  • This study was carried out to develop specific primers for PCR detection of Phellinus linteus. Diverse genomes of 15 Phellinus spp. including five Phellinus linteus isolates were fingerprinted by Primer Universal rice primer(URP)1F. The URP-PCR pattern differentiated P. linteus isolates from other phellinus spp. A polymorphic band(2.8 kb), which is unique for P. linteus isolates, was isolated and sequenced. Twenty four-oligonucleotide primer pairs were designed based on information of DNA sequence. The primer set(PLSPF2/PLSPR1) amplified single band(2.2 kb) of expected size with genomic DNA from seven Phellinus linteus, but not with that of other Phellinus species tested. The primers could be used identically in both DNA samples from mycelium and fruit bodies. This specific primers could offer a useful tool for detecting and identifying P. linteus rapidly.

  • A new synthetic medium was developed for the submerged mycelial cultures of Phellinus linteus. The medium for maximum mycelial growth of Phellinus linteus (3 days incubation, 28$^{\circ}C$, pH 5) consisted of (per 1 L): glucose, 90 g peptone, 10 g soluble starch, 10 g yeast extract, 3 g KH2PO4, 1 g MgSO4.7H2O, 1 g and CaCl2, 0.1 g. The concentrations of glucose, peptone, yeast extract, KH2PO4, MgSO4.7H2O, and CaCl2 were examined in the ranges of 10~90 g/L, 0~10 g/L, 0~15 g/L, 0~2 g/L, 0~1 g/L, and 0~0.5 g/L, respectively. The dry weight of mycelium in 3 days increased to 16.79 mg/mL using the new synthetic medium. The optimum temperature for mycelial growth of Phellinus linteus was 28$^{\circ}C$. The concentrations of KH2OP4, CaCl2, and yeast extract, which gave the maximum mycelial growth of Phellinus linteus, existed in the concentration ranges examined in this study. But, in the cases of other compositions (MgSO4.7H2O, peptone, and glucose), the mycelial growth of Phellinus linteus increased with the concentration in the ranges.

  • Phellinus linteus was examined on its immunostimulating activities using an in vitro imunization and plaque forming cell assay. When lymphocytes were exposed to the extract of Phellinus linteus, the number of antibody forming cell was increased. In in vitro plaque forming cell assay, the immunostimulating effect was about 4.8 and 5.0 times of unimmunized control in polyconal and T-independent antibody response, respectively. Especially, Phellinus linteus significantly increased the antigenicity of TNP-LPS used as T-independent antigen. But Phellinus linteus did now show a mitogenic effect on B-lymphcytes. These results suggest that immunostimulating activity of Phillinus lintues might be associated with a functional stimulation of B-lympohocyte involved in humoral immune response.

  • We investigated antitumor activities of the ethanol extract from mushroom Phellinus linteus and Phellinus baumii on mulberry, oak and elm. in vitro test, the ethanol extract of mushroom cultivated on oak of Phellinus linteus showed highest activities about SK-OV-3, HCT15, XF498, SK-MEL-2 and A549. SK-OV-3 cell line showed 100% cytotoxicity in 100 $\mu\textrm{g}$/ml and HCT15 (98.39%), XF498 (89.62%), SK-MEL-2 (84.07%) and A549 (79.92%) cytotoxicity respectively. Also $IC_{50}$ showed 3.99 $\mu\textrm{g}$/ml to SK-OV-3 cell line and HCT15 (4.37 $\mu\textrm{g}$/ml), A549 (5.48 $\mu\textrm{g}$/ml), SK-MEL-2 (6.72 $\mu\textrm{g}$/ml), XF 498 (6.88 $\mu\textrm{g}$/ml). As those results, cultivated oak of Phellinus linteus showed a very low $IC_{50}$ value against SK-OV-3, HCT15, XF498, SK-MEL-2 and A549 cancer cell lines.

  • 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.

  • Background: The chemical characteristics of the exo-secretion from Phellinus linteus (referred to as exo-secretion) including the compositions of amino acids and monosaccharides were investigated. In addition, cytotoxicity of the exo-secretion on 5 tumor cell lines derived from human cancers and its antitumor activity against ascitic sarcoma-180 cells were examined. Methods: The antitumor activity of exo-secretion from Phellinus linteus was determined by measuring parameters including tumor weight, life span of mice, chemotatic activity of leukocytes, counts of immune cells, and activity of cytokines. Results: The exo-secretion from Phellinus linteus showed no direct cytotoxicity to the five tumor cell lines tested, but it had a strong antitumor activity against sarcoma-180 cells in ICR mice as measured by tumor weight and life span of mice. The exo-secretion stimulated the chemotaxis of leukocytes and production of immune cells and cytokines. Conclusion: These results suggest that the exo-secretion from Phellinus linteus do not act as a direct cytotoxic substance to cancer cells but as an immunomodulator.

  • Phellinus linteus was artificially cultivated in kangwon province in Korea. The air-dried phellinus linteus was frozen in liquid nitrogen tank and powdered in jar. 10g of the powder was extracted with each 200g of ethanol, methanol, distilled water and 1,3-butylene glycol/distilled water 4 hours under refluxing and then the liquidextract was concentrated under reduced pressure. As a result of analysis by high performance liquid chromatography and thin layer chromarography, many kinds of sugar and flavonoids were detected. Also we knew that phellinus linteus' extract had a strong UV-ray absorption. In the efficacy test for applying to cosmetics, free radical scavenging effect was confirmed. As a result, 2% of sample was the most potent inhibitory effect and the free radical savenging activity, was 0.31%. This is more effective than any other meterial. In the test of antioxidative activity against lipid autoxidation, phellinus linteus' extract had a good effect by 46% while vitamine E was 42.3%. The immunological activity of phellinus linteus was showed through the activation of macrophage cell. Actually, phellinus linteus activated macrophage function of 1.1-1.8 times including nitrite production compared to control. The whitening effect of phellinus linteus was showed through the inhibition of tyrosinase activity, melanin biosynthesis of S. bikiniensis and B-16 melanoma cells. Phellinus linteus' extract was showed strong mushroom tyrosinase inhibitory activity with IC50 value of 0.5% and inhibited melanin biosynthesis with 28mm inhibition zone at 0.005%/paper disc in S. bikinniensis, a bacterium used as an indicator organism in this work. Also it inhibited melanin biosynthesis in B-16 melanoma cells with a minimum inhibitory concentration of 0.134%.

  • Based on the rDNA ITS sequences data, specific primer set for PCR detection of wood-decaying fungus Phellinus linteus was designed. The length of PCR products using designed primer set(SHF and SHR) was about 540 bp. Among 11 species, 17 isolates of Phellinus spp. including Phellinus linteus, P. pomaceus, P. spiculosus, P. baumi, P. pini, P. igniarius, P. gilvus, P. biscuspidatus, P. weirii, P. johnsonianus, P. robutus, and P. igniarius, seven isolates of Phellinus linteus showed about 540 bp-sized single band. This molecular technique could offer a useful tool for detecting and identifying Phellinus linteus.
