In the present study, the in vitro and in vivo anti-inflammatory effects of the sulfated polysaccharides isolated from Sargassum fulvellum (SFPS) were evaluated in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages and zebrafish. The results indicated that SFPS improved the viability of LPS-stimulated RAW 264.7 macrophages from 80.02 to 86.80, 90.09, and 94.62% at the concentration of 25, 50, and 100 µg/mL, respectively. Also, SFPS remarkably and concentration-dependently decreased the production levels of inflammatory molecules including nitric oxide (NO), tumor necrosis factor-alpha, prostaglandin E2, interleukin-1 beta, and interleukin-6 in LPS-treated RAW 264.7 macrophages. In addition, SFPS significantly inhibited the expression levels of cyclooxygenase-2 and inducible nitric oxide synthase in LPS-treated RAW 264.7 macrophages. Furthermore, the in vivo test results indicated that SFPS improved the survival rate of LPS-treated zebrafish from 53.33 to 56.67, 60.00, and 70.00% at the concentration of 25, 50, and 100 µg/mL, respectively. In addition, SFPS effectively reduced cell death, reactive oxygen species, and NO levels in LPS-stimulated zebrafish. Taken together, these results suggested that SFPS possesses strong in vitro and in vivo anti-inflammatory activities, and could be used as an ingredient to develop anti-inflammatory agents in the functional food and pharmaceutical industries.

In recent years, sprouted grains have become very popular and widely accepted as a functional food because of their nutritious and health benefits. So, this study was performed to evaluate the phytochemical com­position, and in vitro antioxidant capacity, reducing power, antihyperglycemic and anti-inflammatory activities, of seven-day old cereal sprouts (CS): Cultivars, barley NS565 (BSNS), barley Golozr­ni (BSG), wheat Spelta (WSSPE), wheat Simonida (WSSIM). Phenolic compounds were the most dominant bioactives in all CS. BSNS expressed significantly higher (p≤ 0.05) content of total phenols, chlo­rophyll and carotenoids. The total flavonoids content (TFC) in CS showed that barley sprouts (BSNS, BSG) had the higher value (P≤ 0.05) than wheat sprouts (WSSPE, WSSIM) respectively. The freeze-dried sprouts powders (FDSP) extracts were screened for possible antioxidant ca­pacities using DPPH, ABTS, and reducing power (Rp) assays. The results indicated that the BSNS possessed higher antioxi­dant capacities in DPPH and ABTS assays, and reducing power (IC50DPPH = 0.54 mg/ml; IC50ABTS = 0.79 mg/ml; IC0.5RP = 9.35 mg/ml) respectively. The inhibitory effect of FDSP extracts on α-glucosidase activity was investigated. The BSNS extracts exhibited higher inhibitory activity (IC50AHgA = 1.43 mg/ml) against α-glucosidase (p≤ 0.05). The anti-inflammato­ry activity (Denaturation of protein in vitro) showed signifi­cantly different between the FDSP, and Diclofenac sodium (DS). The IC50AIA of DS and BSNS was 0.79 and 1.86 (mg/ml) res­pectively. There was a strong positive correlation between TPC and antioxidant activities and reducing power, and also between TFC and anti-inflammatory activity.

The objectives of the study were to test the biological activities of peppermint and spearmint oils via (i) measuring in vitro anti-inflammatory effects with porcine alveolar macrophages (PAMs), (ii) determining the barrier integrity of IPEC-J2 by analyzing transepithelial electrical resistance (TEER), (iii) testing their antioxidant activities, and (iv) investigating the antimicrobial activity against enterotoxigenic Escherichia coli (ETEC) F18+. Briefly, (i) macrophages were seeded at 106 cells/mL and treated (24 h) with mint oils and lipopolysaccharide (LPS). The treatments were 2 (0 or 1 μg/mL of LPS) × 5 (0, 25, 50, 100, 200 µg/mL of mint oils). The supernatants were collected for TNF-α and IL-1β measurement by ELISA; (ii) IPEC-J2 cells were seeded at 5 × 105 cells/mL and treated with mint oils (0, 25, 50, 100, and 200 μg/mL). TEER (Ωcm2) was measured at 0, 24, 48, and 72 h; (iii) the antioxidant activity was assessed (0, 1, 50, 100, 200, 500, and 600 mg/mL) using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and reducing power assays; (iv) overnight-grown ETEC F18+ were quantified (CFU/mL) after supplementing with peppermint and spearmint oils (0, 1.44, 2.87, 5.75, 11.50, and 23.00 mg/mL). All data were analyzed using the MIXED procedure. Both mint oils significantly inhibited (p < 0.05) IL-1β and TNF-α secretion from LPS-stimulated PAMs. Mint oil treatments did not affect TEER in IPEC-J2. Spearmint and peppermint oils exhibited (p < 0.05) strong antioxidant activities in DPPH and reducing power assays. Both mint oils also dose-dependently inhibited (p < 0.05) the growth of ETEC F18+ in vitro. The results of the study indicated that both mint oils are great candidate feed additives due to their in vitro anti-inflammatory, antioxidant, and antimicrobial effects. Further research is needed to evaluate their efficacy in vivo.

The chemical machinery of vegetables offers a great diversity of biological properties and plays a fundamental role in the field of pharmacology. The search for new drugs with fewer adverse effects represents a challenge for researchers. The objective of the present work was to carry out to investigate the medicinal properties and safety of extracts and essential oil from aerial parts of Clinopodium gilliesii (muña muña) and evaluate their antioxidant and anti-inflammatory activities in vivo. The extractions were carried out serially, using 96º alcohol (EE) and boiled distilled water (AE). The essential oil (EO) was obtained by steam dragging. The AE in vivo anti-inflammatory activity was determined by carrageenan induced plantar edema (acute inflammation) and granuloma formation by cotton disc (chronic inflammation) at oral doses of 250 and 500 mg/kg while that of the EO was established topically at doses of 50, 100μl/kg. In-vitro antioxidant activity was evaluated by DPPH depuration and inhibition of lipid peroxidation (β-carotene-linoleic acid method). Chemical study of the extracts was carried out by means of phytochemical screening and the essential oil was analyzed by GC-MS chromatography. The safety was evaluated with test of acute toxicity (48 h) and acute dermal toxicity (14 days). The results revealed that EE and EO had a significant acute and chronic anti-inflammatory activity, compared with positive patterns. EE (500 mg/kg), EO (100μl/kg), ibuprofen (100 mg/kg) and meprednisone (5 mg/kg) significantly reduced the weight of the exudate and cotton disc granuloma (24.17, 35.30, 45.56 and 57.17% respectively). The alcoholic and aqueous extracts presented important antioxidant activities with values higher than 90% (from 400μg/ml) in both methods and similar to the positive patterns (BHT and quercetin). The chromatographic profile of volatile oil compounds showed a great richness in terpene substances, pulegone, menthone and neomenthol, being its major constituents. The hydroalcoholic extracts revealed the presence of reducing compounds, polysaccharides, tannins, triterpenes, sterols and coumarins as major phytoconstituents. In the acute toxicity study, a single dose of 4000 and 8000 mg/kg b.w., produced no mortality and no clinical signs of disease were observed after 48 h. The essential oil at a single dose of 2000 and 5000 mg/kg of body weight did not produce treatment-related signs of toxicity or mortality in all rats tested during the 14 day observation period. These findings are encouraging to continue studies for the validation of popular use and development of a phytopharmaceutical with medicinal utility.

Cecropia pachystachyais a species traditionally used in Brazil to treat inflammation. This work aims to evaluate the topical anti-inflammatory and antioxidant activities of the methanolic extract ofC. pachystachya(CPM) and to perform its chemical fingerprint by HPLC-DAD. The topical anti-inflammatory activity was evaluated using the mouse models of acute ear inflammation induced by croton oil, arachidonic acid, capsaicin, EPP, phenol, and chronic inflammation induced by multiple application of croton oil. Thein vitroantioxidant effect of CPM was investigated using DPPH, reducing power,β-carotene bleaching, and TBARS assays. HPLC analysis was performed to quantify the antioxidant phenolics orientin, isoorientin, and chlorogenic acid previously identified in CPM. CPM exhibited significant anti-inflammatory effect in the acute models, in some cases comparable to the reference drugs. Histopathological analysis showed a moderate chronic skin anti-inflammatory effect with decrease in vasodilation, edema, cell infiltration, and epidermal hyperproliferation. It also showed strongin vitroantioxidant activity. The contents of orientin, isoorientin, and chlorogenic acid were 66.5 ± 1.8, 118.8 ± 0.7, and 5.4 ± 0.2 µg/mg extract, respectively. The topical anti-inflammatory activity of CPM could be based on its antioxidant properties, although other effects are probably involved, including COX inhibition and other mechanisms.

Aim: This study was carried out to investigate the antioxidant and antimicrobial activities of essential oil from the aerial part of Caralluma europaea and to evaluate the synergistic potential between essential oil and antibiotics. Methodology: The chemical composition, antioxidant, antimicrobial activities and synergetic interaction between antimicrobial agents and essential oil isolated by hydrodistillation from the aerial part of C. europaea were evaluated. The chemical composition was analyzed by a Gas chromatography/mass spectrometry (GC/MS) system. Antioxidant activity was measured employing three methods: scavenging of free radical DPPH, reducing power assay and the inhibition of linoleic acid oxidation. The antimicrobial activity of essential oil against microbial strains was qualitatively and quantitatively assessed by the presence or absence of inhibition zones diameters, and MIC values. The in vitro association between essential oil and some commercial antibiotics was also investigated. Results: The GC/MS analysis shows that a total of 21 constituents were identified and the main compounds were Terpinolene (19.5%), α-Terpinene (16.2%) and Linalool (15.3%). Antioxidant study showed that essential oil exhibited antioxidant activity with IC50 values ranging from 0.32 mg/ml to 1.45 mg/ml. The results of antimicrobial activity showed that the essential oil had an inhibitory effect against the majority of tested microorganisms except K. pneumonia and  P. aeruginosa. Gram-positive bacteria were found to be more sensitive than Gram-negative ones. Furthermore, essential oil approved an interesting antifungal activity against yeast species. Out of 25 combinations tested 64% showed total synergism, 20% had a partial synergistic interaction and 16% showed no effect. The best synergistic effect was obtained with the combination essential oil-gentamycin. Conclusion: Our results are of a great importance and suggest that C. europaea essential oil contain bioactive compounds with antioxidant and antimicrobial properties with possible applications in the food and pharmaceutical industries.
