Objective: The study aimed to evaluate the anti-inflammatory activity of Amomum subulatum (greater cardamom) seed and rind extracts in Wistar rats. Methods: The seed and rind of A. subulatum were air-dried in the shade, powdered, and subjected to 80% hydroalcoholic extraction in the Soxhlet apparatus. The anti-inflammatory activity of the seed and rind extracts of A. subulatum was evaluated by in vivo and in vitro methods. Results and Discussion: In vivo studies, namely, carrageenan-induced rat paw edema, cotton pellet granuloma, and formaldehyde-induced arthritis model confirmed the anti-inflammatory potential of seed and rind extracts of A. subulatum. It was found that rind extract exhibited better inhibition of inflammation as compared to seed extract. A. subulatum rind extract at the dose of 500 μg/ml exhibited best results for in vitro studies, namely, inhibition of albumin denaturation (73% inhibition), antiproteinase action (58% inhibition), membrane stabilization, heat-induced hemolysis, hypotonicity-induced hemolysis (54% inhibition), anti-lipoxygenase activity. Conclusions: The results of the study showed that the rind extract of A. subulatum (greater cardamom) possesses significant anti-inflammatory potential in various in vivo and in vitro anti-inflammatory models in the experimental animals.

Legume proteins are precursors of bioactive components, such as peptides. In the present paper, different types of legume as sources of bioactive peptides and hydrolysates are considered and discussed based on their anti-inflammatory effect. Peptides with anti-inflammatory activity were included from in vitro and in vivo studies. Current strategies for obtaining bioactive peptides, as well as their structure and impact on health, were also reviewed. It was discovered that peptides derived from legume protein, mainly soybean and bean, can regulate several inflammatory markers, which include prostaglandin E2 (PGE2), nitric oxide (NO), inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX- 2), cytokines, and chemokines. So far, lunasin, VPY and γ-glutamyl peptides have been identified with anti-inflammatory activity but their mechanisms have not been fully elucidated. Furthermore, it is necessary to gather more information about hydrolysates containing peptides and single peptides with antiinflammatory activity. Considering the wide diversity, legume may be promising components to produce peptides efficient to ameliorate inflammatory disorders.

Objective: Naringenin (NAR) a flavonoid, exhibits extensive pharmacological action, fails to attain a significance in application due to low aqueous solubility (~ 0.214 mg/mL) which results in low bioavailability (5.8%). Nanosuspension of NAR (NARNS) was prepared in our previous studies using high-pressure homogenization employing various polymers. All these formulations were characterized and as a continuation of our work formulations was further evaluated for their anti-inflammatory activity by in vitro and in vivo methods. Methods: Denaturation of protein method and membrane stabilization methods was chosen for in vitro evaluation. In vivo studies performed were acute inflammatory studies (carrageenan-induced paw edema) and chronic inflammatory studies (cotton pellet granuloma) on Wistar albino rats. Results: The studies demonstrated that the NAR and NARNS at a dose of 50mg/kg P.O. have a potent activity compared to the standard drug diclofenac. Conclusion: The percentage of protection against inflammation exhibited by NARNS was highly significant compared to NAR.

Objective: Manilkara zapota is a medicinal plant which is native to Mexico and Central America, and widely distributed in India. Various parts of this plant are traditionally used for treatment of several diseases, including inflammation-associated ailments. The main aim of the present study is to evaluate the anti-inflammatory potential of ethyl acetate and methanolic extracts of M. zapota leaf.Methods: In vitro secretary phospholipase A2 (PLA2) and 5-Lipoxygenase (5-LOX) assays and In vivo studies using carrageenan induced rat paw edema model were performed to assess the anti-inflammatory activity of M. zapota leaf extracts.Results: In vitro studies suggest that M. zapota leaf extracts exhibited significant SPLA2 and 5-LOX inhibitory activities. In in vivo studies M. zapota leaf extracts showed dose dependent inhibition of carrageenan induced paw edema in rats. The anti-inflammatory activity of ethyl acetate leaf extract was superior to methanolic extract.Conclusion: This study concluded that ethyl acetate leaf extract of M. zapotaexhibited significant anti-inflammatory activity and warranted further investigation to isolate and identify the components.

Background: NSAIDS are associated with side effects and research should continue for developing safer drugs. This study aims to evaluate newer thiazolidine-4-ones for their anti-inflammatory and ulcerogenic activities in wister rats.Methods: Five groups of wister rats, 6 in each were used.  Anti-inflammatory and ulcerogenic activities of diclofenac (30mg/kg), nimesulide (50mg/kg), thia-1 (50mg/kg) and thia-2 (50mg/kg) are compared with control group (4% Gum Acacia). Carrageenin-induced paw edema, formaline induced acute peritonitis and cotton pellet-induced granulomatous tissue formation models were used for evaluating anti-inflammatory activity. After removing cotton pellets with granuloma on 8th day gastric ulcerogenicity was assessed by using macroscopic and microscopic scoring of ulcers.Results: Diclofenac, nimesulide and thia 2 reduced both paw edema and peritoneal exudate volume significantly (p <0.01). Wet weight of cotton pellets reduced significantly (p <0.01) by diclofenac, nimesulide and thia 2. Diclofenac (p <0.01) and thia 2 (p <0.05) reduced dry weight of cotton pellets significantly. nimesulide and thia-1 reduced it by 19.14% and 2.68% respectively and was considered statistically not significant (p>0.05). Nimesulide, thia-1 and thia-2 did not increase gastric ulcer score significantly (p >0.05). Diclofenac increased ulcer score significantly (p <0.01).Conclusions: Thia-2 demonstrated significant anti-inflammatory activity in acute and chronic models. In addition to inhibition of cyclooxygenase pathway, PPAR agonistic activity may be involved in its anti-inflammatory activity.  No significant ulcerogenicity was observed on comparing with nimesulide and control. Further in-vitro and in-vivo studies are recommended to confirm the results of this study.

Objective: Dietary curcumin and capsaicin are well known for their health beneficial potencies. The current study was done to assess the anti-inflammatory activity of curcumin, capsaicin and their combination by employing in vitro and in vivo models.Methods: We investigated the protective effect of curcumin, capsaicin and their combination using in vitro heat induced human red blood cell (HRBC) membrane stabilisation, in vivo 3% agar induced leukocyte mobilisation and acetic acid induced vascular permeability assay.Results: Curcumin, capsaicin and their combination exhibited concentration dependent protective effect against heat-induced HRBC membrane destabilisation, while combined curcumin and capsaicin restored 87.0±0.64 % membrane stability and it is found to be better than curcumin, capsaicin and diclofenac sodium (75.0±0.25. 72±0.9 and 80.0±0.31 %) protective effect. In agar suspension induced leukocyte mobilization assay, the combined curcumin and capsaicin had shown 39.5±1.58 % of inhibition compared to individual curcumin and capsaicin, which showed moderate inhibition of 16.0±3.14 and 21.6±2.17 % respectively. Besides, the combined curcumin and capsaicin had shown highly significant inhibition of acetic acid-induced vascular permeability in rats (62.0±3.14 %), whereas individual curcumin and capsaicin showed moderate inhibition of vascular permeability with 36.0±2.41 and 43.0±1.92 % respectively.Conclusion: This study demonstrates the significant anti-inflammatory property of combined curcumin and capsaicin at half of the individual concentration of curcumin and capsaicin.
