Phellinus linteus (Hymenocaetaceae) has been used for the treatment of gastric cancer, noninsulin dependant diabetes, diarrhea, and menstrual irregularity. The antioxidative effect of cultivated fruit body of Phellinus linteus on low density lipoprotein oxidation was investigated. The MeOH and water extracts were examined by TEARS assay on human plasma LDL in vitro system. The MeOH ex. showed antioxidative activity, and then was fractionated into Precipitates, Water Insoluble fr., Water fro and ether fro The results showed that the lipophilic fractions, Water Insoluble fr. and Ether fr. of cu 1-tivated fruit body of Phellinus linteus, inhibited the oxidative modification of LDL.

본 연구에서는 ${O_2}^-,{\cdot}OH$ radical, NO, $ONOO^-$ 자유라디칼을 유발시키는 in vitro assay system과 free radical-induced oxidative stress에 의한 단백질 손상에 대한 진흙버섯속에 속하는 상황버섯 물 추출물의 항산화 효과를 측정하였다. 상황버섯 물 추출물의 ${O_2}^-,{\cdot}OH$ radical, NO, $ONOO^-$ 자유라디칼 억제효과에서는 실험에 사용된 양성 대조물 보다는 낮게 나타났으나 모든 실험계에서 대조군에 비해 뚜렷하게 자유라디칼 소거효과를 나타냈다. 또한 상황버섯 물 추출물은 산화적 스트레스에 의한 단백질 손상 억제효과에서도 대조군에 비해 명확한 저해효과를 나타냈다. 그러므로 상황버섯의 항산화 효과는 상황버섯의 약리학적 효능을 설명하는데 중요한 기초 자료라고 사료된다.

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.

To develop new functional materials, Saccharina japonica (S. japonica) was cultivated with Phellinus linteus (P. linteus) mycelia by solid culture. S. japonica was fermented with P. linteus mycelia. The various radical scavenging activities of extracts of fermented S. japonica with P. linteus mycelia (FSPM) were investigated and compared to the antioxidant capabilities of unfermented S. japonica and P. linteus mycelia. The antioxidant activities of FSPM extracts were evaluated using ferric reducing antioxidant power (FRAP) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity. FSPM showed stronger free radical scavenging abilities than P. linteus mycelia or S. japonica alone. These results indicate that fermentation of S. japonica changes its chemical nature and could provide beneficial antioxidant effects.

This study was peformed to determine the antioxidant, antimicrobial activity and antifungal of the cambodian mushroom, Phellinus linteus, in various concentrations from the mushroom extracts. It's extracts were found to cause significant free radical scavenging effects on DPPH (1,1-diphenyl-2-picrylhydrazyl). This extracts exhibited in vitro broad-spectrum antimicrobial activity of Gram-negative, Gram-positive bacteria and without antifungal activity. On the other hand, the extracts had not significant hemolytic activity against human red blood cells. These results indicate cambodian mushroom, Phellinus inteus having antioxidant and antimicrobial activity without hemolytic activity maybe useful as therapeutic agents.

본 연구에서는 버섯으로부터 새로운 항비만 치료(예방) 효과를 갖는 물질을 추출, 정제하여 그 특성을 규명하고, 이를 기능성식품 개발의 소재로 용용하고자 lipase 저해 활성이 높은 상황버섯(Phellinus linteus)의 lipase 저해 물질을 각종 chromatography로 정제 하였다. 먼저 상황버섯(Phellinus linteus) 자실체 추출물에 대한 용매 계통분획을 실시하여 저해 활성이 가장 높은 에틸아세테이트 추출물을 얻었고 이를 3차례의 sillicas gel column chromatography와 분취용 HPLC를 실시하여 $IC_{50}$값이 175 ng의 lipase 저해활성을 가진 연한 연두색 분말의 정제된 lipase 저해 물질을 얻었다. 정제한 lipase 저해물질을 일련의 NMR spectrometry를 실시한 결과 분자량이 523.06 Da으로 추정되었고 225.1 nm에서 최대 흡수 파장을 가진 물질이었다.

This study was performed to determine the antimutagenic and cytotoxic effect of the Phellinus linteus methanol extract on Salmonella typhimurium TA98, TA100 and human cancer cell lines. In the Ames test, methanol extract of P. linteus alone did not exhibit any mutagenicity but showed substantial inhibitory effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine(MNNG), 4-nitroquinoline-nitroquinoline-1-oxide(4NQO), 3-amino-1,4-dimethyl-5H-pyrdo[4,3-blindol(Trp-P-1) and benzo(α)pyrene(B(α)P). The methanol extracts of P. linteus(200㎍/plate) showed approximately 78.3%, 78.7% and 88.1% inhibitory effect on the mutagenesis induced by 4NQO, Trp-P-1 and B(α)P. The anticancer effects of P. linteus extract against human breast adenocarcinoma(MCF7), human lung carcinoma (A549), human fibrosarcoma (HT1080), human hepatocelular carcinoma (Hep3B) and human epitheloid carcinoma (HeLa) were investigated. The treatment of 1mg/mL P. linteus extracts had the highest cytotoxicity against MCF7 (92.0%), followed by Hep3B (84.9%), A549 (84.2%) and HT1080 (82.9%). In contrast 1mg/mL treatment of P. linteus extracts had only 10∼40% cytotoxicity on normal human liver cell (WRL68).

The antioxidant and anticancer activities of Phellinus linteus, Inonotus obliquus, and Pleurotus ostreatus according to extraction methods were measured. The contents of polyphenolic compounds were higher in fermented extracts than those in water extracts. The contents were 192.4mg/100 $m{\ell}$ for Inonotus obliquus vinegar, 186.9 mg/100 $m{\ell}$ for Phellinus linteus vinegar, and 156.5 mg/100 $m{\ell}$ for Pleurotus ostreatus vinegar, respectively. EDA(electron donating ability) in Phellinus linteus that was highest among mushrooms was 83.9% in the water extract and 96.8% in the fermented extract. The growth of stomach cancer cells, SNU-719 was inhibited 62.4%, 65.5%, and 53.0% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, respectively and also the growth of liver cancer cells, Hep3B was inhibited 67.1%, 68.3%, and 57.6% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, while the growth of normal cell, DC2.4 was not affected. Even though Phellinus linteus and Inonotus obliquus showed higher inhibition in cancer cell growth, Pleurotus ostreatus can be efficiently used for antioxidant and anticancer activities due to their cheap price in the market.
