B16F10 cell 500 ug/mL 농도로 처리했을 때, 노루궁뎅이균사발효율무 열수추출물 은 8.9 μM의 NO 생성율을 보여, 율무 추출물(10.6 uM) 의 NO생성율 보다 낮은 NO 생성율을 나타내었다. 10, 30, 50, 100, 200, 300 및 500 mg/mL 모든 농도에서 율무 열수추출물보다 노루궁뎅이균사발효율무 열수추출물이 유의적으로 tyrosinase 및 melanin 생성을 억제함을 확인 할 수 있었다. 노루궁뎅이균사발효에 따른 DPPH radical 및 ABTS radical 소거활성 측정결과 노루궁뎅이 균사발효 율무열수추출물이 율무 열수추출물보다 항산화 효과가 높음을 확인하였다. 따라서 추가적인 연구를 통해 노루궁뎅이균사발효 율무열수추출물은 기능성식품 원료와 식품 첨가물, 화장품 산업에 이용될 수 있을 것으로 생각된다.

To enhance the physiological activity of the Rhynchosia volubilis (RV), R. volubilis (RVHE-A) and R. volubilis-added herbal powder (RVHE-B) were fermented with a solid state culture of Hericium erinaceum mycelia (HE). The total isoflavone contents of the non-fermented RV-A (489.9 μg/g) and RV-B (571.1 μg/g) were remarkably increased in fermented RVHE-A (1,836.4 μg/g) and RVHE-B (1,276.7 μg/g). In particular, aglycone isoflavones such as daidzein and genistein were significantly higher in the RVHE-A than any other sample. When hot-water (HW) and EtOH extracts (E) were fractionated from the RV and RVHE, both extracts from the RVHE-A were higher than those from the RV-A in total polyphenol and flavonoid contents. However, the RVHE-B-HW showed a lower polyphenol and flavonoid content level than did RV-B-HW. RVHE-A-HW and -E also had more potent ABTS radical scavenging activity than any extract from the non-fermented RV and other ferments (RVHE-B). In the meanwhile, RVHE-A-HW potently stimulated the production of macrophage activation-related cytokines such as TNF-α, IL-6 and IL-12 (841.7±71.3 pg/mL, 3.9±0.1 ng/mL, 179.3±30.2 pg/mL) from peritoneal macrophage more than RV-A-HW (92.5±1.5 pg/mL, 0.1±0.0 ng/mL, 37.4±5.4 pg/mL) as well as RVHE-B-HW (557.0±21.3 pg/mL, 1.8±0.0 ng/mL, 90.0±10.0 pg/mL). However, all the EtOH extracts did not show significant activity. In addition, the RVHE-A-HW showed a significantly higher intestinal immune system modulating activity through Peyer’s patch and GM-CSF production than did any other extract from RV and RVHE-B. In conclusion, these results suggest that the fermented R. volubilis with H. erinaceum mycelia possesses a possible use as an industrial application as functional food or material.

본 연구에서는 뽕잎(Morus alba)을 노루궁뎅이 버섯균사체(Hericium erinaceum)로 발효시킨 열수 추출물(MA-HE)의 항산화 활성을 확인하고자 하였다. MA-HE의 항산화 활성을 DPPH radical, ABTS radical 소거활성 측정을 통해 알아보았다. 그 결과 DPPH radical 소거활성은 500 μg/mL 농도에서 61.73%, ABTS radical 소거활성은 250 μg/mL 농도에서 97.39%로 나타났다. MA-HE은 DNA의 산화적 손상을 효과적으로 억제하였다. 또한 생체고분자물질인 사람의 혈청단백질의 산화적 손상을 억제하였다. 세포에 H2O2를 처리하였을 때 세포생존율에 비하여 발효물을 100 μg/mL 농도로 전 처리한 세포생존율은 8% 증가했으며, 발효물을 50 μg/mL 농도로 처리했을 경우 세포 내 활성산소의 축적이 유의적으로 감소되었다. 본 연구 결과는 MA-HE이 항산화 활성을 가지고 있으며 산화적 스트레스에 의해 야기되는 세포 독성에 대한 보호 작용도 뛰어난 것으로 사료되었다.

본 연구는 mushroom complete medium(MCM) 액체배지에 수삼 추출물(GE, 65°Bx)을 첨가하여 면역활성이 증진된 노루궁뎅이버섯(Hericium erinaceum) 균사체를 배양하고, 균사체로부터 활성다당성분을 분획하고자 하였다. MCM에 대하여 GE를 5, 10과 15%(v/v) 첨가한 액체배지에서 균사체를 배양하고, 각각의 조다당획분(HE-GE-5-CP, HE-GE-10-CP와 HE-GE-15-CP)으로 분획하여 면역활성을 측정한 결과, HE-GE-10-CP는 HE-GE-5-CP와 HE-GE-15-CP보다 높은 활성을 나타내었으며, GE를 첨가하지 않은 MCM에서 배양된 균사체 조다당획분(HE-CP)보다 유의적으로 증진된 면역활성을 나타내었다. 또한, HE-GE-10-CP의 DEAE-Sepharose CL-6B 분획물 중 가장 높은 활성을 나타낸 HE-GE-10-CP-II획분은 대조군인 HE-CP의 어떠한 획분보다도 유의적으로 높은 면역활성과 암 전이 억제활성을 나타내었다. 한편, 활성획분인 HE-GE-10-CP-II는 arabinose, rhamnose, galactose, glucose와 uronic acid(molar ratio; 0.34:0.26:0.99:1.00:0.39)로 구성되어 있으나, 대조군인 HE-CP의 동일용매 용출획분으로서 HE-GE-10-CP-II보다는 활성이 낮은 HE-CP-II는 fucose, mannose, galactose와 glucose(molar ratio; 0.32:0.55:1.00:0.96)를 함유하여 다른 구성당 분포를 나타내었다. 따라서 노루궁뎅이버섯 균사체 액체배양에서 수삼 추출물 첨가는 균사체의 구성당 변화를 통한 면역활성 증진에 관여하는 것으로 사료되어 기능성 소재 개발에 유용할 것으로 사료된다.

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%). However, a high relative humidity above 75%, these two kinds of powder showed comparable difference. At 84.34% relative humidity, roll mill powder has 30.41% of moisture content compared with 47.64% of nano-powder, and at the relative humidity of 97.3%, the moisture content of roll mill and nano-powder are 37.64% and 91.06% respectively.

This study was conducted to investigate the physiological activities of the ethanol extracts from 3 different strains of Hericium erinaceum. In addition, the β-glucan and polyphenol contents from these strains were also measured. As a result, total polyphenol contents were the highest in 1ho(39.07 mg%) strain and lowest in 2ho(17.59 mg%). β-glucan contents ranged from 17.69 to 18.26%. In the physiological activities, Inhibition effects of DPPH radical and Nitrite ranged from 3.29 to 9.6% and 1.52 to 5.27%, respectively. Inhibitory effects of nitric oxide production ranged from 23.72 to 33.47%. The highest inhibitory activities on α-amyloglucosidase activity and angiotensin I converting enzyme were 39.30% and 14.10%, respectively. Lastly, the cytotoxic activities of ethanol extracts from all the strains on A549, HT-29 and HeLa cell was shown the highest effect in A549 cell.

This study was carried out to investigate neuronal protective activity of fruiting body of Hericium erinaceum. In order to search the effective active compound against amyloid beta peptide-induced oxidative stress on neuronal cells, rat pheochromocytoma cells (PC12), Extracts of Hericium erinaceum were screened and evaluated using both the 2’,7’-dichlorofluorescin diacetate assay (DCF-DA), and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. According to above assays, Solvent partitions of extracts were selected for further purification and isolation of anti-Alzheimer’s disease compound as it exerted the highest protective effects against hydrogen peroxide (H2O2)-induced oxidative stress.

The waste substrate from sawdust based cultivation of Heicium erinaceum was reused. This process was conducted three times. Even when the waste substrate was reused at three times, the yield of fruiting bodies was equal to that of fresh medium. However, the yield of the 1st-waste substrate was the best of all waste substrate media and the yields of waste substrate media deceased with recycling times. The yield of the 1st or the 2nd waste substrate medium increased by 1.3-1.4 times compared with that of the fresh medium. The content of low molecular α-glucan and β-glucan of the 1st or the 2nd waste substrate medium increased and C-N ratio of the 1st or the 2nd waste substrate medium decreased. These results suggest that low molecular glucan and N sources contribute to increasing fruiting bodies. It was clear that the 1st and the 2nd waste substrate were useful for the cultivation material of Heicium erinaceum.

The low quality fresh ginseng was fermented by Phelinus linteus or Hericium erinaceum mycelium. This fermented ginseng was extracted by water at 100℃ or water with ultrasonification at 60℃. Total phenolic compounds was improved by ultrasonification extraction process, compare to conventional water extraction. All extracts enhanced the growth of human B and T cells, showing 2.68 times and 3.43 times higher, respectively, than the control. The secretion of TNF-α and IL-6 from human immune cells was enhanced as 3.53×10-4 pg/cell, 3.40×10-4 pg/cell by adding H. erinaceum mycelium fermented ginseng. H. erinaceum mycelium fermented ginseng yielded higher nitric oxide production from macrophage than Lipopolysaccharides (LPS). The cytotoxicity on human normal kidney cell (HEK293) was as low as 20.5% in adding the maximum concentration of 1.0 mg/ml of fermented ginseng. Generally, the extracts from ultrasonification extraction process showed 10% lower toxicity than that by conventional process. H. erinaceum mycelium fermented ginseng had the highest anticancer activity on human lung cancer and stomach cancer cells as 69.33% and 75.32%, respectively at 1.0 mg/ml. It can be concluded that, in general, H. erinaceum mycelium fermented ginseng has relatively better immune and anticancer activities than P. linteus fermented ginseng. Expecially, the extracts treated with ultrasonification had higher activities than that from conventional extraction process.
