  • 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.

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.
