Objective: The aim of the present study was to evaluate anti-inflammatory activity of methanolic extract of Terminalia coriacea. Materials and Methods: A methanolic extract of T. coriacea leaves was studied in albino Wistar rats with carrageenan-induced paw edema, an acute model, and cotton pellet-induced granuloma, a chronic model, at 3 oral test doses (125, 250, and 500 mg/kg). Aspirin 100 mg/kg was used as a positive control. Paw volume and wet and dry weights of cotton pellets were determined. The data were analyzed by one-way ANOVA followed by Dunnett’s multiple comparison test. Results: The test extract at doses of 125 and 250 mg/kg decreased paw volume and wet and dry weights of cotton pellets. The highest test dose (500 mg/kg) displayed a response comparable to that of the standard drug (p < 0.01) on paw volume. The extract produced similar (p < 0.05) decrease in wet weight of the cotton pellet at 125 and 250 mg/kg, whereas the effect of 500 mg/kg of the extract was comparable to that of aspirin 100 mg/kg (p < 0.01). The extract of T. coriacea at 500 mg/kg induced the most significant (p < 0.01) effect on wet weight of granulomatous tissue. Conclusion: The methanolic extract of T. coriacea leaves successfully decreased paw edema as well as dry and wet weights of granulomatous tissue in both acute and chronic inflammatory models thus confirming the anti- edematogenic, antitransudative, and antiproliferative properties of T. coriacea.

Abstract. Belay R, Makonnen E. 2018. Anti-inflammatory activities of ethanol leaves extract and solvent fractions of Zehneria scabra (Cucurbitaceae) in rodents. Biofarmasi J Nat Prod Biochem 18: 42-56. Zehneria scarba (L.f.) Sond is one of the medicinal plants used in folkloric medicine of Ethiopia for years to treat various inflammatory disorders. The present study was aimed to validate the anti-inflammatory activity of crude 70% ethanol leaves extract (70EE) against a sub-acute model and further evaluate the solvent fractions (AF, BF, and CF) in an acute (carrageenan-induced paw edema), sub-acute (formaldehyde induced arthritis) and chronic (cotton pellet induced granuloma) inflammatory models. The 70EE was first prepared by maceration, and the fractions were obtained by sequential partitioning with chloroform and n-butanol from the aqueous suspension of crude 70EE. The test groups, then, received 100, 200 and 400 mg/kg of the crude 70EE or the fractions (AF, BF, and CF) at the same dose levels, whereas positive controls received aspirin (200mg/kg) or dexamethasone (0.5mg/kg) and negative controls received vehicle (2% tween 80 or distilled water, 10 mL/kg). All tested doses of the crude 70EE showed significant inhibition of formaldehyde induced arthritis at the 10th day of treatment, on which the 400mg/kg dose showed the maximum anti-arthritic effect (%A = 60.5; p < 0.001). In the carrageenan-induced paw edema, all the three fractions showed a statistically significant effect, in fact, with different onset and magnitude. In this model, the AF was found to be the most active fraction, and the 400mg/kg dose demonstrated the maximum effect (%A = 76.25; p < 0.001) at 5h post-induction, which is much better than the effect of aspirin at the dose employed. The overall order of efficacy in inhibiting the exudative component of carrageenan-induced paw edema was found to be AF> BF> CF. The AF was also found to be the most active fraction in inhibiting the exudative component of chronic inflammation in the cotton pellet induced granuloma model, where the maximum effect (%A = 43.10, p < 0.001) was exhibited by a dose of 400mg/kg. The AF was also the most active fraction in inhibiting formaldehyde induced arthritis, in which the BF and CF relatively showed a comparable effect throughout day 4-10. On the contrary, in the cotton pellet induced granuloma model, the CF was found to be the most active fraction in inhibiting the proliferative and granulomatous component of chronic inflammation, and the overall order of effectiveness was found to be CF> AF> BF. Besides, 400mg/kg of CF demonstrated the maximum inhibition of granuloma formation (%A = 55.52; P < 0.001). The phytochemical analysis revealed the differential distribution of secondary metabolites into the three fractions, which either singly or in concert appeared to be responsible for the observed effects. The data obtained from the present study collectively indicate that the extract and fractions of leaves of Z.scabra possessed a significant anti-inflammatory activity, upholding the folkloric use of the plant.

Introduction: Guazuma ulmifolia (Sterculiaceae) is commonly used in folk medicine as a single drug remedy to treat various ailments like; skin diseases, headache, wounds, ulcers, asthma, kidney disease and malaria. However, the use of the herb for treatment of pain and inflammation has not been scientifically investigated. Objective: This study of 80% methanolic crude extract of the leaves of Guazuma ulmifolia was evaluated for its analgesic and anti-inflammatory properties using established animal models. Material and methods: Wister albino rats were randomly divided into four groups of six rats per group. The control group was orally given 2 ml/kg (p.o.) of distilled water. The positive control received standard drug (Diclofenac 10 mg//kg, Indomethacin 20 mg/kg). The rest of the groups were treated with 80% methanolic extract of Guazuma ulmifolia at doses of 250 and 500 mg/kg. Animals were then subjected to tests using hot plate and tail-clip for analgesic activity, for anti-inflammatory activity carrageenan-induced paw edema test and histamine-induced paw edema test was used. Result and Discussion: Guazuma ulmifolia extract showed a dose-dependent significant reduction of pain in analgesia models (p<0.001) with 500 mg/kg dose producing the highest reduction. The extract significantly reduced carrageenan-induced inflammation in a dose-independent manner, in which the highest reduction of inflammation was observed at 500 mg/kg. Conclusion: The data collectively indicate that 80% methanolic extract of Guazuma ulmifolia leaves has potential analgesic and anti-inflammatory activities.

Background: Inflammation is a complex reaction to various injurious agents such as infections, trauma, foreign bodies, tissue necrosis, physical and chemical agents, that consists of vascular responses, migration and activation of leukocytes and systemic reactions. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) are currently the most commonly prescribed drugs for treating pain and inflammation. The traditional NSAIDs usually cause various adverse effects on long term use. Gmelina arborea Linn (Gambhari) belongs to family Verbenaceae. The roots, leaves, flowers, fruits and bark are used for treating different ailments as anthelmintic, analgesic, anti-pyretic, antidiabetic, antimicrobial, diuretic and other common disorders.Methods: The study was carried out by using inflammatory models in wistar rats. The anti-inflammatory activity of G. arborea was compared with standard drug aspirin. The study parameters for acute inflammation was assessment of reduction in inflammation & the percentage inhibition of the paw edema. The parameter for the sub-acute inflammation was percentage inhibition of the dry granuloma weight.Results: The low and high dose of G. arborea root extract significantly showed the anti-inflammatory activity when compared to control group. The high dose of G. arborea extract showed comparable results in parameters like reducing inflammation, percentage inhibition of paw edema and dry granuloma weight in acute carrageenan paw edema and sub-acute inflammation cotton pellet granuloma models with standard aspirin treated group.Conclusions: Since G. arborea root extract was having all the qualities required for anti-inflammatory drug. However, no clear inference can be drawn at this stage and hence we consider the work for further extensive research.

Nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely used for the treatment of inflammation. However, despite their effectiveness, most NSAIDs cause various side effects that negatively affect the management of inflammation and, in part, pain. Thus, there is a need to search for new anti-inflammatory agents with few, or no, side effects. Natural products of plant, animal, or microorganism origin have been good sources of new bioactive compounds. The present study was carried out to evaluate the acute and chronic anti-inflammatory activities of the essential oil of the rhizomes of Zingiber zerumbet (Zingiberaceae) using the carrageenan-induced paw edema and cotton pellet-induced granuloma tests, respectively. The effect of the essential oil on inflammatory- and noninflammatory-mediated pain was also assessed using the formalin test. Essential oil of Z. zerumbet, at doses of 30, 100, and 300 mg/kg, was administered intraperitoneally to rats. The substance exhibited significant anti-inflammatory activity both in acute and chronic animal models. The essential oil also inhibited inflammatory- and noninflammatory-mediated pain when assessed using the formalin test. In conclusion, the essential oil of Z. zerumbet possessed anti-inflammatory activity, in addition to its antinociceptive activity, which may explain its traditional uses to treat inflammatory-related ailments.

Abstract: Rubiadin is identified as a bioactive anthraquinone that exists in some quinone rich plants. The current research was carried out to evaluate the potential anti-inflammatory impact of Rubiadin in acute and chronic inflammation test models in rodents. The anti-inflammatory activity of Rubiadin was examined in cotton pellet-induced granuloma and carrageenan-induced edema as chronic and acute inflammation models in rats. TNF-α level and histopathological changes were assessed using sampled foot tissue of rat in the acute model. Also, the IL-1β level was assessed in the chronic model. One-way ANOVA (post hoc Tukey’s) analysis was used for comparing the groups. Rubiadin (0.5 mg/kg, i.p.) induced a significant reduction in TNF α level and the paw edema compared to the control group in carrageenan test. Also, it was observed that the anti-inflammatory activity of Rubiadin (0.5 mg/kg, i.p.) is comparable to mefenamic acid (30 mg/kg, i.p.) as the standard drug. Rubiadin was effective in granuloma induced by cotton pellet concerning the granuloma and transudate formation amount. Rubiadin’s anti-inflammatory effects were associated with a significant IL-1β decrease in this model. The results suggest that Rubiadin as a natural compound can possess significant peripheral anti-inflammatory impacts.
