemented with powder derived from Sanghwang mushroom (Phellinus linteus) mycelia. We analyzed the potential of utilizing Phellinus linteus mycelia as a functional food material by estimating total polyphenol and flavonoid contents, electron-donating abilities, as well as antioxidative activities of the water and ethanol extracts of Sanghwang mushroom mycelia. The total phenol and flavonoid contents of ethanol extracts from Phellinus linteus mycelia were 0.69 mg/ml and 0.16 mg/ml, respectively, while the contents from the water extract of Phellinus linteus mycelia were 0.66 mg/ml and 0.22 mg/ml, respectively. The electron-donating abilities of ethanol and water extracts from Phellinus linteus mycelia were 88.64 and 90.29%, respectively. The ABTS radical scavenging activities of ethanol and water extracts from Phellinus linteus mycelia were 89.74 and 71.35%, respectively. In terms of color values, as the level of powder increased, the value of L (lightness) decreased, whereas those of a (redness) and b (yellowness) increased. In regard to the mechanical properties of the samples, we noted significant differences in hardness, springiness, chewiness, and gumminess (P<0.05). The results of the sensory evaluation showed that the score from SHM (Sanghwang mushroom mycelia) with 4% powder was significantly higher than other samples in terms of sweetness, color, taste, texture and overall quality (P<0.05). Taken together, the recommended level of Phellinus linteus mycelia powder in yanggaeng is 4% for optimal sensory characteristics.

The present study was performed to evaluate the hangover relieving effect of germinated buckwheat (GB) and Sanghwang mushroom mycelium cultured in GB (SGB). Both GB and SGB showed 1,1-diphenyl-2-picrylhydrazyl radical scavenging activities and significantly increased (p < 0.001) aldehyde dehydrogenase (ALDH) activities; up to 140% increase at concentrations of $16{\mu}L/mL$. Locomotor activity test results from alcohol-SGB and alcohol-GB groups showed improved motor activities over that of the alcohol-water group at 90 min post-administration. Both alcohol-GB and alcohol-SGB groups had significantly reduced (p < 0.001) alcohol ($40.02{\pm}33.38{\mu}g/mL$, $66.01{\pm}22.04{\mu}g/mL$, respectively) and aldehyde ($5.72{\pm}0.47{\mu}g/mL$, $6.72{\pm}1.70{\mu}g/mL$, respectively) concentrations in blood compared to those in the alcohol-water group ($199.75{\pm}33.83{\mu}g/mL$, $50.43{\pm}13.88{\mu}g/mL$, respectively) at 90 min post-administration. Based on cDNA microarray analysis, expressions of ALDH genes ALDH1a7 and ALDH18a1 and cytochrome P450 (CY450) gene CYP4a30b were upregulated in the alcohol-GB and alcohol-SGB groups compared to levels in the control group. Overall, the results suggest that both GB and SGB have hangover relieving effects by reducing blood acetaldehyde levels. The molecular mechanisms may involve ALDH activation and upregulated expression of alcohol metabolism-related genes such as ALDH and CYP450.

This study was conducted to evaluate the hangover relieving effect of Sanghwang mushroom mycelium extract (SME). The extract showed 1,1-diphenyl-2-picrylhydrazyl radical scavenging effect in a concentration-dependent manner and high antioxidant capacity ($56.67{\pm}1.77%$) when administered at $120{\mu}g/mL$. In addition, SME significantly increased (p < 0.005) the aldehyde dehydronase (ALDH) activity ($126.03{\pm}9.11%$) when applied at 8 or $16{\mu}L/mL$. A locomotor activity test showed that the alcohol-water treated group showed significantly decreased motor activity at 90 min post-administration. However, the alcohol-SME treated group showed a 20-fold higher motor activity than that observed in the alcohol-water treated group at 90 min post-administration. Blood was harvested from each mouse at 90 min post-administration, and both alcohol and aldehyde concentrations were measured. The alcohol-SME treated group showed significantly lower (p < 0.5) alcohol ($120.13{\pm}12.83{\mu}g/mL$) and aldehyde ($7.26{\pm}1.22{\mu}g/mL$) concentrations than the values observed in the alcohol-water treated group. These results suggest that the hangover relieving effect of SME results from increased ALDH activity, which reduces the aldehyde concentration in the blood.

The inhibitory activities of a water extract of Sanghwang mushroom(Phellinus linteusau)(SWE) against ${\alpha}$-glucosidases were evaluated in this study. Inhibiting these enzymes involved in the absorption of disaccharides significantly decreases the postprandial increase in blood glucose level after a mixed carbohydrate diet. Oxygen radical absorbance capacity and 1,1-diphenyl-2-picryl hydrazyl scavenging activities of the SWE were evaluated to investigate the antioxidant activity of the SWE associated with complications of long-term diabetes. Furthermore, the postprandial blood glucose lowering effect of SWE was compared to a known type 2 diabetes drug($Acarbose^{(R)}$) in a Sprague-Dawley rat model. SWE significantly reduced the blood glucose increase after sucrose loading. These results suggest that SWE, which has high ${\alpha}$-glucosidase inhibitory activity and high antioxidant activities, has the potential to contribute to a useful dietary strategy for controlling postprandial hyperglycemia.
