Brazilian ginseng, including Pfaffia townsendii, is used in popular medicine as a natural anti-inflammatory, tonic, analgesic, and antidiabetic agent. In this study, we investigated the chemical composition and evaluated the antioxidant and anti-inflammatory activities of the P. townsendii ethanolic extract as well as the major isolated glycoside flavonoids tiliroside and patuletin 3-O-β-D-glucopyranoside. Chromatographic techniques and spectroscopic analysis were used for the isolation and identification of the major compounds. The antioxidant potential was determined through DPPH and ORAC-FL assays. The total phenolic content was measured using Folin-Ciocalteu reagent. The anti-inflammatory activity was determined based on a model of paw edema and carrageenan- (Cg-) induced pleurisy. We identified three phenolic acids, one carboxylic acid and two flavonoids, patuletin 3-O-β-D-glucopyranoside, and tiliroside. The ethanol crude extracts, partitions and isolated flavonoids (4581 μmol of Trolox equivalents/g of extract in ORAC and a SC50 of approximately 31.9 μg/mL in the DPPH assay) demonstrated antioxidant activity, and the ethanolic extract as well as isolated flavonoids inhibited paw edema induced by Cg and leukocyte migration in the Cg-induced pleurisy model. The extract, tiliroside, and patuletin 3-O-β-D-glucopyranoside obtained from P. townsendii have therapeutic potential against oxidative stress-related and inflammatory disorders.

Osteoarthritis is a degenerative arthropathy that is mainly characterized by dysregulation of inflammatory responses. KMUP-1, a derived chemical synthetic of xanthine, has been shown to have anti-inflammatory and antioxidant properties. Here, we aimed to investigate the in vitro anti-inflammatory and in vivo anti-osteoarthritis effects of KMUP-1. Protein and gene expressions of inflammation markers were determined by ELISA, Western blotting and microarray, respectively. RAW264.7 mouse macrophages were cultured and pretreated with KMUP-1 (1, 5, 10 μM). The productions of TNF-α, IL-6, MMP-2 and MMP- 9 were reduced by KMUP-1 pretreatment in LPS-induced inflammation of RAW264.7 cells. The expressions of iNOS, TNF-α, COX-2, MMP-2 and MMP-9 were also inhibited by KMUP-1 pretreatment. The gene expression levels of TNF and COX families were also downregulated. In addition, KMUP-1 suppressed the activations of ERK, JNK and p38 as well as phosphorylation of IκBα/NF-κB signaling pathways. Furthermore, SIRT1 inhibitor attenuated the inhibitory effect of KMUP-1 in LPS-induced NF-κB activation. In vivo study showed that KMUP-1 reduced mechanical hyperalgesia in monoiodoacetic acid (MIA)-induced rats OA. Additionally, KMUP-1 pretreatment reduced the serum levels of TNF-α and IL-6 in MIA-injected rats. Moreover, macroscopic and histological observation showed that KMUP-1 reduced articular cartilage erosion in rats. Our results demonstrated that KMUP-1 inhibited the inflammatory responses and restored SIRT1 in vitro, alleviated joint-related pain and cartilage destruction in vivo. Taken together, KMUP-1 has the potential to improve MIA-induced articular cartilage degradation by inhibiting the levels and expression of inflammatory mediators suggesting that KMUP-1 might be a potential therapeutic agent for OA.

Phytochemicals possessing the antioxidant properties naturally present in food attract a greater interest to healthcare researchers due to their desirable health effects on human health as they can be explored for protection against oxidative deterioration. Macrtotyloma uniflorum is a leguminous plant belonging to the family Fabaceae and commonly known as Horse gram. Aqueous and ethanol extracts of seeds of Macrotyloma uniflorum were evaluated for their anti-inflammatory effects using the scientific protocol on experimental rats. Extraction was carried out using the cold maceration method, and the anti-inflammatory activity was evaluated using a digital plethysmometer in the experimental rats injected with carrageenan to produce paw edema. Preliminary phytochemical studies confirmed the presence of various bioactive compounds such as alkaloids, glycosides, carbohydrates, proteins and amino acids, terpenoids, tannins, and phenolic compounds in both extracts while flavonoids were found only in ethanol extract. Both extracts of M. uniflorum seeds (200 mg/ml) significantly (p<0.01) reduced the paw edema volume induced by carrageenan. The ethanol extract of M. uniflorum seeds exhibited more potent anti-inflammatory activity than water extract, that might be due to the presence of flavonoids in ethanol extract. The activity of the extracts was compared with diclofenac sodium (10mg/kg b.wt.) as a reference drug. From the results, it may be suggested that the antioxidative potential of phenolic constituents and flavonoids is the primary factors for the anti-inflammatory activity of M. uniflorum seeds extracts.

The presence of natural antioxidant in plants is well known. Plant phenolics constitute one of the major groups of components that act as antioxidant and free radical terminator. Hence, this study focused on investigating the antioxidant activity of Celery plant (Apium graveolens L). The fresh leaves were collected, crushed and extracted with ethanol and acetone by maceration. The radical scavenging properties of the extracts were determined by measuring changes in absorbance of DPPH radical at a wave lenght of 517 nm by UV and ascorbic acid is used as the standard. It showed that the crude ethanolic extract has higher antioxidant activity compared to ascorbic acid and acetone extract with less scavenging activity. The values were (IC50 114.6 µg/mL) for ascorbic acid, (IC50 112 µg/mL) for the crude ethanolic extract and (IC50172 µg/mL) for crude acetone extract. The result shows that Celery plant grown in Jos possess good antioxidant properties which may be linked to the presence of phenolics and flavonoids in the plant, which justifies its use as a medicinal plant. This can be further investigated for the isolation and identification of active compounds of medicinal utilities.

Chinese bayberry (Myrica rubra Sieb. et Zucc.) is an economically important medicinal plant with multiple uses. Two varieties ‘Dongkui Oriental Pearl’ (Dongkui for short) and acuminata ‘Nakai’ (Nakai for short) were used to compare and evaluate the antioxidant activities of hydroethanolic extracts of the fruit using ultrasonic and stirring extraction methods. Dongkui bayberry fruit extract (BFE) prepared using the ultrasonic method exhibited a significantly higher value for the total phenolic content (TPC) and had lower 50% inhibitory concentration (IC50) values of scavenging activities against 1,1-diphenyl-2- picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid (ABTS), and hydrogen peroxide (H2O2), as well as reducing power compared to the other treatment. The TPC of the BFE was significantly correlated with its DPPH, ABTS, and H2O2 radical-scavenging and reducing power activities. Dongkui BFE at a concentration of 0.25 mg/mL exhibited significantly greater protection of RAW 264.7 mouse macrophages against H2O2-induced damage and lipopolysaccharide (LPS)-stimulated nitric oxide production by macrophages, and it displayed remarkable inhibitory effects compared to the other extracts using the ultrasonic extraction method. Furthermore, compared to the Nakai BFE, macrophages exposed to the Dongkui BFE by the ultrasonic extraction method significantly inhibited LPS-induced production of tumor necrosis factor-α at a concentration of the extract of 0.25 mg/mL. The antioxidant properties and anti-inflammatory and protective effects of BFE prepared by stirring and ultrasonic methods are discussed for the first time in this study.   ********* In press - Online First.

Objective: A Bougainvillea x buttiana (var. Rose) Holttum and Standl extract (BxbREE) was prepared and its chemical composition, antioxidant and anti-inflammatory activity were evaluated.Methods: For the analyses of the phytochemical compounds present in BxbREE extract, gas chromatography-mass spectrometry (GC/MS) was used. To explore the anti-oxidant, anti-inflammatory activities, total phenolic contents, carbohydrates, lipids and carrageenan-induce paw edema models, respectively, were used. For in vivo experiments, the extract was orally, intraperitoneally and/or subcutaneously administered at doses of 0.04, 0.4, 4 and 40 mg/kg.Results: GC/MS analyses showed the presence of 7 compounds, including 2-Propenoic acid, 3-(2-hydroxyphenyl)-, (E)-(1.19%); 2-Methoxy-4-vinylphenol (0.22%); 3-O-Methyl-d-glucose (92.14%); n-Hexadecanoic acid (0.76%); Hexadecanoic acid, ethyl ester (1.17%); 9,12-octadecadienoic acid, ethyl ester (1.93%); and 9,12,15-Octadecatrienoic acid, ethyl ester (Z,Z,Z) (2.59%). Phytochemical qualitative analysis showed the presence of total phenolic contents at 320 mg of Gallic acid Equivalent/gram of dried extract (GA-Eq/g extract); carbohydrates 5.18 mg/ml and lipids 13.88 mg/ml. In accordance the structures the major compound was 3-O-Methyl-d-glucose. Our results also clearly indicate that BxbREE decreases inflammation in BALB/c mice as a subplantar injection of carrageenan-induced paw edema. The extract presented a potent dose-dependent inhibitory effect. The edema inhibition percentage was significantly lower in groups of animals treated with BxbREE by via intraperitoneal or subcutaneous when compared with those results obtained for groups treated by orally administration (p<0.001).Conclusion: In conclusion, this study established the anti-oxidant and anti-inflammatory activities of Bougainvillea x buttiana (var. Rose); also, this extract could be considered to be a natural anti-oxidant agent that represents an anti-inflammatory remedy.
