To produce bioactivity-strengthen medicinal herbs, the 36 medicinal herbs which have antioxidation or blood circulation activity, were solid fermented using Phellinus baumii mycelium. Most of medicinal herbs, except Chrysanthemum indicum (flower), Zizyphus jujuba Miller (fructus), Aconitum koreanum R. Raymond (root), Magnolia denu-data (flower), and Polygonatum sibiricum Redt (root bark), showed good fermentation at $25^{\circ}C$ for 20 days under 90% of relative humidity. The poor fermentations of the herbs could be explained by lack of nutrient, structural rigidity, and the content of antifungal substance. After fermentation, the average water content of herbs were increased to $67.21{\pm}11.43%$ from $30.84{\pm}15.67%$, but the average pH and average methanol extraction ratio were slightly decreased to $11.16{\pm}7.06%$ and $4.83{\pm}0.73$ from $13.91{\pm}12.22%$ and $5.06{\pm}0.87$, respectively. The analysis of thrombin inhibition and DPPH scavenging activity of the methanol extracts of herbs showed that thrombin inhibition activities of the fermented Drynaria fortunei Kunze, Melia azedarach var. japonica, Prunus persica and Orostachys japonicus, and DPPH scavenging activities of the fermented Polygala tenuifolia, Scrophularia buergeriana, Angelica dahurica, Drynariafortunei Kunze, Cyperus rotundus, and Boschniakia rossica were increased as compared with those activities of non-fermented its cognate herbs. Our results suggest that the production of bioactivity-strengthen medicinal herbs is possible by solid fermentation of Phellinus baumii mycelium, as fermented Drynaria fortunei Kunze showed increased antioxidant and thrombin inhibitory activities than those of non-fermented herbs.

Novel Phellinus linteus HN1009K (HK1009) has been characterized on speedy mycelial growth and yearly artificial cultivation. In this study, antioxidant and anti-inflammatory activities of ethanol extract from mycelium and fruiting body of P. linteus HN1009K (HK1009) were compared to those of P. linteus (PL, Korea Sangwhang) and P. baumii (PB, Jangsu Sanghwang) as controls. HK1009 extract showed higher DPPH free radical scavenging activity in both mycelial and fruiting body samples than those of PL and PB. However, in xanthine oxidase assay, antioxidant effect was highly measured on mycelial samples of PL and HK1009. Mycelial extract of HK1009 induced high inhibitory effect on LPS-induced nitric oxide (NO) production in RAW264.7 cells comparing to PL and PB without toxicity on the cells. The results suggest that P. linteus HN1009K possesses superior antioxidant activity and anti-inflammatory effects.

This study was carried out to investigate the anti-proliferative activity of solid-state fermented medicinal herbs which include Phellinus baumii. Methanol extracts were prepared from 36 different medicinal herbs and their fermented counterparts. These extracts were used to treat human colorectal HCT116 cell, human embryonic kidney cell HEK-293, pre-adipocyte cell 3T3-L1, and pre-osteoblast cell MC3T3-E1 for 24 hr. At a concentration of 100 ${\mu}g/ml$, the extracts of Amomum villosum, Cnidium officinale Makino, Dendrobium moniliforme, Dictamnus dasycarpus, Diospyros kaki Thunb, Eucommia ulmoides Oliv, Ginkgo biloba L, Magnolia denudata Desrousseaux, Orostachys japonicus, Panax notoginseng, Pharbitis nil Choisy, Polygala tenuifolia and Trichosanthes kirilowii (seed) led to a < 50% decrease in cell proliferation, and mycelium of P. baumii showed a 46.3% decrease in cell proliferation. Meanwhile, the extracts of the 25 fermented herbs showed similar anti-proliferative activities compared to those of individual non-fermented herbs. However, the extracts of the fermented Drynaria fortunei Kunze (1), Lycium chinense Mill (2), Fritillaria thunbergii Miquel (3) and Prunus persica showed increased anti-proliferative activity. The $IC_{50}s$ of (1), (2) and (3) were especially decreased to 28, 85 and 80 ${\mu}g/ml$ from 394, 917 and 149 ${\mu}g/ml$, respectively. Furthermore, the cytotoxicity of the extracts of fermented (1), (2) and (3) against HEK-293, 3T3-L1, and MC3T3-E1was negligible up to 200 ${\mu}g/ml$. These results suggest that solid-state fermentation using the mycellium of P. baumiiproduce potential anti-cancer agents or strengthen the bioactivity of medicinal herbs.
