Alchornea cordifolia (Schum and Thonn) Muell. Arg. (Euphorbiaceae) is a traditional medicinal plant widely distributed in West Africa including Nigeria.The plant has been used for ethnomedicinal purposes against wounds, ulcers, and sores. The decoction of the leaves has been reported to provide remedies for bronchial problems, rheumatic pain and cough. From the dichloromethane and ethyl acetate soluble parts of the Methanol leaf extract, two compounds namely Lup-20(29)-en-3c-ol (lupenol) and Methyl 3, 4,5-trihydroxy benzoate (Methyl gallate) were isolated and their structures elucidated. Anti-inflammatory and analgesic properties of the compounds on carrageenan-induced paw oedema and formalin-induced pain in rats showed that compound 2 significantly (P<0.05) inhibit rat paw oedema compared to the standard drugs (Piroxicam and Morphine) used, while on formalin-induced pain in rats, the same trend was observed and were both comparable to Piroxicam and morphine, the standard anti-inflammatory and analgesic agents used, respectively. Compound 1 did not show any significant anti-inflammatory activity compared to control, likewise compound 2. Thus, compound 2, Methyl trihydroxy benzoate, might be responsible for the anti-inflammatory and analgesic properties of this plant.Keywords: Alchornea cordifolia, Anti-inflammatory, Analgesic, Methyl Trihydroxy Benzoate

Combretum glutinosum Perr. Ex DC (COMBRETACEAE) is a traditional medicinal plant, widely distributed in Senegal and Africa. The aim of that study was to investigate the analgesic and anti-inflammatory activities of two triterpenes, betulonic acid (DN7) and cabraleone (DN12), isolated from the leaves of Combretum glutinosum. Experiments were performed in acetic acid-induced contortions in mice and carrageenan rat paw oedema. DN7 (3 mg/kg, per os) and DN12 (3 mg/kg, per os) significantly prevent contortions in mice. The number of contortions is respectively 30±10 and 32±7 versus 72.6±6.64 in control group (p<0.05, n=5). DN7 (3 mg/kg, per os) significantly prevented the increased rat paw oedema (31.84±6.76 vs 92.72±6.05%) (p<0.05, n=5). DN12 (10 mg/kg, per os) induced rat paw oedema prevention similar to that of acetylsalicylic acid (10 mg/kg, per os) administered in the same conditions (29.28±5.88 vs 30.96±7.25%; ns, n=5). The analgesic and anti-inflammatory activities of triterpenes isolated from C. glutinosum leaves are similar to those of non-steroidal anti-inflammatory drugs such acetylsalicylic acid, justifying the use of this plant in traditional medicine to manage pain and inflammation.

The folkloric use of Clerodendrum volubile P Beauv (Verbenaceae) for treatment of inflammatory conditions in the Southern part of Nigeria has been reported. The anti-inflammatory action of the ethanolic leaf extract on carrageenan-induced rat paw oedema, lipoxygenase and xanthine oxidase inhibitory effects, and membrane stabilizing potential were evaluated. The extract reduced carrageenan-induced rat paw oedema in a dose dependent manner compared to control group. C. volubile inhibited xanthine oxidase activity in a dose - dependent manner; at 0.5 mg/ml it exhibited maximum inhibitory activity of 95.48% while the standard drug, allopurinol exhibited 70 % inhibition. The extract significantly inhibited lipoxygenase activity, with highest activity at 0.4 mg/ml while Quercetin showed maximum inhibition of the enzyme at 0.1 mg/ml. The extract and Acetaminophen exhibited maximum membrane stabilizing activity of 91.85 ± 0.50% and 94.32 ± 0.32% at 2.5 mg/ml respectively. These findings provide justification for the traditional use of C. volubile in inflammatory conditions.

Background: Lichens which are betide to mangroves are termed as Manglicolous Lichens (ML). As these ML are habituated under stress conditions, they are screened for unique metabolites and biological activities. Objective: The study aimed to establish the chemical and biological profile of ML, Graphis ajarekarii. Methods: The Ethyl Acetate Extract of G. ajarekarii (EAE) was subjected to chromatographic techniques and the obtained isolates were characterized by spectroscopic analysis. The hydroalcoholic extract of G. ajarekarii (AE), EAE, isolates and Hydroalcoholic Extract of host (HE) were evaluated for fibrinolytic (fibrin clot method), in vitro (protein denaturation method) and in vivo (formalin-induced rat paw oedema assay), anti-inflammatory and cytotoxicity (MTT assay) activities. Results: Chemical investigation of the EAE led to the isolation of two known compounds namely atranorin (1) and ribenone (2), which were confirmed by spectral data. The AE and EAE gradually lysed the fibrin clot with 94.54 and 65.07%, respectively, at 24 h. The AE inhibited protein denaturation of about 88.06%, while the standard (Indomethacin) with 93.62%. Similarly, the in vivo antiinflammatory analysis of AE (200 mg/mL) showed potent reduction of rat paw oedema than the standard, whereas EAE and 1 depicted moderate depletion. In addition, the AE revealed prominence inhibition on MCF-7, DU145 and K-562 with IC50 values of 69.5, 42.5 and 38 µg/mL, respectively, whereas the HE exhibited mild inhibitory profile against fibrin clot, inflammation and cancer. Conclusion: From the results, it can be concluded that the G. ajarekarii has an aptitude to act against coagulation, inflammation and cancer cells.

A re-investigation of the methanolic extract of the aerial parts of Tanacetum santolinoides has resulted in the isolation of a new sesquiterpene, tanacetonic acid (1), along with three known methoxylated flavonoids. The structure of the isolated compounds was secured based on their IR, UV, 1D and 2D (1H-1H COSY, HSQC and HMBC) NMR spectroscopic and FAB mass spectral characteristics. The new sesquiterpene showed a significant cytotoxic activity when tested using the brine shrimp bioassay, while the three flavonoids demonstrated anti-inflammatory effects in the rat paw oedema test.

Context. Pleurotus ostreatus (P.o) is a culinary mushroom which is commonly called as “oyster mushroom” belonging to the Basidiomycetous fungi of the order Agaricales and family Pleurotaceae. Objectives. The present study investigates the anti-inflammatory potential of P.o and the underlying mechanisms of activity. Materials and Methods. Anti-inflammatory activity was evaluated using suspensions of freeze-dried and powdered (SFDP) P.o and acetone extract (AE) of P.o in normal and alloxan-induced diabetic rats using the carrageenan-induced rat paw oedema model. The mechanisms by which P.o is mediating the anti-inflammatory activity were studied using in vivo and in vitro assays. Results. At doses of 500–1000 mg/kg, the SFDP of P.o showed long-lasting activity at both early and late phases of carrageenan-induced rat paw oedema. The dose of 750 mg/kg showed the most potent inhibitory activity (92% inhibition) in healthy rats. The AE of P.o showed maximum inhibition of oedema of 87%. P.o exerted protective effects on the inflammatory pathologies in rats with diabetes. The possible mechanisms by which P.o mediates the anti-inflammatory activity were antihistamine activity (52.1%), inhibition of cell migration to the site of inflammation (45.4%), in vitro membrane stabilizing activity (52.6%), and inhibition of nitric oxide (NO) production (91.2%) (P<0.05). Dose-dependent inhibition of NO production was seen with in vitro treatment of rat peritoneal cells with AE of P.o (r = 0.95; P<0.05). Discussion and Conclusion. The promising activity of culinary mushroom P.o against inflammation suggests its potential application as a functional food during inflammatory conditions.

New pyranocoumarin and coumarin-sulfonamide derivatives were prepared and evaluated for their antioxidant, antimicrobial, and/or anti-inflammatory activities. Coumarin-sulfonamide compounds 8a–d demonstrated significant antioxidant activity, while 7c,d, 8c,d, and 9c,d exhibited antimicrobial activity equal to or higher than the standard antimicrobials against at least one tested microorganism. Regarding the anti-inflammatory testing, pyranocoumarins 2b, 3a,b and 5c and coumarin-sulfonamide compound 9a showed more potent antiproteinase activity than aspirin in vitro; however, five compounds were as potent as aspirin. The anti-inflammatory activity of the promising compounds was further assessed pharmacologically on formaldehyde-induced rat paw oedema and showed significant inhibition of oedema. For in vitro COX-inhibitory activity of coumarin derivatives, pyranocoumarin derivative 5a was the most selective (SI = 152) and coumarin-sulfonamide derivative 8d was most active toward COX-2 isozyme. The most active derivatives met the in silico criteria for orally active drugs; thus, they may serve as promising candidates to develop more potent and highly efficient antioxidant, antimicrobial, and/or anti-inflammatory agents.

The various extracts ofMerremia tridentatewere investigated for its anti-inflammatory and anti-arthritic activities in male albino rats. The anti-inflammatory activity was carried out using carrageenan-induced rat paw oedema model and the anti-arthritic activity was carried out using complete Freund’s adjuvant induced arthritis model. Indomethacin (10 mg/kg bw) was used as a standard drug. The ethanol extract ofM. tridentateexhibited significant dose dependent activity in acute inflammation and the doses of 100 mg/kg bw and 200 mg/kg bw produced 38.3% and 42.8% inhibition respectively after 3 h as compared with that of the standard drug which showed 48.5% inhibition. In arthritis model, the doses of 100 mg/kg bw and 200 mg/kg bw of the ethanol extract produced 49.0% and 51.7% inhibition respectively after 19 days when compared with that of the standard drug (55.5%). Both doses of the ethanol extract ofM. tridentateexhibit significant anti-inflammatory and anti-arthritic activities.
