Background: Plants have several chemical compounds acclaimed to be responsible for the pharmacological actions produced when herbal products are administered to biological systems.Objectives: This study was designed to investigate the anti-inflammatory effect of the alkaloid-rich fraction of the ethanol leaf extract of Landolphia owariensis.Methods: Qualitative phytochemical analyses were carried on the crude extract using standard methods. The alkaloid-rich fraction was obtained from the crude ethanol extract, using the classical acid/base shake-up method and the obtained fraction tested positive to Dragendorf’s reagent. Oral acute toxicity was evaluated by OECD method (No 423). Anti-inflammatory effect of the fraction was evaluated using xylene-induce ear oedema and carrageenan-induced paw inflammation in mice at doses of 100, 200 and 400 mg/kg.Results: Phytochemical screening revealed presence of alkaloids, flavonoids, tannins, saponins, steroids/terpenes and glycosides. Acute toxicity studies showed no adverse symptoms of toxicity during the 14-day observation period and no mortality was recorded, thus the LD50 was estimated to be greater than 2000 mg/kg. The alkaloid-rich fraction dose-dependently inhibited inflammation induced by xylene and carrageenan. In the xylene test, the fraction produced significant inhibition of 41.70 % at 400 mg/kg (p ≤ 0.05) while in the carrageenan test 55.69 % significant inhibition (p ≤ 0.001) was recorded with 400 mg/kg at 60 mins after induction of inflammation.Conclusion: This study showed the anti-inflammatory potentials of the alkaloid-rich fraction of Landophia owariensis.

Background: The decoction of the roots of Salacia lehmbachi is used in traditional medicine for the treatment different diseases such as malaria pains diabetes and microbial infections.Methods: Phytochemical screening and oral acute toxicity tests were carried out on the ethanol root extract of the plant. Anti-nocicetive activity using acetic acid induced writhing and tail immersion method in mice, anti-inflammatory activity using carrageenan induced paw oedema in rats and xylene induced ear oedema test in mice and antipyretic activity using Brewer’s yeast and D-amphetamine induced pyrexia in rats were determined at 50 mg/kg, 100 mg/kg and 200 mg/kg doses of the root extract.Results: The ethanol root extract contain alkaloids, saponins, tannins, flavonoids, terpenoids, steroids and cardiac glycosides. The oral acute toxicity tests was found to be greater than 5000 mg/kg. The root extract and the standard drug (Aspirin) significantly (p<0.05 and p<0.01) decreased the number of writhes caused by acetic acid. The extract and morphine significantly (p<0.05 and p<0.01) prolonged reaction time in tail immersion model. The extract produced significant (p<0.05 and p<0.01) dose dependent inhibition of oedema which was comparable to aspirin in carrageenan induced paw oedema model. The root extract also demonstrated significant (p<0.05 and p<0.01) effect in xylene induced mouse ear oedema test compared to dexamethasone. The extract significantly decreased high temperature in both Brewer’s yeast and d-amphetamine induced pyrexia.Conclusions: Findings show that S. lehmbachii may provide a good source of plant compounds with analgesic, anti-inflammatory and antipyretic activities.

Dipterocarpus tuberculatus Roxb. has been used traditionally as a remedy for many diseases, especially inflammation. Therefore, we analyzed and explored the mechanism of the anti-inflammatory effect of a Dipterocarpus tuberculatus Roxb. ethanol extract (Dt-EE). Dt-EE clearly and dose-dependently inhibited the expression of pro-inflammatory cytokines such as IL-6, TNF-α, and IL-1β in lipopolysaccharide (LPS)-treated RAW264.7 cells. Also, Dt-EE suppressed the activation of the MyD88/TRIF-mediated AP-1 pathway and the AP-1 pathway related proteins JNK2, MKK4/7, and TAK1, which occurred as a result of inhibiting the kinase activity of IRAK1 and IRAK4, the most upstream factors of the AP-1 pathway. Finally, Dt-EE displayed hepatoprotective activity in a mouse model of hepatitis induced with LPS/D-galactosamine (D-GalN) through decreasing the serum levels of alanine aminotransferase and suppressing the activation of JNK and IRAK1. Therefore, our results strongly suggest that Dt-EE could be a candidate anti-inflammatory herbal medicine with IRAK1/AP-1 inhibitory and hepatoprotective properties.

ABSTRACT The present study was designed to investigate the antioxidant, antinociceptive and anti-inflammatory activities of the ethanol extract from Ageratum fastigiatum branches. Phytochemical screening and total phenol and flavonoid contents were determined. The antioxidant activity was assessed by 2,2-diphenyl-1-pycrilhydrazin (DPPH) and iron reducing power methods. The antinociceptive effect was evaluated using the acetic acid-induced writhing, formalin, hot plate and tail immersion assays; while the carrageenan-induced paw edema and pleurisy tests were performed to examine the anti-inflammatory activity against acute inflammation. The extract revealed the presence of flavonoids, tannins, coumarins, terpenes, sterols and saponins. Expressive levels of total phenols and flavonoids and a promising antioxidant effect were quantified. At the doses of 50, 100 and 200 mg/kg, the extract inhibited the writhing, reduced both phases of paw licking time and increased the reaction time on the hot plate. In the tail immersion test, the extract (50, 100 and 200 mg/kg) caused a significant inhibition of pain. In these doses, the paw edema, exudate volume and leucocyte mobilization were significantly reduced. These results suggest that A. fastigiatum can be an active source of substances with antioxidant, antinociceptive and anti-inflammatory activities, adding scientific support to the appropriate use in the Brazilian folk medicine.

Caralluma is a plant that possessing a great therapeutic potential in folk medicine in Yemen, namely, Caralluma penicillata (C. penicillata) as antiulcer. The study aims to evaluate the anti-inflammatory properties and gastritis protection activity of C. penicillata against indomethacin in adult guinea pigs. The study was divided into four parts: firstly, the optimum dose of extract as anti-inflammatory effect was determined. Secondly, the acute anti-inflammatory effect of extract were estimated. Thirdly, the repeated doses of extract against chronic inflammation was estimated. The anti-inflammatory activity of extract was compared with indomethacin as a prototype of drug against inflammation. Fourthly, the gastritis protection properties of extract with/without indomethacin were performed. The results showed that a 400 mg/kg of 10% ethanol extract produced the maximum of anti-inflammatory effect. Also, the single dose of extract was equipotent for indomethacin (10 mg/kg), but shorter in duration with regard to acute anti-inflammatory effect. In addition, the repeated doses of extract against chronic inflammation were less potent than indomethacin with regard to ulcerogenic effect. On the other hand, extract-indomethacin combination reduced the gastritis effect of indomethacin based on ulcer index and histological study.

We investigated the antioxidant and anti-inflammatory effects of a 70% v/v ethanol extract of the stem bark of Antrocaryon micraster on murine models of carrageenan-induced pleurisy and paw oedema. Rat pleural fluid was analysed for volume, protein content, and leucocytes, while lung histology was assessed for damage. Lung tissue homogenates were assayed for glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and myeloperoxidase (MPO). Phytochemical analysis was carried out on the stem bark. Acute toxicity studies were conducted in rats. In the pleurisy model the extract (30–300 mg/kg) significantly reduced the volume and amount of proteins and leucocytes in the exudate and also protected against lung injury. Tissue level of GSH and SOD and CAT expression were increased while MDA level and MPO activity were reduced. The peak and total oedema responses were significantly suppressed when given both preemptively and curatively in the mice paw oedema test. Saponins, alkaloids, triterpenoids, and tannins were present in the stem bark. A. micraster extract exhibited no apparent acute toxicity. We conclude that the ethanolic stem-bark extract of A. micraster has antioxidant action and exhibits significant anti-inflammatory activity through suppression of pleurisy and paw oedema induced with carrageenan.
