Sarcodon aspratus (Thelepholaceae), a native mushroom, is distributed in Korea and Japan, and has been widely used in traditional food and fork medicines. To confirm the biological activities of Sarcodon aspratus, the liver protecting activity, anti-clotting activity, and anti-complementary activity of the water extract, EtOH extract, and the water soluble proteoglycan part of S. aspratus were investigated. The EtOH, and water extract of S. aspratus decreased the GOT and GPT releases induced by $CCl_4$ in a dose-dependant manner. On the other hand, the water soluble proteoglycan part of S. aspratus showed weak inhibitory activity. In addition, the EtOH and water extract of S. aspratus prevented $CCl_4-induced$ hepatotoxicity, as described by a liver histopathologic study. To confirm the anti-clotting activity, the APTT and PT assay were carried out. As a result, only the crude proteoglycan part of S. aspratus showed the anti-coagulating activity, and this result might be due to the inhibition of intrinsic clotting system. Also, the crude proteoglycan part of S. aspratus showed the anti-complementary activity, and the $IC_{50}$ value was $50\;{\mu}l/ml$.

The sequence of ITS (partial 16S ribosomal DNA, complete ITS1, 5.8S ribosomal DNA and ITS2, and partial 28S ribosomal DNA) was analysed by PCR and autosequencing in Sarcodon aspratus. The ITS lenght of S. aspratus was 716 base pair. As this sequence compared with other reports on S. aspratus (ace No AF335110), the sequence variation based on nucleotide deletion and substitution was $1.8\%$. This nucleotide variation rate in same species was very higher than in other species. Also, the sequence varitation rates between this S. aspratus and S. imbricatus, and S. squamus were $8\%\;and\;10\%$, respectively. This results suggested that the high sequence variation of S. aspratus might be caused specific host and inhabitat environment which limited gene flow.

To investigate the effect of Sarcodon aspratus methanol extract on liver damage in benzo(a)pyrene (B(a)P)-treated mice, mice were divided into 4 groups of control, B(a)P, Sarcodon aspratus methanol extract and Sarcodon aspratus methanol extract-B(a)P. The activities of serum aminotransferase, cytochrome P-450 and hepatic content of lipid peroxide after B(a)P-treatment were increased than control, but those levels were significantly decreased by the treatment of Sarcodon aspratus methanol extract. On the other hand, the hepatic glutathione content and glutathione S-transferase activity were increased by the treatment of Sarcodon aspratus methanol extract. Also the activities of superoxide dismutase, catalase and glutathione peroxidase were decreased by the treatment of Sarcodon aspratus methanol extract. In addition cytochrome P-450 1A1 isozyme protein level, which was remarkably increased by B(a)P treatment from results of immuno blotting, was decreased by the treatment with methanol extract of Sarcodon aspratus. These results suggest that Sarcodon aspratus methanol extract have protective effect on liver damage by decreasing lipid peroxide and activities of free radical generating enzymes.

This study was carried out in order to produce useful material for the forest multiple use and forest protection by physico-chemical soil analysis of studied area in Sokwang-ri Forest Genetic Resource Protection Forest which was divided into in standard plots include Tricholoma matsutake and Sarcodon aspratus production forest. The result of physico-chemical soil analysis represented as following. The soil type of T. matsutake production forest was Dry brown forest soil(B1), while on the other hand the soil type of S. aspratus production forest was Moderately moist brown forest soil(B3). Between T. matsutake and S. aspratus production forest did not result in significant changes in soil pH(5.22-5.60) and soil depth(47cm), but available phosphorus, carbon, and nitrogen contents were different results. CN ratio of the fairy ring of T. matsutake was quite lower than that in S. aspratus production forests, which indicated that T. matsutake production forest was built up in the relatively immature soils which contain little organic matter. Generally, it was predicted that Pinus densiflora for. erecta forest succeeded to deciduous tree forest in stable soil environments. To conserve these T. matsutake and S. aspratus production forest, the contents of available phosphorous and exchangeable cation should be increased by continuous soil environment management and it should be established the secondary growth forests of old aged Pinus densiflora for. erecta trees as soon as possible.

The mineral contents of domestic and Chinese Sarcodon aspratus were analyzed for comparing the differences in the mineral contents according to the production sites. The mineral contents of 10 domestic and 10 Chinese S. aspratus were analyzed by using an atomic absorption spectrophotometer and an inductively coupled plasma mass spectrometer. The sodium, magnesium, potassium, and calcium contents of domestic S. aspratus were 170.3±44.0 mg/kg, 81.3±20.8 mg/kg, 1,123.8±274.3 mg/kg, and 12.1±4.1 mg/kg, respectively, while those of Chinese S. aspratus were 112.2±40.8 mg/kg, 297.8±20.9 mg/kg, 10,938.4±2,914.1 mg/kg, and 52.5±27.7 mg/kg, respectively. There were no significant differences in the micro mineral contents and hazardous heavy metal contents between domestic and Chinese S. aspratus, while there was a significant difference in the macro mineral contents between domestic and Chinese S. aspratus. Thus, the comparative analyses of the sodium, magnesium, potassium, and calcium contents of many domestic and Chinese S. aspratus are required to determine their production sites in the future.

Sarcodon aspratus (Thelephoraceae), a native mushroom distributed in Korea and Japan has been widely used as a traditional food and folk medicines. Two proteoglycan polysaccharides, named SAP-A and SAP-B were isolated from the fruitbody of S. aspratus. Their molecular weight were determined as 6184.9 D, and 25749.2 D, respectively, by maldi-tof ms. The composition of sugar and amino acid of these compounds was also determined. The SAP-A showed potent antitumor activity. The $ID_{50}$ value of SAP-A was 8.2 mg/kg/day for ICR mice transplanted with solid sarcoma-180, and the elongation of lifespan effect was 167.4% for ICR mice transplanted with ascitic sarcoma-180. Moreover, the elongation life-span effect of SAP-A increased dose-dependently.

The purposes of this study were to investigate enzyme components and its physiological activities of Sarcodon aspratus (Berk.) S. Ito which grows wildly in Korea, belonging to the family Thelephoraceae. The carpophores of the fungus was extracted with cooling distilled water and salted out by ammonium sulfate. The precipitate was purified by dialysing through visking tube against distilled water and then dissolved with pH 7.8 ammonia aqua, and the extract was filterated. The fraction of filtrate was obtained as light brown powder after lyophilization and determined proteolytic activity. Protease activity of Sarcodon aspratus (Berk.) S. Ito was about two-third of that of pepsin on casein by cup method. The proteolytic potency of this enzyme was found to be 500 unit/mg. This proved the efficacy of the mushroom when it was used as a folk medicine for treating indigestion of beef.

The antioxidative activity of various enzymatic extracts from Sarcodon aspratus (S. aspratus) was evaluated by measuring 1,1-diphenyl-2-picrylhydrazyl (DPPH), and alkyl radical scavenging activity using an electron spin resonance (ESR) spectrometer. For this study, the S. aspratus were enzymatically hydrolyzed by seven carbohydrases (Viscozyme, Celluclast, Dextrozyme, AMG, Promozyme, Maltogenase, and Termamyl) and eight proteases (${\alpha}$-chymotrypsin, Alcalase, Flavourzyme, Neutrase, papain, pepsin, Protamax, and trypsin). The DPPH radical scavenging activities of Viscozyme and pepsin extracts were the highest, and the half maximal inhibitory concentration ($IC_{50}$) values were 0.896 and 0.734mg/mL, respectively. The Celluclast and trypsin extracts showed the highest scavenging activities on alkyl radical, and their $IC_{50}$ values were 0.278 and 0.575mg/mL, respectively. The Celluclast extracts was decreased cell apoptosis in PC-12 cells against $H_2O_2$-induced oxidative damage. The findings of the present study suggest that enzymatic extracts of S. aspratus exhibit antioxidative activity against oxidative stress on PC-12 cells.
