Russula compacta, a wild mushroom, belongs to Russulaceae, Russulales of Basidiomycota. This study was conducted to evaluate the free radical scavenging, anti-inflammatory, anticholinesterase and anti-α-glucosidase effects from fruiting bodies of R. compacta extracted with methanol and hot water. In 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging effects, the methanol and hot water extracts showed good scavenging effects comparable with positive control, BHT. The chelating effect of methanol and hot water extracts of the mushroom were significantly higher than the positive control, BHT. The reducing power of the methanol and hot water extracts of the mushroom were lower than the positive control at the concentrations tested. In the HPLC anaysis of phenolic acids profile of the mushroom extract, 7 phenolic acids such as gallic acid, vanillin, rutin hydrate, resveratol, quercetin formononetin, and biochanin-A were detected. Nitric oxide (NO) production in lipopolysaccahride (LPS) activated RAW 264.7 cells was inhibited by 1.5-fold with the treatment of methanol extract when compared with the control. In the anti-cholinesterase activity assay, the methanol extract inhibited the acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) effects by 73.9% and 81.05% at the 1.0 mg/mL concentration, whereas galanthamine, the standard drug, inhibited the AChE and BChE activities by 97.80% and 81.12%, respectively at the same concentration. The methanol and hot water extracts of the mushroom inhibited the α-glucosidase activity by 55.44% and 62.00%, respectively at the 2.0 mg/mL concentration, while acarbose, the positive control inhibited the α-glucosidase activity by 81.81% at the 2.0 mg/mL concentration. From the experimental results, the fruiting bodies of R. compacta contained natural antioxidant, anti-inflammatory, anti-cholinesterase, and anti-diabetic substances, which might be used for health foods.

Roll milled- and nano-powders were prepared from the freeze dried fruiting bodies of Hericium erinaceum and their hydration properties such as water solubility index, swelling capacity, water holding capacity, and water sorption isotherm were compared. Water content in freeze dried Nano-powder of Hericium erinaceum fruiting body was 8.17%. Nano-powder has higher water solubility index compared to roll mill powder by 58.41% and 39.06%, respectively. In the same way, swelling capacity of nano-powder was 10.21ml/g where as roll mill powder has only 4.42ml/g. In contrast, water holding capacity of nano-powder (3.87g/g) is lower than that of roll mill powder (6.81g/g). Water sorption isotherm of these powders was compared and the result shows no big difference at low relative humidity (below75%).

Lentinus edodes is a popular edible mushroom in South-East Asia. This study was initiated to evaluate the antioxidant activities, tyrosinase inhibitory effects on the fruiting bodies of L. edodes extracted with acetone, methanol and hot water. The antioxidant activities were performed on β-carotene-linoleic acid, reducing power, 1,1-diphenyl-2-picrylhydrazyl free radical scavenging, and ferrous chelating abilities. In addition to this, phenolic acid and flavonoids contents were also analyzed. Methanolic extract of L. edodes showed the strongest β-carotene-linoleic acid inhibition as compare to others extracts. At 8 mg/ml, hot water extract showed a high reducing power of 0.96. The scavenging effects on 1,1-diphenyl-2-picrylhydrazyl radicals, acetonic extract was effective than other extracts. The strongest chelating effect (86.45%) was obtained from the acetonic extract at 1.0 mg/ml concentration. Antioxidant activities of the extracts from the fruiting bodies of L. edodes were increased with the increasing concentration. After application of reverse phase high performance liquid chromatography, coupled to a diode array detector and electrospray ionisation mass spectra, four phenolic compounds namely, naringenin, hesperetin, formononetin and biochanin were identified from acetonic extract. Tyrosinase inhibition of acetonic, methanolic, and hot water extracts of L. edodes were increased with the increasing of concentration. Results revealed that acetonic and methanolic extracts showed good, while hot water showed moderate activities of the tyrosinase inhibition at the concentration tested. This study suggests that fruiting bodies of L. edodes can potentially be used as a readily accessible source of natural antioxidants.

To understand the saccharide contents and quantity of winter mushroom (Flammulina velutipes) according to its growth temperature, we measured the saccharide contents at different growth temperature. In our results, the saccharide of its fruiting body turned out to be mainly composed of xylose, trehalose and mannitol in all treatments. In the other hand, Ribose, myo-inositol and sucrose were detected in some treatments. The quantity of trehalose decreased as the growth temperature increased with a variation of its quantity depending on the isolates used in the experiments. In the case of xylose and mannitol, detected in all treatments, the pattern of their quantities was not possible to be profiled and the pattern might be largely depending on the isolates. However, the quantities of xylose and mannitol were largely in a direct proportion and the fluctuation of their quantities was congruent with the exception of ASI 4103, ASI 4166 and ASI 4065. The xylose quantity of ASI 4103 and ASI 4166 increased until the temperature was up to 10℃ and decreased when the temperature was above 10℃. That of ASI 4065 decreased as the temperature rose and increased when above 13℃. The mannitol quantity of ASI　4065 and ASI 4166 decreased until the temperature was up to 10℃ and increased when the temperature was above 10℃. That of ASI 4103 increased as the temperature rose and decreased when above 13℃.

Phellinus sp. are assigned to the Basidiomycotina, Hymenomycetes, Aphyllophorales and Hymenochaetaceae, and have been shown containing various bioactive substances including triterpenoids, polysaccharides and flavones[1]. Traditional Chinese herbalists believe that Phellinus species are effective in treating many gynecopathic ailments[2] and are also reported to exhibit other pharmacological functions including tumor cell inhibition, antioxidant activity and anti-hepatic fibrosis effects[3]. Polysaccharides of Phellinus sp. has been reported to possess antitumor activities and inhibit tumor recrudescence and metastasis. There are little studies comparing the chemical composition and biological activities difference among polysaccharides from different Phellinus sp and little report about the pure polysaccharide structure analysis. In this study, eight kinds of crude polysaccharides were extracted from Phellinus fruit bodies and their chemical composition and bioactivities were researched. The polysaccharide and protein contents of eight crude polysaccharides had a certain extent differences. Monosaccharide composition and content of amino acids also existed some differences in eight crude polysaccharides. Eight different polysaccharides all showed enhancing splenocyte proliferation effect in vitro. PB-10P and JSHP had high cell proliferation rates with 50㎍/ml concentrations. The results indicated in some extent the immune activity of crude polysaccharides were correlation with the polysaccharide and protein content and composition of each sample. The crude polysaccharides of P. igniarius were further isolated and purified using DEAE Sepharose F. F. and gel-filtration chromatography (Sephacryl S-100-500 ）repeatedly. Five water-soluble homogeneous polysaccharides (P60w1、P60s1、P1SP1、P10SP1and P100SP1) were obtained. Lack of absorption at 280 nm and 260 nm by UV scanning indicated that contained no protein and nucleic acid. HPLC produced a single symmetrical peak, indicated homogeneity and their molecular weigh were 1.71×104 Da、2.07×104 Da、1.48×104 Da、2.20×104 Da and 2.56×104 Da respectively. Structural of P60w-1 were determined using sugar and methylation analysis combined with 1H and 13C NMR spectroscopy, including COSY, TOCSY, NOESY, HSQC and HMBC experiments. The effect of P60w-1 on tumor growth was examined using subcutaneously transplanted H22 and Lewis Lung Carcinoma (LLC) tumor mouse models. Cyclophosphamide or Coriolus versicolor polysaccharopeptide served as positive controls in evaluating tumor response. Results showed that P60w-1 at the most effective dose of 100 mg/kg inhibited the growth of H22 and LLC by 48% and 37%, respectively.
