Oxidative rancidity in foods causes undesirable changes in nutritive value, aroma, flavor, and color. Salix Koreensis Andersson in DC. (SK) has anti-oxidative and anti-inflammatory effects and is traditionally used to treat neuralgia, edema, pain, and inflammatory diseases. However, the regulatory effects of SK on oxidative and inflammatory reactions have not been elucidated. In this context, we scientifically validated the anti-oxidative and anti-inflammatory activities of SK leaf (SKL). The methanol extract of SKL was evaluated for in vitro anti-oxidative activities. SKL showed increased superoxide dismutase (SOD)-like activity and 1, 1-diphenyl-2-picrylhydrazyl radical scavenging activity. The in vitro anti-oxidant and anti-inflammatory activities of SKL were also investigated in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. LPS resulted in decreased SOD activities compared with the unstimulated cells, but SKL significantly increased SOD activities reduced by LPS. In addition, LPS-induced nitric oxide, tumor necrosis factor-${\alpha}$, and interleukin-6 productions were significantly and dose-dependently reduced by SKL in RAW264.7 macrophages without inducing cytotoxicity. In conclusion, these results indicate that SKL will be able to be effectively used as a food additive with anti-oxidative and anti-inflammatory effects.

Ten 1,2,4-thiadiazolidines were synthesized and screened for their anti-inflammatory and analgesic activities. Butyl isothiocyanate was used as a starting material. Several compounds showed significant anti-inflammatory and analgesic activities. The unsubstituted and o-methyl, p-acetoxy and o-chloro substituted compounds were found to be more potent anti-inflammatory and analgesic agents than the other compounds.

The present study aims to detect the rare flavonoids isolated from the leaves of Persicaria glabra. The known flavonoids: quercetin (1), isorhamnetin (2), avicularin (3) and new one isorhamnetin-3-O-α-L-(6''-E-p-coumaroyl)-rhamnoside (4) were identified by HPLC, UV, IR and NMR. P. glabra has used traditionally for its analgesic, anti-inflammatory and anti-rheumatic properties. To find out the ingredients responsible for the efficiency of this plant, we have used to study the anti-microbial and anti-inflammatory activities of different extracts.

In the present study Momordica dioica fruit pulp was successively extracted with hexane and methanol. To the concentrated methanolic extract ethyl acetate was added and ethyl acetate soluble portion was separated. Both hexane extract (HE) and ethyl acetate soluble portion (EASP) of methanolic extract was vacuum dried to yield the respective HE and EASP. HE and EASP were evaluated for its analgesic and anti-inflammatory activities in a dose of 50 and 100 mg/kg in mice and rats. Both HE and EASP significant exhibited analgesic and anti-inflammatory activities when compare to standard drug.

The aim of the study was to determine the anti-inflammatory activities of the plants with origin of China. The Fissistigma poilanei, which is a species of plant in the family Annonaceae and Rubus laxus Focke, which is a species of plant in the family Rosaceae from China were tested for anti-inflammatory activities. Samples were prepared using 95% ethanol using nitric oxide (NO) assay for assessing the anti-inflammatory activity. NO assay experiment showed that extracts of the Fissistigma poilanei give 28.3% increases in anti-inflammatory activity and extracts of Rubus laxus Focke give 57.1% decreases in anti-inflammatory activity, compared to control. To determine the cell toxicity, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used. MTT assay experiment showed that Fissistigma poilanei and Rubus laxus Focke might have less toxicity of 60.5% and 62.3%, respectively, compared to control. Taken together, these experiments showed that Fissistigma poilanei extracts might have significantly higher anti-inflammatory activities and relatively lower toxicity, compared to control. This implies that this study might give a tool to develop a new potential anti-inflammatory therapeutic candidate.

This study was investigated on anti-inflammatory and analgesic activity on Gu-Mi-Gang-Hwal-Tang which has been used for the treatment of common cold and headache, arthralgia, fever in oriental medicine. The anti-inflammatory activities of Gu-Mi-Gang-Hwal-Tang water extract (GMGHT) on the carrageenin induced edema, acetic acid induced edema, and corton oil induced granuloma pouch in rats were examined. The analgesic effect of the GMGHT was investigated utilizing acetic acid induced writhing syndrome in mice. The antipyretic activity of the GMGHT was also investigated. The oral administration of GMGHT has been shown the anti-inflammatory activities in 1% carrageenin and acetic acid induced edema in rats. The GMGHT has been shown significant inhibitory effects on glanuloma and exudate formation in rats, especially the GMGHT (450 mg/kg) has the efficacy more than the GMGHT (150 mg/kg). The writhing syndromes induced by acetic acid in mice were inhibited, especially analgesic activity of the GMGHT (450 mg/kg) is similar to that of piroxicam and antipyretic activities were recognized in rats. In the present study, the GMGHT is indicated to have the anti-inflammatory, analgesic and antipyretic activities.

Some pharmacological activities of acanthoic acid, isolated from Acanthopanax koreanum root was investigated in animals. It is revealed that the compound had analgesic and anti-inflammatory activities without actions on central nervous system and showed inhibition of lipid peroxidation. The anti-inflammatory activity might be related to inhibition of prostaglandin E$_2$ synthesis in exudates of inflammation.

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.

Talipariti hamabo is a plant growing around salt marshes in the Lava Coast region of Jeju Island, Korea. In this study, the extract of T. hamabo leaves was investigated for the anti-inflammatory, anti-oxidative and anti-bacterial activities and their active constituents were identified. In the anti-inflammatory tests using lipopolysaccharide-stimulated RAW264.7 cells, the ethyl acetate (EtOAc) fraction inhibited the nitric oxide production without causing cell toxicity. Moreover, the EtOAc fraction reduced pro-inflammatory cytokines (tumor necrosis factor-α, interleukin-6) as well as prostaglandin E₂. In the anti-oxidative studies with DPPH and ABTS⁺ radicals, potent scavenging activities were observed in the EtOAc and n-butanol fractions. Upon the anti-bacterial tests using Staphylococcus epidermidis, EtOAc and n-butanol fractions exhibited good activities. Through the phytochemical studies on EtOAc fraction, three components were isolated by repeated column chromatography; oleic acid (1), p-hydroxyphenethyl-trans-ferulate (2), nicotiflorine (3). Based on these results, the extract of T. hamabo leaves can be developed as natural resources for cosmetic applications.
