In an attempt to elucidate the anti-inflammatory action of ginseng total saponin, protopanaxadiol and protopanaxatriol, the anti-inflammatory activity of three compounds was investigated under various acute and chronic inflammatory models. The blood vessel permeability was slightly inhibited by total saponin and protopanaxatriol treatments. Granuloma formation induced by 2% carrageenan was inhibited by total saponin and protopanaxatriol. The cotton-pellet granuloma formation was significantly inhibited by intraperitoneal injection of total saponin. Total saponin and protopanaxadiol inhibited leukocyte emigration and protein exudation in CMC-induced pouch but protopanaxauiol increased leukocyte emigration. The swelling of rat hind paw induced by 1% carrageenan was significantly inhibited by total saponin, protopanaxadiol and protopanaxatriol both single and 2 weeks treatments. Total saponin, protopanaxadiol and protopanaxatriol decreased the anti-inflammatory activity in adrenalectomized rat. Our results suggest that total saponin, protopanaxadiol and protopanaxatriol have potent anti-inflammatory activity, this may be mediated in part through stimulation of adrenal glands.

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.

Biflavonoid is one of unique classes of naturally-occurring bioflavonoids. Certain biflavonoids including amentoflavone were previously reported to have inhibitory effect on the group 11 phospholipase $A_2$ activity. Amentoflavone was also found to inhibit cyclooxygenase from guinea-pig epidermis without affecting lipoxygenase. In this study, anti-inflammatory and analgesic activities of amentoflavone were evaluated. When amentoflavone was administered intraperitoneally, it showed a potent anti-inflammatory activity as determined by amelioration of croton-oil induced mouse ear edema. It also showed a potent anti-inflammatory activity in the rat carrageenan paw edema model ($ED_{50}$=42 mg/kg) compared to the activity of prednisolone (35 mg/kg) and indomethacin (10 mg/kg). However, amentoflavone did not show a significant inhibitory activity against rat adjuvant-induced arthritis, a chronic inflammatory model. In addition, amentoflavone was found to possess a potent analgesic activity in the acetic acid writhing test ($ED_{50}$=9.6 mg/kg) compared to the activity of indomethacin (3.8 mg/kg). These results suggest that amentoflavone may be a potential lead for a new type of anti-inflammatory agents having dual inhibitory activity of group 11 phospholipase $A_2$ and cyclooxygenase.

Red rose petals are usually disposed but they are an abundant source of phenolics and traditionally used as food supplement and as herbal medicine. Of the Various phenolics, they are known to have anticancer, antioxidant, and anti-inflammatory properties. In this study, we investigated the anti-inflammatory effects of red rose ethanolic extracts (GRP) on lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results demonstrated that pretreatment of GRP (500㎍/mL) significantly reduced NO production by suppressing iNOS protein expression in LPS-stimulated cells. Anti-inflammatory effects by red rose petals were observed in the following. Red rose petals inhibited the translocation of NF-κB from the cytosol to the nucleus via the suppression of IκB-α phosphorylation and also inhibited LPS-stimulated NF-κB transcriptional activity. These findings suggest that red rose petals exert anti-inflammatory actions and help to elucidate the mechanisms underlying the potential therapeutic values of red rose petals. Therefore, red rose petals could be regarded as a potential source of natural anti-inflammatory agents.

The anti-inflammatory activity of acetylsalicylic acid maltol ester (aspalatone), a potential anti-thombotic agent, was studied using the several experimental animal models of inflammation. By oral administration, aspalatone was found to possess the weak anti-inflammatory activity in models of an acute inflammation, in which aspalatone showed approximately one-third to one-fourth of the anti-inflammatory activity of aspirin. Aspalatone (200 mg/kg/day) and aspirin (50 mg/kg/day), however, did not show the inhibitory activity against granuloma fomation and adjuvant-induced arthritis.

The study was conducted to identify the anti-inflammatory and anti-cancer effects in sprouts of mouse-eyed bean (Rhynchosia nulubilis), ginseng (Panax ginseng), perilla (Perilla frutescens), broccoli (Brassica oleracea var. italica), and lettuce (Lactuca sativa) grown with organic germanium concentrate. Western blot analysis was performed to assess the anti-inflammatory activity of the extract. All extracts exhibited noticeable anti-oxidant activity, indicating a significant correlation between the germanium content and anti-oxidant activity (p<0.05). In particular, rat-eyed bean sprouts with the highest germanium content showed significant anti-inflammatory activity (p<0.05) by significantly inhibiting the expression of the inflammatory complexes, NLRP3, cytokines IL-1β and caspase-1. Ginseng and broccoli sprouts showed strong anti-cancer properties and had high anti-oxidant effects (p<0.001). Germanium-concentrated water allows the mass production of agricultural products containing high concentrations of organic germanium. Agricultural produce grown with germanium concentrate add organic germanium to various physiological active ingredients, increasing the anti-oxidant and anti-cancer effects. These results strongly suggest that agricultural products containing high germanium concentrations can be used as novel health supplements to improve health.

Previous screening of the pharmacological action of Gastrodia elata (GE) root (Orchidaceae) showed that methanol (MeOH) extracts have significant anti-inflammatory properties. The antiinflammatory agents of GE, however, remain unclear. In this experiment, MeOH extracts of GE were fractionated with organic solvents for the anti-inflammatory activity-guided separation of GE. Eight phenolic compounds from the ether (EtOEt) and ethyl acetate (EtOAc) fractions were isolated by column chromatography: 4-hydroxybenzaldehyde (I), 4-hydroxybenzyl alcohol (II), benzyl alcohol (III), bis-(4-hydroxyphenyl) methane (IV), 4(4'-hydroxybenzyloxy)benzyl-methylether (V), 4-hydroxy-3-methoxybenzyl alcohol (VI), 4-hydroxy-3-methoxybenzaldehyde (VII), and 4-hydroxy-3-methoxybenzoic acid (VIII). To investigate the anti-inflammatory and anti-oxidant activity of these compounds, their effects on carrageenan-induced paw edema, arachidonic acid (AA)-induced ear edema and analgesic activity in acetic acid (HAc)-induced writhing response were carried out in vivo; cyclooxygenase (COX) activity, reactive oxygen species (ROS) generation in rat basophilic leukemia (RBL 2H3) cells and 1,1-diphenyl-2-picryl-hydroazyl (DPPH) scavenging activity were determined in vitro. These phenolic compounds not only had anti-inflammatory and analgesic properties in vivo, but also inhibited COX activity and silica-induced ROS generation in a dose-dependent manner. Among these phenolic compounds, compound VII was the most potent anti-inflammatory and analgesic. Compound VII significantly inhibited silica-induced ROS generation and compound VI significantly increased DPPH radical scavenging activity. Compounds I, II and III significantly inhibited the activity of COX-I and II. These results indicate that phenolic compounds of GE are anti-inflammatory, which may be related to inhibition of COX activity and to anti-oxidant activity. Consideration of the structure-activity relationship of the phenolic derivatives from GE on the anti-inflammatory action revealed that both C-4 hydroxy and C-3 methoxy radicals of benzyl aldehyde play an important role in anti-inflammatory activities.

In this study, we investigated the antioxidant and anti-inflammatory effect of the Paulownia tomentosa extracts (PTE). The total polyphenol and flavonoid contents of PTE were 148.98±1.84 mg GAE/g extract, and 115.33±4.16 mg CE/g extract, respectively. The PTE showed that strong antioxidant activity via -diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, ABTS radical scavenging activity and FRAP assay. The anti-inflammatory activity was evaluated on lipopolysaccharide (LPS)-stimulated RAW264.7 cells. PTE remarkably reduced protein expression of inducible nitric oxide (iNOS), resulting in inhibition of production of nitric oxide (NO). Additionally, pre-treatment of PTE significantly suppressed the production of inflammatory cytokines, such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Moreover, PTE significantly attenuated LPS-induced IkappaB (IκB) degradation and suppressed nuclear factor kappa B (NF-κB) nuclear translocation in macrophages. The PTE showed high antioxidant and anti-inflammatory activity. These data suggest that PTE has pharmacological activity and may be useful for the development of anti-inflammatory agents.
