Having idea to develop more effective anti-diabetic agent from ginseng root, we comprehensively assessed the anti-diabetic activity and mechanisms of ginsam in C57BL/KsJ db/db mice. The db/db mice were divided into 4 groups; diabetic control (DC), ginsam at a dose of 300 or 500 mg/kg (GS300 or GS500) and metformin at a dose of 300 mg/kg (MT300). Ginsam was orally administered for 8 weeks. GS500 reduced the blood glucose concentration and significantly decreased an insulin resistance index. In addition, GS500 reduced the plasma non-esterified fatty acid, triglyceride, and increased high density lipoprotein-cholesterol as well as decreased the hepatic cholesterol and triglyceride. More interestingly, ginsam increased the plasma adiponectin level by 17% compared to diabetic control group. Microarray, quantitative-polymerase chain reaction and enzyme activity results showed that gene and protein expressions associated with glycolysis, gluconeogenesis, and fatty acid oxidation were changed to the way of reducing hepatic glucose production, insulin resistance and enhancing fatty acid $\beta$-oxidation. Ginsam also increased the phosphorylation of AMP-activated protein kinase and glucose transporter expressions in the liver and skeletal muscle, respectively. These changes in gene expression were considered to be the mechanism by which the ginsam exerted the anti-diabetic and anti-dyslipidemic activities in C57BL/KsJ db/db mice.

In vitro anti-obesity effects of anti-cancer (AC) functional kimchi in differentiated 3T3-L1 adipocytes were studied. We constructed three experimental groups: Control, standardized kimchi (SK), and AC functional kimchi (A-FK) that included active ingredients and Lactobacillus plantarum. Kimchi extracts did not show any cytotoxicity in pre-adipocytes in the concentration range of 1 - 5 mg/mL. A-FK significantly reduced fat droplet formation and absorbance in differentiated 3T3-L1 adipocytes, as shown by Oil red O staining, compared to Control and SK (P < 0.05). SK and A-FK reduced adipo-/lipogenesis related genes such as $C/EBP{\alpha}$, SREBP-1, LPL, and $LXR{\alpha}$ compared to Control (P < 0.05). Especially, A-FK more greatly reduced SREBP-1 and LPL compared to SK (P < 0.05). A-FK up-regulated the ${\beta}$-oxidation related gene CPT-1c and down-regulated the pro-inflammatory cytokine IL-6 compared to Control (P < 0.05). Based on the results, A-FK exhibited anti-obesity effects by inhibiting fat droplet formation and adipo-/lipogenesis related genes by regulating the ${\beta}$-oxidation related gene CPT-1c and pro-inflammatory cytokine IL-6. In previous studies, A-FK kimchi already exhibited a strong anti-cancer effect. These results indicate that A-FK increased anti-obesity activity in this model system due to its functional ingredients and anti-cancer functionality.

Objectives : This study was an analysis of the anti-inflammatory, anti-oxidative and skin whitening properties of Gamioncheong-decoctione(GMOCD) extract. Methods : GMOCD(96 g) and 2 L of distilled water were heated at $100^{\circ}C$ for four hours and then concentrated, frozen, freeze-dried, dissolved in distilled water and filtered. The following analysis was completed: cell cytotoxic effect using MTT assay, oxidative products of NO by griess assay, concentration of prostaglandin $E_2(PGE_2)$ by commercially competitive enzyme immunoassay, and cytokines($IL-1{\beta}$, IL-6 and TNF-${\alpha}$) by Bio-Plex$^{(R)}$ Suspension Array System's Bio-Plex Pro$^{TM}$ mouse cytokine, chemokine, and growth factor assay. Anti-oxidative effect was measured using the DPPH method and skin whitening effect using tyrosinase inhibition assay. Results : GMOCD water-extract did not show any toxicity at all doses and cell viability was more than 90 % at all doses. GMOCD water-extract significantly inhibited NO production at doses of 100, 200, $400{\mu}g/ml$, significantly inhibited $PGE_2$ production at doses of 200 and $400{\mu}g/ml$ and reduced the LPS-induced IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ production in a dose-dependent manner. $IL-1{\beta}$ production was significantly reduced at a dose of $400{\mu}g/ml$ and IL-6 production was significantly reduced at doses of 200 and $400{\mu}g/ml$. DPPH free radical scavenging capability had a skin whitening effect rate of more than 50%. Tyrosinase inhibition activity was apparent in a dose-dependent manner. Conclusions : This study suggests that GMOCD water-extract suppressed NO and $PGE_2$ production and inhibited cytokines($IL-1{\beta}$, IL-6 and TNF-${\alpha}$). GMOCD also improved DPPH free radical scavenging capability. GMOCD water-extract increased tyrosinase inhibitory activity in a dose-dependent manner but this was not a statistically significant result.

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.

In this study, extracts from Caryopteris incana Miq. (C. incana) were investigated to assess anti-oxidation, skin-whitening and anti-wrinkle activity. The total phenolic compounds of C. incana extracts with water and 80 % ethanol showed 7.69 and 12.50 mg/g respectively. Antioxidation activity of C. incana extracts was measured by using 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), protection factor (PF), and Thiobarbituric acid reactive substances (TBARs). At concentration of $200{\mu}g/mL$, the DPPH free radical scavenging activity of water and ethanol extracts were 84 and 92 %, respectively. ABTS radical scavenging activity of water and ethanol extracts were both at approximately 99 %. Antioxidant PF of water and ethanol extracts were 1.56 PF and 1.67 PF, respectively. The TBARs of water and ethanol extracts were 62 and 82 %, respectively. In anti-wrinkle and skin-whitening activity, 80 % ethanol extract had more outstanding effect than water extract at concentration of $200{\mu}g/mL$. The levels of elastase and collagenase inhibitory activity related with anti-wrinkle were 58 and 89 % in ethanol extract. The tyrosinase inhibitory activity related with skin-whitening was 13 % in ethanol extract. The astringent effect of ethanol extract was 50 %. Throughout the results, C. incana extracts showed an excellent effect on anti-oxidation, skin-whitening and anti-wrinkle activity. Therefore, C. incana extracts can be used as a new material for cosmetics.

The current study was performed to investigate the changes of bio-activities of Salicornia europaea (SE) depending on the different dry methods. The ethanol extracts were prepared from the freeze-drying SE (FD), hot-air drying SE (HD), and shade drying SE (SD). Their anti-oxidant and anti-thrombosis activities were compared. The yields of ethanol extraction in FD, HD, and SD were 14.4, 13.2 and 11.9%, respectively. The highest contents of total polyphenol (4.6 mg/g) and total sugar (23.4 mg/g) were shown in FD, whereas, the highest content of reducing sugar (14.6 mg/g) was observed in HD. In anti-oxidation activity assay, the FD and HD showed similar radical scavenging activities and reducing power. However, in SD, nitrite scavenging activity and reducing power were severely decreased. In anti-coagulation activity assay, the thrombin time (TT), prothrombin time (PT) and activated partial thromboplastin time (aPTT) of FD, HD and SD did not show significant changes at 5 mg/mL concentration. But the HD at 7 mg/mL had strong inhibitions against thrombin and blood coagulation factors. The platelet aggregation and hemolysis activities were not affected by dry methods. Our results suggest that both FD and HD are effective to maintain the functional ingredient of SE, and HD is economic and efficient dry process for production of functional food.

Background: Glycyrrhiza radix (licorice root) have been used as an oriental medicine material for long time, and its protective effects on oxidative stress, inflammation and cognition deficit have been recently reported. However, the cultivation of Glycyrrhiza species as medicinal crops is associated with some problems such as low productivity and early leaf fall, etc. To resolve this problems, Glycyrrhiza cultivars have been developed by direct hybridization of each Glycyrrhiza species by Korean researchers. The present study was conducted to compare the Glycyrrhiza cultivar radix (Dagam, Sinwongam and Wongam) for their anti-oxidation, anti-inflammation, and cognition improvement effects and levels of liquiritin, isoliquiritigenin and licochalcone in order to select an excellent cultivar as a material resource. Methods and Results: For evaluating the inhibitory efficacies of the Glycyrrhiza cultivar extracts on oxidative stress and inflammation in BV2 cells, we measured their reactive oxygen species (ROS) production and nitric oxide (NO) release after treating them with lipopolysccharide. The scavenging activities on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and peroxynitrite ($NOO^-$) radicals were evaluated. Cell proliferation and N-methyl-D-aspartate receptor (NMDAR) inhibition were analyzed. The total phenol, liquiritin, isoliquiritigenin and licochalcone A content in the extracts of the three culivars were quantified. Furthermore, the correlation coefficient between the activities and contents of total phenol, liquiritin, isoliquiritigenin and licochalcone A were also calculated. The results indicated that Sinwongam exhibited potent anti-oxidant, anti-inflammatory and NMDAR inhibititory activities. Sinwongam also showed higher total phenol and licochalcone A contents than the other cultivars. Among the three cultivars, Dagam exhibited a positive effects on NO release inhibition, cell proliferation and contents of liquiritin and isoliquiritigenin. Conclusions: Sinwongam is expected to be the most useful resource as a functional material for anti-oxidation/anti-inflammation and cognition improvement among the three studied licorice cultivars.

Objectives We evaluated the improving effects of Taeksa-tang (TST) using 3T3-L1 cells and C57BL/6 mice were fed on a high-fat diet. Methods The anti-radical activities of TST were studied using 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid). The content of total polyphenol was measured using Folin-Ciocalteu reagent, whereas aluminum chloride colorimetric method was used for the content of total flavonoid. Moreover, the factors related to lipid profile and the protein expressions such as 𝛽-oxidation and anti-oxidant enzyme were analyzed using serum and western blotting of 3T3-L1 cells. Additionally, we examined lipolysis through glycerol appearance in mouse adipose tissue. Results TST treatment showed strong free radical scavenging activities with half maximal inhibitory concentration and the presence of a amount of total polyphenol and total flavonoid. TST treatment significantly increased factors related to 𝛽-oxidation such as carnitine palmitoyl transferase-1 and uncoupling protein 2 via the phosphorlyation of liver kinase B1 (LKB1) and AMP-activated protein kinase (AMPK). Moreover, the protein expressions of anti-oxidant enzyme and lipolysis were significantly elevated by TST administration. In addition, TST supplementation lowered serum malondialdehyde, triglyceride, and total cholesterol levels compared with the control group. Taken together, these data suggest that TST treatment regulated lipid parameters via the increase of 𝛽-oxidation by LKB1-AMPK signaling pathway. Conclusions TST may have a potential remedy in the prevention and treatment of obesity. Therefore, this study may provide the scientific basis for TST use.
