The low quality fresh ginseng was fermented by Phelinus linteus or Hericium erinaceum mycelium. This fermented ginseng was extracted by water at $100^{\circ}C$ or water with ultrasonification at $60^{\circ}C$. 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-$\alpha$ and IL-6 from human immune cells was enhanced as $3.53{\times}10^{-4}\;pg/cell$, $3.40{\times}10^{-4}\;pg/cell$ 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 $1.0\;mg/m{\ell}$ 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 $1.0\;mg/m{\ell}$. 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.

Low quality fresh ginseng was fermented by Pheliuus linteus mycelium at $22^{\circ}C$ for 30 days, then extracted by water solvent at $100^{\circ}C$ for 180 min. On human normal cell lines (HEK293), cytotoxicity was about 10% lower in adding extracts of the fermentation ginseng than that from low quality ginseng. The fermented extracts also inhibited the growth of several human cancer cells. Among them, respectively, digestive organs related cancer cells, such as human stomach adenocarcnioma and human epithelial adenocarcinoma were most effectively inhibited up to 85% and 90%, respectively. Then, selectivities were in the ranges of 3 to 5, compared to 2 to 3 from low quality fresh ginseng. Generally, fermented ginseng extract showed higher anticancer activities as well as higher DPPH radical sacavening activity, possibly due to high contents of total phenolic components as 6.96 mg/g. It was very interesting that the fermented ginseng contained very higher contents of ginsenoside-Rc+$Rb_2$, compared to others in low quality fresh ginseng because of partition digestion of mycelium growth. The results can tell that low quality fresh ginseng can be utilized by the fermentation with Pheliuus linteus mycelium.

잔나비 걸상 버섯 자실체와 균사체를 증류수와 에탄올로 추출하였고 이 중 보다 높은 생리활성을 보인 에탄올 추출물을 디에틸에테르와 크로로포름, 증류수층으로 분획하였다. 암세포 성장은 유방암의 경우 분획물의 활성이 다소 떨어졌으나 간암 세포에 대해서는 증가된 생육 억제율을 보였다. 가장 높은 생육억제율은 유방암세포에 대해 자실체 증류수추출물로 91.2%의 수치를 나타내었다. 세포 독성 실험에서는 증류수추출물보다는 에탄올추출물이 다소 높은 독성을 나타냈고 분획물은 클로로포름 분획물이 40%의 세포 독성을 보여 주었다. 돌연변이 유발억제 실험 에서는 MNNG의 돌연변이원성을 평가한 결과 크로로포름과 디에틸에테르 분획물이 가장 높은 억제 효능을 나타냈고 증류수 분획물은 상황 버섯 에탄올추출물과 유사한 효능을 보였다. 혈당강하 기능검색과 간기능 회복 검색에서는 분획물쪽에서 그 효능이 증가하는 경향을 나타냈다.
