Phaseolus aureus (mung bean), Leguminosae, has been used as an antidote from the ancient time. Especially, it has been widely used for cleaning face and skin in oriental countries. Although several constituents such as fatty acids, phytoallexin and phaseol derivatives were reported in P. aureus and related species including seedlings, there has been a few report to describe its biological activity. Therefore, in this investigation, the ethanol extract from P. aureus was obtained and its biological activities including the antioxidative and anti-inflammatory activities were studied. The 70% ethanol extract from P. aureus showed dose-dependent antioxidative activity (52.3% inhibition at 4 mg/ml) against lipid peroxidation assay, while the extract did not show the inhibitory activity of superoxide radical formation. The extract also showed the topical anti-inflammatory activity against croton-oil and arachidonic acid induced mouse ear edema test (18-19% inhibition at 7.5 mg/ear) as well as mild inhibitory activity against picryl chloride induced delayed hypersensitivity in mouse. For investigating active principles, vitexin and isovitexin (apigenin C-glycoside) as flavonoids, and adenosine were isolated from the extract using silica gel chromatography. The actual contents of vitexin and isovitexin were found to be 3.7 and 2.4 mg/g extract, respectively. Vitexin and isovitexin showed the antioxidative activity. They showed the topical anti-inflammatory activity, although the activities were not potent compared to the reference compounds. These results suggested that vitexin and isovitexin may be, at least in part, the compounds contributing the antioxidative activity in vitro and the topical anti-inflammatory activity of P. aureus in vivo. All results of present study might be one of the scientific rationale in using mung bean for skin care from the ancient time.

Background: Korean ginseng (Panax ginseng) plays an anti-inflammatory role in a variety of inflammatory diseases such as gastritis, hepatitis, and colitis. However, inflammation-regulatory activity of the calyx of the P. ginseng berry has not been thoroughly evaluated. To understand whether the calyx portion of the P. ginseng berry is able to ameliorate inflammatory processes, an ethanolic extract of P. ginseng berry calyx (Pg-C-EE) was prepared, and lipopolysaccharide-activated macrophages and HEK293 cells transfected with inflammation-regulatory proteins were used to test the anti-inflammatory action of Pg-C-EE. Methods: The ginsenoside contents of Pg-C-EE were analyzed by HPLC. Suppressive activity of Pg-C-EE on NO production, inflammatory gene expression, transcriptional activation, and inflammation signaling events were examined using the Griess assay, reverse transcription-polymerization chain reaction, luciferase activity reporter gene assay, and immunoblotting analysis. Results: Pg-C-EE reduced NO production and diminished mRNA expression of inflammatory genes such as cyclooxygenase-2, inducible NO synthase, and tumor necrosis factor-${\alpha}$ in a dose-dependent manner. This extract suppressed luciferase activity induced only by nuclear factor-${\kappa}B$. Interestingly, immunoblotting analysis results demonstrated that Pg-C-EE reduced the activities of protein kinase B (AKT)1 and AKT2. Conclusion: These results suggest that Pg-C-EE may have nuclear-factor-${\kappa}B$-targeted anti-inflammatory properties through suppression of AKT. The calyx of the P. ginseng berry is an underused part of the ginseng plant, and development of calyx-derived extracts may be useful for treatment of inflammatory diseases.

The anti-inflammatory activity of the aqueous extract from Gleditsiae spina was investigated utilizing carrageenin-induced edema, granuloma pouch and adjuvant arthritis in rats. The effects of this agent on vascular permeability and acetic acid-induced writhing in mice were also examined. Its anti-inflammatory activity on carrageenin edema was observed with oral administration. The aqueous extract from Gleditsiae spina(400 mg/kg, 7 days) showed significant inhibitory effects on granuloma and exudate formation in rats. In the method of adjuvant arthritis, the aqueous extract(400 mg/kg), orally administered for 21 days, inhibited the development of hind paw edema in rats. The aqueous extract was also inhibited the increase in vascular permeability and the number of writhings induced by acetic acid in mice. In the present study, the aqueous extract of Gleditsiae spina was indicated to have the anti-inflammatory action.

Most inflammatory disorders are usually treated using anti-inflammatory drugs including non-steroidal anti-inflammatory drugs (NSAID) and steroidal anti-inflammatory drugs (SAID). In a prolonged use, however, they may frequently produce adverse side-effects. Thus, it is necessarily required to develop a new anti-inflammatory drug with little side-effects. Nephrite has been widely used by traditional oriental medicine to cure the various chronic diseases. In order to verify the anti-inflammatory activity of nephrite, the TPA (12-O-tetradecanoylphorbol-acetate) or the croton oil-induced edema was developed in the mouse ears and the nephrite powder suspension or the nephrite water was directly applied to the ear edema. It was found that nephrite could significantly reduce the ear swelling implying its strong potential as an active anti-inflammatory agent when comparing to indomethacin, a non-steroidal anti-inflammatory drug.

Fisetin is a naturally occurring flavonoid with some anti-cancer and anti-inflammation capabilities. In this study, we perform docking studies between human c-Jun N-terminal kinase 1 (JNK 1) and fisetin and proposed a binding model of fisetin and JNK 1, in which the hydroxyl groups of the B ring and oxygen at the 4-position of the C ring play key roles in binding interactions with JNK. Fluorescence quenching and saturation-transfer difference (STD) NMR experiments showed that fisetin exhibits good binding affinity to JNK, $1.32{\times}10^8M^{-1}$. The anti-inflammatory activity of fisetin was also investigated. Fisetin significantly suppressed tumor necrosis factor, the NO production, and macrophage inflammatory cytokine release in LPS-stimulated RAW264.7 mouse macrophages. We found that the anti-inflammatory cascade of fisetin was mediated through the JNK, and cyclooxygenase (COX)-2 pathways. Our findings suggest the potential of fisetin as an anti-inflammatory agent.

Although marine living organism contains a numerious number of compounds, it is difficult to collect these compounds in a large scale for medicinal application. However, in recent years, several bioactive compounds isolated from marine macroalgae have been proved to be able to provide potential sources for development of medicinal products because they can be obtained in large amount from marine. A number of studies have reported a variety of effects of marine macroalgae but a few anti-inflammatory activity of marine macroalgae have recently been published. Herein, we reviewed novel anti-inflammatory compounds recently isolated from marine brown algae, green algae and red algae. From this survey, in particular, some compounds contained in edible macroalgae exert anti-inflammatory effects with inhibition on cyclooxygenase-2 (COX-2), inducible nitric oxide synthase(iNOS) and matrix metalloproteinases (MMPs) activity regulated by nuclear factor-kappa B transcription factor that play a key role in cancer as well as inflammation, demonstrating to be able to potentially apply to development of anti-inflammatory agent for chemoprevention of cancer. Furthermore, some macroalgae and their compounds with both excellent anti-inflammatory activity and very low toxicity can select a potential candidates capable of preventing or treating several chronic inflammation such as colitis, hepatitis and gastritis, leading to cancer.

Objectives: This study was to investigate the anti-oxidative and anti-inflammatory effect of Psoralea corylifolia water extract (PE) on ulcerative colitis which was induced by dextran sulfate sodium (DSS) in mice. Methods: Ulcerative colitis was induced by DSS in male BALB/c mice. The mice were divided into 3 groups. The control group (Ctrl) was not induced ulcerative colitis. The pathological group (CE) was induced the colitis. The experimental group (PT) was administered PE after inducing the colitis. The effects of the PE on ulcerative colitis were evaluated by morphological change in the colon tissue and cells, substance P production, activity of tumor necrosis factor $(TNF)-{\alpha}$ and nuclear factor $(NF)-{\kappa}B$, cyclooxygenase (COX)-2 production, and anti-oxidative activity. Results: In the PT group, PE alleviated hemorrhagic erosion in colon mucosa and infiltration of inflammatory cells in lamina propria mucosae. In the colon of the PT group, COX-2 production was inhibited via regulating the activity of $TNF-{\alpha}$ and $NF-{\kappa}B$ p65. PE also had an anti-oxidative effect via activating nuclear factor (erythroid-derived 2)-like 2 (Nrf2). Conclusions: In this study, we found the utility of treatment with PE and the potential of developing a medicine for ulcerative colitis by applying our results. Further investigations for the anti-inflammatory mechanism of PE may be needed.
