The aim of this study was to assure the possiblility of Achyranthes japonica Nakai for a cosmetic material. For this we examined the Anti-oxidation, Anti-inflammation, Anti-wrinkle effects of Achyranthes japonica Nakai extract. Each material is extracted from Achyranthes japonica Nakai roots(AJNR) and Achyranthes japonica Nakai stalks(AJNS) using 70% ethanol. We carried out Nitric oxide assay of the extract with cultured RAW 264.7 macrophage cells, And we conducted MMP-1 assay, Type I procollagen synthesis assay of the extract with cultured CCD-986sk fibroblast cells. After we measured ABTS+ assay and SOD assay of AJNR and AJNS, we knew that effect of anti-oxidant increased as their concentration get higher. The result of this study was that the antioxidant activity of AJNR and AJNS was similarly excellent and the anti-inflammatory activity of AJNR was significantly higher than AJNS. The MMP-1 inhibitory activity and Type I procollagen synthesis of AJNR and AJNS was generally excellent, AJNS had slightly better than AJNR. Therefore I thought it has the chance to play an imfortant role as a functional cosmetic material for anti-oxidant, anti-inflammation and wrinkle reduction effects.

This study was carried out to investigate the cathepsin B inhibition effect by Achyranthes japonica N. root extract in vitro. The methanol/$H_{2}O$(4:1, v/v) extract was fractionated by ethyl acetate(F1), chloroform(F2), chloroform/methanol(3:1, v/v)(F3) and methanol(F4). The yield of F4 in Achyranthes japonica N. root was $8.27\%$. As an index material of Achyranthes japonica N. root, 20-hydroxy ecdysone was detected by TLC, and HPLC and it's content was $0.33\%$. Three isolates(F1, F3, F4) showed the cathepsin B inhibition activity, and F4 showed the highest inhibition activity among them. In the inhibition activity on cathepsin B, leupeptin, 20-hydroxy ecdysone and F4(at the same concentration of 20-hydroxy ecdysone.) were 92, 88 and $97\%$ on BANA($N{\alpha}$-benzoyl-DL-arginine ${\beta}$-naphthylamide) substrate, and 62, 36 and $67\%$ on CLN($N{\alpha}$-CBZ(carbobenzlyoxy)-L-lysine p-nitrophenyl ester HCI) substrate, respectively.

In vitro and in vivo experiments using Achyranthis radix and Drynariae rhizoma extracts were conducted. Antioxidant properties were analyzed and the effects on bone, glucose and lipid metabolism were investigated. Drynariae rhizoma (64.67%) obtained higher DPPH radical scavenging activity compared to Achyranthis radix (19.03%). Similar results were obtained in the reducing power. No differences were observed on the ABTS radical scavenging ability and SOD. In contrast, Achyranthis radix (77.60%) has higher chelating ability compared to Drynariae rhizoma (46.21%). In vivo experiments revealed higher plasma TBARS in OVX-DR than in OVX-AR. Opposite result was seen in erythrocyte TBARS. Hepatic, nephritic and erythrocyte enzymes were considered for the antioxidant enzyme activities. GSH-Px and PON of hepatic enzymes were higher in OVX-AR. While the CAT and GR were higher in OVX-DR. SOD, GSH-Px, GR and PON of nephritic enzymes of OVX-DR were higher compared to OVX-AR. Almost similar values were obtained in CAT using both extracts. The OVX treated rats obtained higher CAT and GR in the erythrocyte enzymes compared to SHAM. The SOD of erythrocyte enzymes in OVX-DR was higher compared to OVX-AR. On the other hand, the GSH-Px was higher in OVX-AR.

Acyranthes bidentata has been used as anti-arrthritic, aphrodisiac, anti-viral, anti-spasmodic, anti-hypertensive, anti-coagulant and anti-tumor agent. In this study, we evaluated anti-inflammatory effect of polysaccharide extract from Acyranthes bidentata. Acyranthes bidentata polysaccaride decreased $IL-1{\alpha}$, IL-6, COX-2, and total NO synthesis. Our results point to the potential use of Acyranthes bidentata polysaccaride as a cosmeceutical agent for inflammatory cutaneous symptoms.

Extraction efficiency of ${\beta}-ecdysone$ in Achyranthis radix was investigated using the methods of solvent extraction and supercritical fluid extraction (SFE). The optimum SFE conditions for the analysis of ${\beta}-ecdysone$ in A. radix were 300 atm, $80^{\circ}C$, 100 ml of extraction volume, and 20% ratio of modifier(methanol). As revealed through SFE, detection limit of ${\beta}-ecdysone$ in A. radix was 5 ng and recoveries of ${\beta}-ecdysone$ in A. radix shoots and root were $90.7{\sim}93.5%$ and $77.8{\sim}81.9%$, respectively. Recoveries of ${\beta}-ecdysone$ in A. radix shoots and root through solvent extraction were $76.4{\sim}93.0%$ and $80.6{\sim}93.1%$, respectively. ${\beta}-Ecdysone$ content was determined to be highest at 654.9 ppm in the first year A. radix roots harvested in August.

To screening of antimicrobial activity, 95% ethanol and hot water extracts of roots, fruits, leaves, radix and stems of 50 species of traditional herbal medicines were examined. For their growth inhibitory effects on two food-born microorganisms, S. aureus and E. coli O157:H7, by the paper disc diffusion method and the minimum inhibitory concentration(MIC) test. Moutan radicis Cortex and Achyranthis Radix showed the highest inhibitory activities on both S. aureus and E. coli O157:H7. The Inhibition zones of Moutan radicis Cortex on S. aureus and E. coii O157:H7 were 22 mm and 24 mm respectively, and the corresponding inhibition zone of Achyranthis Radix were 23 mm and 22 mm. The MIC or Achyranthis Radix on S. aureus was 156.25 $\mu$g/mL, and the MIC or Achyranthis Radix and Moutan radicis Cortexas on E. coli O157:H7 were 625 $\mu$g/mL and 312.5 $\mu$g/mL, respectively. Their antimicrobial activities in ethanolic extracts were significantly higher than in hot water extracts. In the various solvent fractions prepared from ethanol extract, the ethyl acetate fraction of Achyranthis Radix and the CHCl$_3$ fraction of Moutan radicis Cortexas showed strongest activity.

In the present work, biochar was prepared using Achyanthes japonica stem as a by-product of herbal medicine. In order to apply the prepared biochar to water treatment process, the adsorption characteristics of zinc and iron ions dissolved in water were investigated. When the experiments were performed for 2 h to remove 70 and 100 mg/L of zinc ions, the adsorption amounts of 32.3 and 31.0 mg/g were obtained, respectively. It was also found that the adsorption amount of Achyanthes japonica stem biochar for the removal process of zinc ion was three times higher than that of the activated carbon. In addition, when the experiments were performed for 2 h to treat 70 and 100 mg/L of iron ions, high adsorption amounts of 50.1 and 54.3 mg/g were achieved, respectively. In order to further enhance the removal efficiency of zinc and iron ions, a steam activation process was performed on the biochar of Achyanthes japonica stem. As a result, the removal efficiencies of 70 and 100 mg/L of zinc ions increased to 80 and 60%, respectively. Also, the removal efficiencies of 70 and 100 mg/L of iron ions were improved to 100 and 82%, respectively. In addition, when the biochar of Achyanthes japonica stem with a steam activation was compared with the untreated biochar of Achyanthes japonica stem, the specific surface area increased 37.3 times, and the total and macroporpous pore volumes were improved by 28.4 and 136 times, respectively. Therefore, the results can be used for economically and practically adsorbing zinc and iron ions contained in water.

In this study, the ethanolic extracts of 40 species of traditional herbal medicines were examined for their antimicrobial activities against Clostridium difficile. Among the 43 screened traditional herbal medicines, Achyranthes Japonica Nakai (AJN), Siegesbeckia glabrescens Makino, and Phelloedendron amurense Ruprecht showed antimicrobial activities greater than 90% at a concentration of 500 ppm. According to the minimum inhibitory concentration (MIC) test the ethyl acetate soluble fraction of the AJN ethanolic extracts (AJNEA) showed the highest growth inhibitory activity against C. difficile, with a MIC of $625{\mu}g/mL$. In addition, the effect of AJNEA on the growth of lactic acid bacteria was investigated. AJNEA did not inhibit the growth of the tested Bifidobacterium spp. or Lactobacillus spp., with the exception of B. longum, Streptococcus thermophilus, and L. helveticus. These results indicate that AJNEA can be utilized as a potential antimicrobial agent against C. difficile related disease.
