The purpose of this study is to compare the morphology, general composition, elemental composition and mineral contents of Phellinus linteus, Phellinus baumii and Phellinus gilvus. In the scanning electron microscopy, P. gilvus and P. linteus had a similar shape. In the elemental composition, all of the three Phellinus spp. showed similar percent for the analyzed components. In the general composition, the water content of P. linteus. P. baumii and P. gilvus were 13%, 15% and 10%, respectively. The dietary fiber of three Phellius spp. showed more than 30%. The range of vitamin C and protein content was 1.5-2.1 g% and 3.63-3.73 g%. respectively. In mineral analysis, P. baumii of the three Phellinus spp. has the highest calcium concentration (1,135 ppm). From the above results, P. linteus. P. baumii and P. gilvus did not show any differences in the general composition and elemental composition.

For artificial cultivation of Phellinus baumii, we have conducted a study on cultural characteristics and condition of fruitbody formation in sawdust cultivation. Mycelial density and incubation rate were higher in oak sawdust+rice bran (4 : 1) medium than oak sawdust 100% medium. However, primordia and fruitbody formation were higher in oak sawdust 100% medium than rice bran added medium. Bigger bottle capacity (1,100 ml) resulted in a little higher yield and more biological efficiency than 850 ml bottle.

High temperature and natural sun light are considered as the core conditions for high quality and large quantity of Phellinus baumii production. However still now on there has been a mistake of excessively cutting off the natural light by spreading the closing nets on the mushroom cultivating house. For an example there are many houses where the closing nets under the roofs be extended to cover the sides of the houses, which way prevents the mushrooms in the houses from receiving sufficient natural sun light and getting the temperature sufficiently to grow so that the quantity and quality of the produced mushrooms are lowered even though the mushrooms can grow in those conditions. In order to avoid this mistake, the closing nets must be placed on the roofs of the houses only without dropping them to cover the sides. Further more when the closing nets are placed triply at the beginning stage of Phellinus baumii's growth in the house, the nets restrain the internal temperature of the house going up and intercept the natural bright light flowing into the house so that the growing tardiness occur to the Phellinus baumii. Therefore the roof only must have been covered by the closing net for 65% cutting off the light until May, and then covered by double folded the net for June, triple folded the net for July and August, double folded the net for September, and the single net for October. When the ventilation in the house has been maintained until the house tightly balloon out through controling lifting force of internal air, the Phellinus baumii can grow well while the bed logs themselves aren't dried out. Marketing is also very much important as well as increasing quality and quantity of Phellinus baumii production.

Various Phellinus species (Hymenochaetaceae) including P. linteus, P. baumii, P. pini, and P. igniarius of domestic and foreign products, were examined by gas chromatography to validate their composition of crude polysaccharides. The crude polysaccharide fraction, which is known to be one of the physiologically active fractions, were prepared by a cold ethanol precipitation method and the yield of the crude polysaccharide fractions of P. linteus, P. baumii, P. pini, and P. igniarius were 15.0%, 5.1%, 6.3% and 5.7%, respectively. The total monosaccharide amount of the crude polysaccharide fraction of P. linteus was 148.713 mg/g (dry weight of mushroom) while those of P. baumii, P. pini and P. igniarius were 29.022 mg/g, 29.222 mg/g and 1.546 mg/g, respectively. Although the major monosaccharide of all Phellinus mushrooms was glucose, there were remarkable differences in the absolute quantity of each monosaccharide. P. linteus included plenty of monosaccharides except mannose and ribose in comparison with P. baumii and P. pini. The absolute quantities of monosaccharides of P. baumii and P. pini were nearly similar except arabinose. The total monosaccharides of P. igniarius were minimal, but the portions of galactose and mannose in P. igniarius were greater than in the other species.

Objective : Phellinus spp. mushroom is an object of interest because it has excellent anticancer effect. Owing to the similalarities in the morphology, Phellinus linteus and Phellinus baumii are often used as same Sang Hwang Mushroom in the Korean market.. The quality control for mushrooms is needed because there are many differences in the efficacy according to cultivation method and cultivation area. Therefore, a reliable authentication method of these herbal medicine is necessary to compare and measure the amount of beta-glucan which is known to have a hypoglycemic effect, from the mushrooms collected in various regions Methods : 7 samples of medicinal mushrooms supplying phellinus spp. were collected in Korea, China and Cambodia. We investigated the hardness, colors, extract ratio, ${\alpha}-amylase$ and ${\alpha}-glucosidase$ inhibitory activities, glucose transporter 4 (GLUT-4) expressions of water extracts from Phellinus spp and also MTT assay were examined for cell toxicity. Results : The results revealed that Phellinus spp.water Ext.inhibited ${\alpha}-glucosidase$ activity. glucose transporter 4 (GLUT-4), the key insulin signaling pathway transcription factor, was remarkably increased by the Phellinus baumii water extract Conclusions : These results suggest that The more yellowish the mushroom is, the lower the hardness, the more the content of ${\beta}-glucan$ is proportional. Because the more ${\beta}-glucan$, the greater the effect of hypoglycemia. compared to the hypoglycemic effect, Phellinus Baumii grown at hanging on selves for 7 month in the green house is the best.

Specific primer sets based on ribosomal DNA(rDNA) internal transcribed specer(ITS) sequences were designed for rapid detection of Phellinus linteus and P. baumii. Polymerase chain reaction(PCR) with these primers produced unique bands for each Phellinus species. The annealing temperature range is from $40^{\circ}C\;to\;55^{\circ}C$. The length of PCR products(P. linteus and P. baumii) using designed combinative primer sets of PL1F, PL2R, PB1F, PB2R, ITS5F and ITS4R, were from 520 by to 730 bp. Fifteen strains of Phellinus species including P. linteus, P. baumii, P. weirianus, P. johnsonianus, P. rhabarberinus, P. pini, P. gilvus, P. igniarius, P. nigricans and P. laevigatus were examined in this study. Five strains, including two isolated strains of P. linteus(MPNU 7001 and MPNU 7002), and two isolated strains of P. baumii(MPNU 7004 and MPNU 7005) were shown to have about 520 bp (PL1F-PL2R), 700 bp (TTS5F-PL2R) and 600 bp (PB1F-ITS4R) -sized PCR single bands respectively. This molecular genetic technique provided a useful method for rapid detection and identification of P. linteus and P. baumii.

This study was carried out to identify the phylogenetic relationship of Phellinus species and to know its distribution by comparing the DNA sequences of internal transcribed spacer regions(ITS1 and IST2) and 5.8S ribosomal DNA (rDNA) repeat unit. The Phellinus species had their specific sequences in IST1 and 2 regions depending on suedes. The comparison of the ITS sequences of standard strains indicated that the sequences of ITS1 were more variable than those of ITS2. Nine strains of the commercial products of Phellinus species used in this study were identified as P. lintues, P. baumii, P. igniarius, and P. pini. Most of commercial species were P. pini and P. baumii, and P. gilvus was not found. Also, P. linteus was only found in form of mycelial culture rather than fruiting body. Moreover, the species-specific primers were designed based on ITS sequence data. Each species-specific primers were bound in P. lintues(ITSF-PL2R), P. baumii(PB1F-ITS4R), P. igniarius(IF1-IR3), P. pini(PF1-PR3), and P. gilvus(GF2-GR4), respectively. These primer sets would be useful fer the detection of specific-species among unidentified Phellinus species rapidly.

The fruiting bodies of Sanghwang mushrooms, Phellinus linteus HN1009K (PLH) and Phellinus linteus (Korea Sanghwang, PLK), and Phellinus baumii (Jangsu Sangwhang, PB), were extracted with 70% methanol. The methanolic extracts of different concentrations ($5-200{\mu}g/ml$) showed inhibitory effects of 20-95% on plated aggregation induced by collagen (2.5 ug/ml), ADP (10 uM), and thrombin (0.1 U/ml). The PLH, PLK, and PB extracts (200 ug/ml) reduced ATP release from ADP-activated platelets by 50-60%. These results suggest that the methanolic extracts from Sanghwang mushrooms inhibit platelet aggregation.
