Objectives: In this study, we investigated physicochemical characteristics and antioxidant activity of Artemisia argyi H. fermented with lactic acid bacteria. Methods: The A. argyi water extract was fermented using lactic acid bacteria isolated from kimchi at 30℃ for 96 h. To evaluate the physicochemical characteristics, we investigated pH, total acidity, viable cells, free sugars, free organic acids, and free amino acids contents during fermentation. In addition, we examined antioxidant activity of fermented Artemisia argyi H. by measurement of 2,2-diphenyl-1-(2,4,6-trinitrophenyl)-hydrazinyl (DPPH) and 2,2'-azubi-bus-3-ethylbenzothiazoline-6-sulfonic acid (ABTS⁺) scavenging activities. Results: During fermentation time, pH of fermented A. argyi was decreased from 4.57 to 3.22, and total acidity was increased from 0.39% to 1.63%. The number of lactic acid bacteria fermented A. argyi was increased from 1.28×10⁷ CFU/ml to 3.75×10⁸ CFU/ml during fermentation time. The free sugars of fermented A. argyi were confirmed glucose and sucrose. In addition, the organic acid content of fermented A. argyi was the highest in oxalic acid and lactic acid. In the composition of free amino acids, content of ornithine increased from 4.4 mg/100 g to 18.8 mg/100 g compared with non-fermented A. argyi. Furthermore, DPPH and ABTS⁺ radical scavenging activities of fermented A. argyi increased in a dose-dependent manner. Conclusions: In conclusion, our data suggest that lactic acid fermentation of A. argyi could be used as a functional food for antioxidants.

Objectives This study is carried out to investigate the effects of Lonicera japonica in wound-induced rats. Methods Rats were divided into 5 groups; normal (Nor), control (Veh), positive comparison (PC), Lonicera japonica 100 mg/kg (LL), Lonicera japonica 200 mg/kg (LH), each n=8. Total polyphenol and flavonoid were quantified. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3 ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radical scavenging activation were measured. Reactive oxygen species (ROS) was measured in serum. Antioxidant factors and inflammatory factors were measured in skin tissue, and also hydroxyproline content. Skin tissue was analyzed by Hematoxylin & Eosin and Masson's trichrome staining method. Results Total polyphenol and flavonoid were 32.86±0.14 mg/g and 67.17±0.57 mg/g. The IC₅₀ values of DPPH and ABTS free radical scavenging activation were 26.69±1.50 ㎍/mL and 49.33±4.52 ㎍/mL. ROS was significantly lower in LL and LH groups. Nuclear factor-erythroid 2-related factor 2 (Nrf2) was significantly higher in LH group and higher in LL group but not significant. Superoxide dismutase 1 (SOD-1), catalase, and heme oxygenase 1 (HO-1) were significantly higher in LL and LH groups. Nuclear factor kappa-B p65 (NF-κBp65), phosphorylated iκBα (p-iκBα), cyclooxygenase 2 (COX-2), and tumor necrosis factor alpha (TNF-α) were significantly lower in LL and LH groups. Hydroxyproline was significantly higher in LL and LH groups. The histopathologic analysis showed that skin tissue had recovered further more in LL and LH groups than in Veh group.

Objective : The purpose of this study was to establish the simultaneous analysis for six compounds in Gumiganghwal-tang (GMGHT, Jiuweiqianghuo-tang) and to investigate the anti-atherosclerotic effects of GMGHT in vitro. Methods : The column for separation of six compounds was used Luna $C_{18}$ column and maintained at $40^{\circ}C$. The mobile phase for gradient elution consisted of two solvent systems, 1.0% acetic acid in water and 1.0% acetic acid in acetonitrile. The analysis was carried out at a flow rate of 1.0 mL/min with pothodiode array (PDA) detection at 254, 280, and 320 nm. The injection volume was 10 ${\mu}L$. The antioxidant activities of GMGHT were evaluated by measuring free radical scavenging activities on 2,2'-Azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) and 1-1-diphenyl-2-picrylhydrazyl (DPPH). The inhibitory effects on low-density lipoprotein (LDL) oxidation were evaluated by the formation of thiobarbituric acid relative substances (TBARS), relative electrophoretic mobility (REM), and fragmentation of apolipoprotein B (ApoB)-100. Results : Calibration curves were acquired with $r^2{\geq}0.9998$. The contents of liquiritin, ferulic acid, baicalin, baicalein, glycyrrhizin, and wogonin in GMGHT were 1.784, 1.693, 37.899, 0.258, 1.869, and 0.034 mg/g, respectively. The GMGHT showed the radical scavenging activity in a dose-dependent manner. The concentration required for 50% reduction ($RC_{50}$) against ABTS and DPPH radicals were 72.51 ${\mu}g/mL$ and 128.49 ${\mu}g/mL$. Furthermore, GMGHT reduced the oxidation properties of LDL induced by $CuSO_4$. Conclusion : HPLC-PDA is considered as an available and convenient method for quality control and standardization of GMGH and GMGHT has potentials on anti-atherosclerosis by anti-oxidative effect and suppressive effect on LDL oxidation.

본 연구는 열수와 에탄올 용매에 따른 복령 및 산수유 추출물의 농도별로 항산화 활성, 항염증 효과 및 신경세포 보호효과에 미치는 영향을 살펴보고자 진행하였다. 추출물들의 총 polyphenol 함량은 복령 열수 추출물에서 가장 높았고, 복령 에탄올 추출물, 산수유 열수 추출물, 산수유 에탄올 추출물 순으로 유의적으로 감소되는 경향을 나타냈다. DPPH 및 ABTS radical 소거 활성능은 추출물의 농도 의존적으로 증가하였고 산수유 열수 추출물은 모든 추출물에서 항산화 활성이 가장 높게 나타났으며, 복령 열수 추출물은 에탄올 추출물에 비해 높은 활성이 확인되었다. 복령과 산수유에 함유된 총 polyphenol과 항산화 성분을 추출하기 위해서는 에탄올 추출방법 보다는 열수 추출방법이 효과적인 방법이라고 사료된다. LPS로 염증이 유도된 RAW 264.7 세포에서 복령추출물이 산수유 추출물에 비해 NO 생성 억제 효과가 우수한 것으로 확인되었다. MPP⁺에 의해 유도된 SH-SY5Y 신경세포에 복령 열수 추출물은 산수유 열수 추출물에 비해 산화적 스트레스로부터 신경세포 보호효과가 우수하게 나타났다. 복령과 산수유 추출방법에 따른 항산화, 항염 및 산화적 스트레스로부터의 신경세포 보호효과를 갖는 기능성 소재로서 가능성이 있다고 사료된다.
