This study focused on the anti-oxidative and collagenase- and elastase inhibition effects of low molecular weight peptides (LMP) from commercial Jeju horse leg bone hydrolysates (JHLB) on pancreatin, via enzymatic hydrolysis. Cell viability of dermal fibroblasts exposed to UVB radiation upon treatment with LMP from JHLB was evaluated. Determination of the antioxidant activity of various concentrations of LMP from JHLB were carried out by assessing 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2-azino-bis-3-ethybenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activity, ferric reducing antioxidant power (FRAP), and oxygen radical absorbance capacity (ORAC). The DPPH radical scavenging activity of LMP from JHLB (20 mg/mL) was 92.21% and ABTS radical scavenging activity (15 mg/mL) was 99.50%. FRAP activity (30 mg/mL) was $364.72{\mu}M/TE$ and ORAC activity (1 mg/mL) was $101.85{\mu}M/TE$. The anti-wrinkle potential was assessed by evaluating the elastase- and collagenase inhibition potential of these LMP. We found that 200 mg/mL of LMP from JHLB inhibited elastase activity by 41.32%, and 100 mg/mL of LMP from JHLB inhibited collagenase activity by 91.32%. The cell viability of untreated HS68 human dermal fibroblasts was 45% when exposed to a UVB radiation dose of $100mJ/cm^2$. After 24 h of incubation with $500{\mu}g/mL$ LMP from JHLB, the cell viability increased to 60%. These results indicate that LMP from JHLB has potential utility as an anti-oxidant and anti-wrinkle agent in the food and cosmetic industry. Additional in vivo tests should be carried out to further characterize these potential benefits.

The purpose of this study was to investigate the antioxidant, anti-inflammatory and anti-cellular adhesion molecules effects of Allii Macrostemonis Bulbus, Artemisiae Capillaris Herba, Curcumae Radix, Crataegi Fructus, Salviae Militiorrhizae Radix complex extract(AMCP) on the inhibition of atherosclerosis in HUVEC. We measured DPPH radical scavenging activity and ABTS radical scavenging activity of AMCP to evaluate its antioxidant effect. And we also measured the expression level of NF-κB, IκBα, ERK, JNK, p38 proteins to evaluate its anti-inflammatory effect. Lastly, we measured the expression level of MCP-1, ICAM-1, VCAM-1 mRNA and their level to evaluate its anti-celluar adhesion molecules. AMCP did not show any cytotoxicity in HUVEC within the concentraion tested except for a concentration of 400 ㎍/㎖. AMCP increased the DPPH radical scavenging activitiy and ABTS radical scavenging activity in HUVEC as the concentration of AMCP rises. AMCP significantly reduced NF-κB, IκBα, JNK, ERK and p38 protein expression in HUVEC compared to control group. AMCP significantly reduced MCP-1, ICAM-1, VCAM-1 gene expresion in HUVEC compared to control group. AMCP significantly decreased the levels of MCP-1, ICAM-1, VCAM-1 in HUVEC compared to control group. These results suggest that AMCP has effects on antioxidation, anti-inflammation and anti-cellular adhesion molecule, which helps the treatment and prevention of dyslipidemia and atherosclerosis.

Eucommiae Cortex was extracted in distilled water at $100^{\circ}C$ for 3 hours, and filtered. filtered. Extract samples were freeze-dried at $-80^{\circ}C$. Comparison of anti-oxidant activity in Eucommiae Cortex samples from regional groups was measured in 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) free radical scavenging, and ferric reducing antioxidant power (FRAP) between regional groups of Eucommiae Cortex. In addition, high-performance liquid chromatography (HPLC) analysis was conducted to compare pinoresinol diglucoside concentration by regional groups. Results : HPLC analysis found that pinoresinol diglucoside concentration, widely known as the marker compound of Eucommiae Cortex, was the highest in Gangwon Yeongwol. There was a significant difference in anti-oxidative activity of Eucommiae Cortex between regional groups as discovered in DPPH, ABTS and FRAP assays. DPPH free radical scavenging was the highest in Jeonbuk Jangsu. ABTS free radical scavenging was the highest in Jeonbuk Jangsu and Chungbuck Jecheon. FRAP was the highest in Jeonbuk Jangsu. Conclusions : Although pinoresinol diglucoside concentration was high, anti-oxidative activity was not proportionately high. Pinoresinol diglucoside concentration was the highest in Gangwon Yeongwol. Anti-oxidative activity was the highest in Jeonbuk Jangsu.

The objective of this study was to investigate the antioxidant and anti-inflammatory activities of Eugenia caryophyllata Thunb. water and 70% ethanol extracts. The content of total polyphenol was significantly higher in water extract than in 70% ethanol extract. The DPPH radical scavenging activity of water extract was similar to that of Vit. C at a concentration of $1,000{\mu}g/mL$. The ABTS radical scavenging activities of water and 70% ethanol extract were similar to that of Vit. C at a concentration of $1,000{\mu}g/mL$. SOD-like activity of water extract was higher than that of 70% ethanol extract at a concentration of $1,000{\mu}g/mL$ but lower than that of Vit. C. The DPPH radical scavenging activity, ABTS radical scavenging activity, and SOD-like activity increased as concentrations of water and 70% ethanol extracts increased. Cell cytotoxicity was not observed at all concentrations except at $100{\mu}g/mL$ concentration of water extract. Inhibitory activity on NO production effect of water extract was significantly higher than that of 70% ethanol extract. These results show that E. caryophyllata Thunb. has potent biological activities, and their activities were different depending on extraction solvent.

This research old age chestnut tree that loss function chestnut leaf renewal efficiency enlargement and development of cosmeceutical product by purpose. Chestnut leaf (CL) exhibits numerous pharmacological effect including anti-allergy and anti-microbial properties. However, the anti-wrinkle effect of CL is not completely understood. In this study, to find a possible explanation for the anti-wrinkle effects of CL, we evaluated the effects of CL on radical scavenging activity, elastase inhibition activity and collagenase inhibition activity. CL was extracted with various solvents including water (CLW), 70% ethanol (CLE) and 70% acetone (CLA). The results showed that CLW, CLE, and CLA have the radical scavenging activity. In addition, we showed that CLW, CLE, and CLA have the elastase inhibition activity and collagenase inhibition activity. Consequently, the CL has a potent anti-wrinkle effect and it could be a useful cosmeceutical product for anti-aging purposes.

Objectives： Polygonati Rhizoma (PR) has containing the bioactive compounds such as poly sccharide A,B,C, oligosaccharide, amino acid, it has reported to anti-diabetes and hypertension, atherosclerosis. In this study, we were evaluates antioxidant and anti-physical fatigue effects of PR and steamed PR.Methods : The sample was divided into 5 groups-PR0 (PR without steaming process), PR1 (PR with once steaming process), PR3 (PR with third steaming process), PR6 (PR with sixth steaming process), PR9 (PR with ninth steaming process). We measured anti-oxidant activity through contents of polyphenol, flavonoid and DPPH, ABTS free radical scavenging capacity. And, anti-physical fatigue effect was evaluated using the swimming test, and the AMPK protein expressions in soleus muscle.Results ： As a result, polyphenol, flavonoid, DPPH, ABTS free radical scavenging capacity of PR were increased as steaming times. Anti-physical fatigue effects by swimming test, PR0 have significantly increased, but steamed PR groups were decreased. The AMPK protein expressions of PR0 and PR1 groups were increased comparing with PR3, PR6 and PR9. All groups had effects on decreasing TG, creatine in blood serum, but had no effects on TC in blood serum.Conclusions ： In conclusion, PR with 9 steaming process was more excellent than not-processed PR in anti-oxidant effect such as DPPH, ABTS radical scavenging activity and contents of polyphenol, flavonoid, but, not-processed PR increased swimming times than processed PR. These results suggest that processed PR has anti-oxidant effect as steaming times, and not-processed PR may be a novel potential anti-physical fatigue agents than processed PR.
