Objective : This study was designed to investigate anti-oxidative, anti-aging and anti-inflammatory activities of Zingiber officinale Roscoe water (ZD) and 50% ethanol extracts (ZE). Method : The antioxidant capacity of ZD or ZE was analyzed by DPPH, ABTS scavenging activities and reducing power, respectively. The anti-aging efficacy was performed with tyrosinase and collagenase inhibition activities. The anti-inflammatory activities were confirmed through inhibition of nitric oxide production and TNF-�� expression in LPS-treated Raw 264.7 cells. Result : As a result of measuring DPPH and ABTS radical scavenging activities, both ZD and ZE extracts increased in concentration-dependent manners. The ABTS radical scavenging activities of water and 50% ethanol extract were similar to that of positive control at high concentration. On reducing power, both ZD and ZE showed higher activities than the positive control at high concentration. On inhibition activities of tyrosinase and collagenase both ZD and ZE showed the large inhibition rates at low concentration. Also, the inhibitory efficacy of ZD on NO and TNF-�� production was better than ZE in RAW 264.7 cells. Conclusion : These results suggest that ZD and ZE have anti-oxidative, anti-aging and anti-inflammatory effects in vitro. Especially, ZD was more effective than ZE. Thus, Ginger extract is considered to be highly useful as a cosmetic or food material with anti-oxidative, anti-aging (prevention of whitening and wrinkle) and anti-inflammatory effects. Also these effects may vary depending on the extraction solvent.

BACKGROUND/OBJECTIVES: Schisandrae Fructus, the fruit of Schisandra chinensis Baill., has traditionally been used as a medicinal herb for the treatment of various diseases, and has proven its various pharmacological effects, including anti-inflammatory and antioxidant activities. In this study, we investigated the inhibitory effect of Schisandrae Fructus ethanol extract (SF) on inflammatory and oxidative stress in particulate matter 2.5 (PM2.5)-treated RAW 264.7 macrophages. MATERIALS/METHODS: To investigate the anti-inflammatory and antioxidant effects of SF in PM2.5-stimulated RAW 264.7 cells, the levels of pro-inflammatory mediator such as nitric oxide (NO) and prostaglandin E₂ (PGE₂), cytokines including interleukin (IL)-6 and IL-1β, and reactive oxygen species (ROS) were measured. To elucidate the mechanism underlying the effect of SF, the expression of genes involved in the generation of inflammatory factors was also investigated. We further evaluated the anti-inflammatory and antioxidant efficacy of SF against PM2.5 in the zebrafish model. RESULTS: The results indicated that SF treatment significantly inhibited the PM2.5-induced release of NO and PGE₂, which was associated with decreased inducible NO synthase and cyclooxygenase-2 expression. SF also attenuated the PM2.5-induced expression of IL-6 and IL-1β, reducing their extracellular secretion. Moreover, SF suppressed the PM2.5-mediated translocation of nuclear factor-kappa B (NF-κB) from the cytosol into nuclei and the degradation of inhibitor IκB-α, indicating that SF exhibited anti-inflammatory effects by inhibiting the NF-κB signaling pathway. In addition, SF abolished PM2.5-induced generation of ROS, similar to the pretreatment of a ROS scavenger, but not by an inhibitor of NF-κB activity. Furthermore, SF showed strong protective effects against NO and ROS production in PM2.5-treated zebrafish larvae. CONCLUSIONS: Our findings suggest that SF exerts anti-inflammatory and antioxidant effects against PM2.5 through ROS-dependent down-regulating the NF-κB signaling pathway, and that SF can be a potential functional substance to prevent PM2.5-mediated inflammatory and oxidative damage.

Objectives : This study is to investigate the anti-aging and antioxidant effects of Naesohwangryeon-tang(NSHRT) extract in Hs68 fibroblasts. Methods : The fibroblast cell line Hs68 cells were used and MTT analysis was performed to measure the cell viability of Naesohwangryeon-tang, and then MMP-1 was induced with the cytokine TNF-𝛼 to confirm the anti-aging effect through real-time PCR and ELISA. In addition, ROS was induced with the TNF-𝛼 to confirm the anti-oxidant effect through DCF-DA. The signaling pathway according to the antioxidant effect was performed by western blot. Results : Naesohwangryeon-tang did not show cytotoxicity at all concentrations(100-800㎍/㎖) treated on Hs68 cells, and the inhibitory effect of MMP-1 was also confirmed. In addition, it was confirmed that the intracellular ROS increased by TNF-α was decreased by Naesohwangryeon-tang, and it was confirmed that the expression of NQO1 was increased in a concentration-dependent manner of Naesohwangryeon-tang. Conclusions : These results suggest that Naesohwangryeon-tang can be used as an anti-aging material by demonstrating the anti-aging and antioxidant effects of Naesohwangryeon-tang.

To investigate the effect of ethanol extract of Saxifraga stolonifera MEERBURGH on skin care, we measured anti-oxidant and anti-aging activity. S. stolonifera ethanol extract itself had anti-oxidant activity in a dose-dependent manner in DPPH radical scavenging. Silica dose-dependently increased the intracellular ROS generation in RAW 264.7 cells. S. stolonifera ethanol extract inhibited silica-induced intracellular superoxide anion generation, $H_2O_2$ and hydroperoxide generation in RAW 264.7 cells. S. stolonifera ethanol extract significantly inhibited both hyaluronidase and elastase activity, also significantly inhibited MMP-1(collagenase) activity as well. In NIH 3T3 fibroblast cells, S. stolonifera ethanol extract significantly increased collagen-like polymer synthesis, which suggesting the S. stolonifera ethanol extract might be used as hydration and anti-wrinkle agents. From the above results, it is suggested that the main ingredients of S. stolonifera ethanol extract play an important role in anti-oxidant and anti-aging activity.

Ganjang and doenjang are known as major fermented soy-based foods in Koreans. Current investigations have proved that fermented soybean foods impart anti-cancer, anti-obesity, and anti-diabetic effects. The aim of this study was to evaluate the anti-cancer activities of commercialized soy food, Ganjang, as a function of aging period. The test groups were classified into four time periods-short (under 5 years, S group), mid (under 10 years, M group), long (under 15 years, L group), and eternal (over 15 years, E group). The anti-cancer effects of Ganjang were determined by cell cytotoxicity assay of three types of cancer cell lines and splenocyte proliferation assay. Besides these assays, we also analyzed NK cell activity for cancer immunotherapy. The results show that the anti-cancer effect increased in the S and M period aging groups for all three cancer cell lines. Interestingly, similar to the anti-cancer result, splenocyte proliferation and NK activity showed the highest effect in the S and M groups. In contrast, Japanese ganjang-treated (JG1, JG2) groups and E group showed significantly reduced splenocyte proliferation. Collectively, these results suggest that the short and middle periods of traditional fermented Ganjang might have potential anti-cancer activities.
