Vitellaria paraodoxa (shea tree) is the source of shea seed from which the well-known shea butter is derived. The methanol extract of shea seed was evaluated for its anti-inflammatory and antioxidant activities using diclofenac sodium and ascorbic acid as standard respectively in in vitro methods. The anti-inflammatory activity was determined by inhibition of protein denaturation of bovine serum albumin (BSA) and erythrocyte membrane stabilization of human red blood cell. The antioxidant activity was evaluated using 1, 1-diphenyl-2-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), thiobarbituric acid reactive substances (TBARS) and total antioxidant capacity (TAC) assays. The results showed that methanol extract of V. paradoxa seed at different concentration protects the heat induced protein denaturation with the maximum percentage inhibition of 27% (IC50=303.0 µg/mL, p<0.05) at 500µg/mL compared to the standard drug which induced maximum inhibition of 45% (IC50=261.4 µg/mL, p<0.05) at 500 µg/mL and the control. The percentage inhibition of the methanol extract and standard drug in erythrocyte stabilization assay increased in a concentration dependent manner with maximum inhibitory activity of 96.9% (IC50=31.47 µg/mL, p<0.05) and 95% (IC50=33.89 µg/mL, p<0.05) at 2000 µg/ml respectively, which indicates that methanol extract stabilized erythrocyte membrane against hypotonic induced hemolysis in a blood sample better than the standard drug. The maximum percentage inhibition of methanol extract and standard drug in DPPH assay were found to be at 97% (IC50=8.95 µg/mL, p<0.05) and 98% (IC50=6.72 µg/mL, p<0.05) respectively at 100 µg/ml. The absorbance of the reductive capacities in FRAP assay indicates that the methanol extract has higher reducing potency in a concentration dependent manner. The methanol extract exhibited total antioxidant capacity of 0.25 ± 0.04 µg/(AAE/g) when compared to the standard drug 0.87 ± 0.03 µg/(AAE/g) at highest concentration of 100 µg/ml. For TBARS assay, low absorbance value indicate a high level of inhibition of lipid peroxidation. The maximum percentage inhibition of methanol extract was 97.5 % (IC50=51.79 µg/mL, p<0.05) and ascorbic acid was 99% (IC50=52.30 µg/mL, p<0.05) at concentration of 20 µg/ml. The assay indicates that the methanol extract has higher inhibiting potency in a reverse concentration dependent manner. In conclusion, V. paradoxa seed may possess strong anti-inflammatory and antioxidant activities which could constitute a potential source for development of new therapy.

ABSTRACT Indigofera linnaei Ali. (Tamil Name: Cheppu Nerinjil) belongs to the family Fabaceae, used for the treatment of various ailments in the traditional system of medicine. In the present study, the beneficial effects of methanol extract of whole plant of I. linnaei (MEIL) were evaluated on inflammation and nociception responses in rodent models. In vitro nitric oxide (NO), lipoxygenase (LOX) and cyclooxygense (COX) inhibitory activities were also performed to understand the mode of action. MEIL at the dose of 200 & 400 mg/kg, p.o. significantly inhibited carrageenan induced rat paw volume and reduced the weight of granuloma in cotton pellet granuloma model. The results obtained were comparable with the standard drug aceclofenac. The anti-nociceptive effect of MEIL in mice was evaluated in hot plate and acetic acid induced writhing model. The plant extract significantly reduced the number of writhes and the analgesic effect was higher than that of the standard drug aspirin. However, the extract fails to increase the latency period in hot plate method suggesting that the extract produce nociception by peripheral activity. The extract produced inhibitory effect on NO, LOX and COX in concentration dependent manner. The extract exhibited pronounced and selective COX-2 inhibition. Altogether, these results suggested that the methanol extract of Indigofera linnaei could be considered as a potential anti-inflammatory and analgesic agent.

Abstract Background The study sought to investigate the biological efficacy of methanol leave extract of Acacia auriculiformis (MEAA) via in vitro, in vivo, in silico approaches. The in vitro cytotoxicity was evaluated through brine shrimp lethality assay, and anti-inflammatory activity was determined by membrane stabilisation and protein denaturation methods (BSA and egg albumin). The in vivo antipyretic activity was examined via Brewer’s yeast induced pyrexia model. Results A. auriculiformis extract unveiled moderate cytotoxicity with significant anti-inflammatory efficacy (p < 0.001) compared to standard drug. This extract also exhibited dose-dependent time of paralysis and death for the worm (p < 0.001) in the anthelmintic test which was directly proportional to employed concentrations. A notable percentage of clot lysis effect (36.42 ± 1.95%, p < 0.001) was also observed for MEAA in human blood compared to control. However, this extract significantly (p < 0.05) reduced fever in a dose-dependent manner during the antipyretic experiment. Besides, in computer-aided investigations, two compounds (2,4-ditert-butylphenol and 3-hydroxy-β-damascone) revealed the best binding interaction with six proteins for cytotoxicity, inflammation, helminthic, thrombolytic and pyretic effect. Moreover, these two compounds satisfy Lipinski’s ‘Rule of Five’ and revealed drug-likeness profiles in the toxicological study. Conclusions These findings disclosed that methanol leaves extract of A. auriculiformis might be a potent source for anti-inflammatory, anti-helminthic, thrombolytic and antipyretic agents.

Safflower honey is a unique type of monofloral honey collected from the nectar of Carthamus tinctorius L. in the Apis mellifera colonies of northwestern China. Scant information is available regarding its chemical composition and biological activities. Here, for the first time, we investigated this honey’s chemical composition and evaluated its in vitro antioxidant and anti-inflammatory activities. Basic physicochemical parameters of the safflower honey samples in comparison to established quality standards suggested that safflower honeys presented a good level of quality. The in vitro antioxidant tests showed that extract from Carthamus tinctorius L. honey (ECH) effectively scavenged DPPH and ABTS+ free radicals. In lipopolysaccharides (LPS) activated murine macrophages inflammatory model, ECH treatment to the cells inhibited the release of nitric oxide and down-regulated the expressions of inflammatory-relating genes (iNOS, IL-1β, TNF-α and MCP-1). The expressions of the antioxidant genes TXNRD, HO-1, and NQO-1, were significantly boosted in a concentration-dependent manner. ECH decreased the phosphorylation of IκBα and inhibited the nuclear entry of the NF-κB-p65 protein, in LPS-stimulated Raw 264.7 cells, accompany with the increased expressions of Nrf-2 and HO-1, suggesting that ECH achieved the anti-inflammatory effects by inhibiting NF-κB signal transduction and boosting the antioxidant system via activating Nrf-2/HO-1 signaling. These results, taken together, indicated that safflower honey has great potential into developing as a high-quality agriproduct.

AbstractBackground:Our previous studies showed that fruit methanol extract fromMethods:PC-3 and LNCaP cells were cultured and treated with MEXA (10, 50 and 100 μg/mL). The sodium 3′-[1-(phenylaminocarbonyl)-3,4-tetrazolium]-bis (4-methoxy-6-nitro) benzene sulfonic acid hydrate (XTT) and lactate dehydrogenase (LDH) assays were used to evaluate cell viability and cytotoxicity, respectively. DNA fragmentation was determined by cell death detection ELISA plus, and angiogenesis was assessed by chicken chorioallantoic membrane (CAM) assay. The antioxidant activities of MEXA were determined by DPPH and hydroxyl (OH) radicals’ scavenging methods as well as through the inhibition of lipid peroxidation (LPO) in rats’ liver homogenate.Results:MEXA at 100, 250 and 500 μg/mL scavenged DPPH by 48%, 62%, 70% and OH radical by 39%, 58%, 67%, respectively. MEXA significantly (p<0.05) inhibited LPO in a concentration-dependent manner. In addition, MEXA had antiproliferative effects on PC-3 and LNCaP with ICConclusions:These findings suggest that MEXA induces antiproliferative activity in PCa cells through a mechanism that involves apoptosis. Therefore, MEXA may be a potential therapeutic agent for PCa.
