  • Previously, we reported that the n-butanol fraction of Lonicera japonica showed anti-flammatory activity in mice and rats. Several constituents such a loniceroside A and B, flavonoids and iridoids were isolated from this fraction. In this investigation, the anti-inflammatory activity of the major constituents of L. japonica was studied. Loniceroside A, lonicerin and loganin showed anti-inflammatory activity comparable to aspirin.

  • Background : We studied the anti-oxidant activity and anti-inflammatory effects of Spiraea fritschiana Schneid extract (SFSE). Methods and Results : The SFSE was prepared using methanol and was evaluated for its total phenol and flavonoid content, DPPH (1,1-diphenyl-2-picrylhydrazyl) free-radical scavenging activity, reducing power, and effect on nitric oxide (NO) production, and cell viability by using real-time polymerase chain reaction (PCR). The total phenol content was $212.78{\mu}g{\cdot}galli$c acid equivalent (GAE)/mg and the total flavonoid content was $66.84{\mu}g{\cdot}quercetin$ equivalent (QE)/mg. The extract showed antioxidant activity (DPPH free-radical scavenging activity) with $RC_{50}$ value of $76.61{\mu}g/m{\ell}$. The reducing power of the extract was Abs 0.58 at $250{\mu}g/m{\ell}$. Cell viability was determined using the MTT 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. To evaluate anti-inflammatory activity, we examined the inhibitory effects on lipopolysaccharide-(LPS)-induced NO production in RAW 264.7 cells. The NO inhibition rate was 90% at $200{\mu}g/m{\ell}$ SFSE. At the same concentration, the expression of pro-inflammatory genes such as inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 also decreased. Conclusions : Our results suggest that SFSE is a novel resource for the development of foods and drugs that possess anti-oxidant and anti-inflammatory activity.

  • This study screened the antimicrobial and anti-inflammatory activities of three extracts [1% acetic acid (HAc), distilled water (D.W.), and ethanol] from the common stalked barnacle Pollicipes mitella. Among the extracts, the 1% HAc extract showed the strongest antibacterial activity against several bacteria, but exhibited no activity against Candida albicans. To improve the degree of separation of the 1% HAc extract, solid-phase extraction was performed using a C18 cartridge with three solvents (D.W., 60A, and 100A). The 1% HAc 60A eluate showed the strongest antibacterial activity and enzyme, salt, and temperature stability, with no hemolytic activity. In addition, strong DNA-binding ability but no bacterial membrane permeability was observed. These results indicate that the P. mitella 1% HAc 60A eluate may contain antibacterial organic compounds that target intracellular components but not bacterial membranes. In addition, the 1% HAc 60A eluate exhibited potent inhibitory activity to reduce the production of inflammatory mediators (nitric oxide and prostaglandin E2) and pro-inflammatory cytokines (tumor necrosis factor-α, interleukin (IL)-6, and IL-1β) with no cytotoxicity. Therefore, the P. mitella 1% HAc 60A eluate has anti-inflammatory activity. Collectively, our results suggest that the P. mitella 1% HAc 60A eluate can be used as a bioactive source with antibacterial and anti-inflammatory activities.

  • Background: The objective of this study was to investigate antioxidant and anti-inflammatory activity of cabbage phytochemicals. Materials and Methods: Color coordinates were evaluated by colorimetry, and the antioxidant and anti-inflammatory activities were analyzed by spectrophotometer for some common cabbage varieties. Results: Red heads had the highest total antioxidant contents followed by Savoy, Chinese and green heads. The Chinese variety had the highest ABTS (2,2-azino-di-(3-ethylbenzthiazoline-sulfonic acid) antioxidant activity, was 5.72 ${\mu}mol$ TE/g fw (Trolox equivalent). The green variety had the highest DPPH (free radical scavenging activity) antioxidant activity, which was 91.2 ${\mu}mol$ TE/g fw. The red variety had the highest FRAP (ferric reducing antioxidant power) antioxidant activity, which was 80.8 ${\mu}mol$ TE/g fw. The total phenol amounts were 17.2-32.6 mM trolox equivalent antioxidant capacity (TEAC) and the total flavonoid amounts were 40.0-74.2 mg quercetin per gram. Methanolic extracts of different cabbage heads showed different anti-inflammatory activity values. Chinese, Savoy and green heads had the highest anti-inflammatory activity, while red heads had the lowest. Conclusions: The results suggest that these varieties of cabbage heads could contribute as sources of important antioxidant and anti-inflammatory related to the prevention of chronic diseases associated to oxidative stress, such as in cancer and coronary artery disease.

  • Synurus deltoides was previously found to possess significant anti-inflammatory activity especially against chronic inflammation, and strong analgesic activity in vivo. In this study, new anti-inflammatory formulation containing S. deltoides extract as a major ingredient was prepared and in vivo activity was evaluated. The plausible action mechanism was also investigated. The new formulation (SAG) contains 1 part of S. deltoides extract, 0.9 part of Angelica gigas extract and 0.9 part of glucosamine sulfate (w/w). SAG inhibited dose-dependently edematic response of arachidonic acid (AA)- and 12-O-tetradecanoyl 13-acetate (TPA)-induced ear edema in mice, which is an animal model of acute inflammation. SAG showed 44.1 % inhibition of AA-induced ear edema at an oral dose of 50 mg/kg. In an animal model of chronic inflammation, SAG clearly reduced the edematic response of 7 -day model of multiple treatment of TPA (38.1 % inhibition at 200 mg/kg/day). Furthermore, SAG (50-800 mg/kg/day) as well as S. deltoides extract (285 mg/kg/day) significantly inhibited prostaglandin $E_2$ production from the skin lesion of the animals of 7-day model. These results were well correlated with in vitro finding that SAG as well as S. deltoides extract reduced cyclooxygenase (COX)-1- and COX-2-induced prostanoid production, measured in mouse bone marrow-derived mast cells. Therefore, these results suggest that SAG possesses anti-inflammatory activity in vivo against acute as well as chronic inflammatory animal models at least in part by inhibition of prostaglandin production through COX-1/COX-2 inhibition. And COX inhibition of SAG is possibly contributed by S. deltoides extract among the ingredients. Although the anti-inflammatory potencies of SAG were less than those of currently used anti-inflammatory drugs, this formulation may have beneficial effect on inflammatory disorders as a neutraceutical.

  • Anti-infammatory, analgesic and ulcerogenic activities of fentiazac were investigated in comparison with those of acetylsalicylic acid, fenbufen, naproxen and phenylbutazone. On the anti-inflammatory activity in carrageenin-induced rat paw edema and the analgesic activity on writhing syndrome induced with acetic acid in mice, fentiazac displayed more potent effect than acetylsalicylic acid, fenbufen and pbenylbutazone. But the ulcerogenic action of fentiazac on gastrointestinal tract in fasting rats was less than that of reference drugs. From these investigation, fentiazac seemed to indicate a poor correlation between the extent of anti-inflammatory activity and ulcerogenic action.

  • The aim of this study was to measure and compare polyphenol content, antioxidant, and anti-inflammatory activity of six halophytes (Limonium tetragonum, Suaeda glauca, Suaeda japonica, Salicornia europaea, Triglochin maritimum, and Sonchus brachyotus). Depending on the total polyphenol content, the plants were categorized into two groups: (1) a high total polyphenol content group that included L. tetragonum, S. brachyotus, and S. europaea, and, (2) a low total polyphenol content group consisting of S. glauca, T. maritima, and S. japonica. Antioxidant activity was evaluated using DPPH and hydroxyl radical scavenging assays, and by measuring ROS. Anti-inflammatory activity was evaluated by measuring NO and $PGE_2$. L. tetragonum and S. brachyotus, that have high polyphenol content, also showed strong antioxidant activity. In addition, L. tetragonum, S. brachyotus, and S. europaea showed good anti-inflammatory activity. Consequently, the total polyphenol content was thought to be related to antioxidant and anti-inflammatory activity. Therefore, S. brachyotus and L. tetragonum are good candidates for use in pharmaceuticals and functional foods.

  • Cordyceps bassiana is one of Cordyceps species with anti-oxidative, anti-cancer, anti-inflammatory, anti-diabetic, anti-obesity, anti-angiogenic, and anti-nociceptive activities. This mushroom has recently demonstrated to have an ability to reduce 2,4-dinitrofluorobenzene-induced atopic dermatitis symptoms in NC/Nga mice. In this study, we further examined phytochemical properties of this mushroom by column chromatography and HPLC analysis. By chromatographic separation and spectroscopic analysis, 8 compounds, such as 1,9-dimethylguanine (1), adenosine (2), uridine (3), nicotinamide (4), 3-methyluracil (5), 1,7-dimethylxanthine (6), nudifloric acid (7), and mannitol (8) were identified from 6 different fractions and 4 more subfractions. Through evaluation of their anti-inflammatory activities using reporter gene assay and mRNA analysis, compound 1 was found to block luciferase activity induced by $NF-{\kappa}B$ and AP-1, suppress the mRNA levels of cyclooxygenase (COX)-2 and tumor necrosis factor $(TNF)-{\alpha}$. Therefore, our data strongly suggests that compound 1 acts as one of major principles in Cordyceps bassiana with anti-inflammatory and anti-atopic dermatitis activities.

  • In this study we investigated antioxidant and anti-inflammatory activities of Malus Domestica (apple), Pyrus Communis L. (pear), Daucus carota L. (carrot), Brassica oleracea var. (broccoli), Brassica oleracea var. capitata (cabbage) and Raphanus sativus L. (radish), that were obtained from local market. As these are common fruits and vegetables that are widely consumed, we aimed to investigate their beneficial properties especially the antioxidant and anti-inflammatory. The samples were processed by an indirect heating method and their properties were compared to their raw forms. Based on DPPH and ABTS assay, processed samples showed better antioxidant activity compared to raw samples, and processed pear sample had the best antioxidant activity. The anti-inflammatory activities of the samples were also investigated in LPS-treated RAW 264.7 cells. The mRNA expressions of pro-inflammatory mediators and cytokines (iNOS, COX-2, $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6) were assessed by RT-PCR. Processed samples exhibited better inhibition of iNOS, compared to the raw forms. Processed broccoli and cabbage samples exhibited outstanding anti-inflammatory effects. The samples did not exhibit cytotoxicity against RAW 264.7 cells up to 1mg/ mL as shown in the cell viability assay. Taken together, processed broccoli and cabbage samples exhibited the strongest anti-inflammatory properties.

  • Zizyphus jujube is a plant in the buckthorn family (Rhamnaceae) that has been the subject of research into antibacterial, antifungal and anti-inflammatory properties of its fruit and seed. However, few studies have investigated its leaves. In this study, the anti-inflammatory activity of ZJL (an extract of Z. jujube leaf) was evaluated to verify its potential as an anti-inflammatory agent and SARS-CoV-2 medicine, using nitric oxide (NO) assay, RT-PCR, SDSPAGE, Western blotting, and UHPLC/TOFHRMS analysis. We found that ZJL suppresed pro-inflammatory mediators such as NO, inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and tumor necrosis factor α (TNF-α) in lipopolysaccharide (LPS)-induced RAW264.7 cells. ZJL acted by inhibiting NF-KB and MAPK signaling pathway activity. We also confirmed that ZJL contains a phenol compound and flavonoids with anti-inflammatory activity such as trehalose, maleate, epigallocatechin, hyperoside, catechin, 3-O-coumaroylquinic acid, rhoifolin, gossypin, kaempferol 3-neohesperidoside, rutin, myricitrin, guaiaverin, quercitrin, quercetin, ursolic acid, and pheophorbide a. These findings suggest that ZJL may have great potential for the development of anti-inflammatory drugs and vaccines via inhibition of NF-κB and MAPK signaling in LPS-induced RAW264.7 cells.
