In this study, the antioxidant effect and component analysis for extract and fractions of Cardiospermum halicacabum leaf were investigated. All experiments were performed with 50% ethanol extract, ethyl acetate fraction and aglycone fraction obtained from dried C. halicacabum leaf. The yields of extract and fractions were 16.4, 0.9 and 0.3% per dried powder, respectively. DPPH (1,1-phenyl-2-picrylhydrazyl) radical scavenging activity ($FSC_{50}$) of ethyl acetate fraction ($92.5{\mu}g/mL$) was the greatest radical scavenging activity, but lower than (+)-${\alpha}$-tocopherol ($8.9{\mu}g/mL$). In reactive oxygen species (ROS) scavenging activity (total antioxidant capacity, $OSC_{50}$) on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system, aglycone fraction ($4.2{\mu}g/mL$) was the highest total antioxidant capacity and similar to L-ascorbic acid ($1.5{\mu}g/mL$). The cellular protective effects of C. halicacabum leaf extract and fractions on the $^1O_2$-induced cellular damage of human erythrocytes were exhibited at all concentration-dependent ($5.0-25.0{\mu}g/mL$). Especially, aglycone fraction (${\tau}_{50}$, 76.4 min) in $25.0{\mu}g/mL$ showed the most protective effect among extracts. Components of the ethyl acetate fraction obtained from C. halicacabum extracts were analyzed by TLC, HPLC chromatogram and LC/ESI-MS. Results showed that the ethyl acetate fraction contained some flavonoids, such as apigenin-7-O-glucuronide, apigenin-7-glucosdie and quercitrin hydrate. These results suggest that the extracts and fractions of C. halicacabum leaf may be applied as antioxidant functional cosmetic raw materials.

The antioxidant and anti-inflammatory effects of Corni fructus extracts (CEF, EtOAc extraction; CBF, buthanol extraction; CWF, water extraction) were investigated. The total phenolics of CEF (173.3 mg TAE/g) were significantly higher than those of CWF (26.7 mg TAE/g) and CBF (94.8 mg TAE/g). DPPH and ABTS free radical scavenging activity of CEF (DPPH: $RH_{50}$; $25.1{\mu}g/mL$, ABTS: $RC_{50}$; $36.1{\mu}g/mL$) showed even higher than that of BHA and ${\alpha}-tocopherol$ used as positive control. All three Corni fructus extracts in the concentration of $1{\sim}100{\mu}g/mL$ were effective inhibitors of NO and prostaglandin $E_2$ ($PGE_2$). NO production was inhibited 71.3~92.2% by CEF, 76.8~85.5% by CBF and 74.4~96.9% by CWF, respectively. CEF, CBF and CWF ($1{\sim}100{\mu}g/mL$) inhibited also pro-inflammatory cytokines like $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 very effectively. $TNF-{\alpha}$ was inhibited up to 51.2% by CWF and $IL-1{\beta}$ was inhibited up to 67.1% by CEF. IL-6 was best inhibited by CEF up to 58.9%. This study suggested the potential of Corni fructus for use as an excellent antioxidant substance and inflammatory inhibiting mediators. Therefore CEF, CBF and CWF Corni fructus extracts may be used for therapeutic approach to various inflammatory diseases.

In this study, the antioxidative effects of Aronia melanocarpa fruit and leaf extracts were investigated. The free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activities ($FSC_{50}$) of the ethylacetate and aglycone fractions of fruit extracts were 16.29 ${\mu}g/mL$, and 12.29 ${\mu}g/mL$, respectively. The free radical scavenging activity of fruit extract was higher than that of leaf extracts. Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of the ethylacetate and aglycone fractions of fruit extracts on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system using the luminol-dependent chemiluminescence assay showed 2.86 ${\mu}g/mL$, and 1.80 ${\mu}g/mL$, respectively. ROS scavenging activity of the aglycone fraction of fruit extracts was similar to that of L-ascorbic acid (1.50 ${\mu}g/mL$). The ROS scavenging activity of fruit extracts was higher than that of leaf extracts. The cellular protective effects of aglycone fraction of fruit extracts (${\tau}_{50}$ = 72.3 min) on the $^1O_2$-induced cellular damage of human erythrocytes especially were increased in a concentration dependent manner (5 ~ 50 ${\mu}g/mL$). ${\tau}_{50}$ (72.3 min) of the aglycone fraction showed 1.9 times higher than (+)-${\alpha}$-tocopherol (38 min), known as lipophilic antioxidant at 10 ${\mu}g/mL$. These results incidicate that A. melanocarpa fruit extracts have higher antioxidant effects than leaf extracts and could be applicable to functional cosmetics materials for antioxidants by protecting skin exposed to solar UV radiation against ROS including $^1O_2$.

In this work, licorice extracts were prepared using various extraction conditions such as extraction solvent, temperature, and time from Glycyrrhiza uralensis (G. uralensis) produced in Korea and China and Glycyrrhiza glabra (G. glabra) in Uzbekistan. The optimum extraction condition was selected from the extraction yields and antioxidative activities of extracts. Korea licorice extracts showed the highest free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity (46.05%) under the extraction condition of 85% ethanol at $60^{\circ}C$ for 6 hours. The prominent ROS (reactive oxygen species) scavenging activity using luminol-dependent chemiluminescence assay and the cellular protective effect against $^1O_2$ induced cellular membrane damage were also shown from the extracts obtained from the same condition. Especially, Korea G. uralensis extracts exhibited the higher prominent protective effect (${\tau}_{50}$ = 116.4 min) than (+)-(+)-${\alpha}$-tocopherol (${\tau}_{50}$ = 28.5 min) and the extraction yield of Korea licorice extract was 18.75%, which is 1.2 times and 2.5 times higher than that of Uzbekistan and China, respectively. These results indicate that the extraction condition of 85% ethanol at $60^{\circ}C$ for 6 hours is optimal to prepare licorice extracts, which can be applicable as anti-oxidative cosmetic materials.

In this study, the antioxidant effect of Chungkukjang supplementation against memory impairment and oxidative stress in scopolamine (2 mg/kg i.p)-injected mice was investigated. The experimental animals were divided into five groups and fed experimental diets for 12 weeks; normal diet group (C), scopolamine + normal diet group (S), scopolamine + 63.0% soybean Chungkukjang supplementation group (SS), scopolamine + 45.0% Yakkong Chungkukjang supplementation group (SY), and scopolamine + 50.0% black foods such as black rice, black sesame seeds, and sea tangle added Yakkong Chungkukjang group (SYB). For the results of food intake, body weight gain, and brain weights, levels of scopolamine-injected groups were lower than the levels of the control group. The reduced brain weight of the scopolamine-injected group (S) was regulated to control level by supplementation of three types Chungkukjang. In the oxidative stress indicator, nitric oxide and malondialdehyde levels in serum of scopolamine-injected mice were higher than those of other groups. However, supplementation of soybeans, Yakkong and black foods added Yakkong Chungkukjang was proven to regulate them. Antioxidant enzyme activities such as superoxide dismutase (SOD) and glutathione-S-transferase (GST) in serum showed no significant differences among the groups. The reduced levels of vitamin A and vitamin E in serum and brain tissue of scopolamine-injected mice were controlled by supplementation of three types of Chungkukjang. Total antioxidant capacity (TAC) of scopolamine-injected group was lower than those of other groups. However, TAC was significantly elevated by Chunggukjang supplementation. Therefore, antioxidative effects of soybeans, Yakkong, and black foods added Yakkong Chungkukjang supplementations against oxidative stress in scopolamine-injected in mice could expected.
