Analgesic and anti—inflammatory activities of the ethanol extract of the leaves of Helianthus Annus in Wistar rats

ObjectiveTo investigate the anti-inflammatory and analgesic effects of the ethanol extract of leaves of Helianthus annus L. (H. annus) in acclimatized Wistar rats.MethodsIt was undertaken using the albumin induced paw edema model of inflammation as well as both the hotplate and tail immersion analgesic test methods. Doses of the extract tested in experimental rats were 0.5 g/kg, 2 g/kg and 4 g/kg while negative and positive control rats received distilled water and indomethacin respectively.ResultsIt was shown that treatment with the tested doses of the extract effectively inhibited paw edema induced by egg albumin. This effect was comparable if not better than the observations made in rats treated with 10 mg/kg of indomethacin orally. Treatment with the extract was also observed to have significantly increased the mean tolerance time of rats to thermal noxious stimuli compared to control animals that had distilled water and appeared to be more effective than 10 mg/kg of indomethacin treatment.ConclusionsThese observations confirmed the presence of a strong anti-inflammatory and anti-noiciceptive activity in the ethanol extract of the leaves of H. annus and therefore validated the folkloric use of the leaves of this plant in treatment of pro-inflammatory, post traumatic situations.     

Pharmacological properties and related constituents of stem bark of Pterocarpus erinaceus Poir. (Fabaceae)

ObjectiveTo screen methanol and dichloromethane extracts of stem bark of Pterocarpus erinaceus for anti-inflammatory, analgesic, in vitro antioxidant activities and phytochemical analysis.MethodsAnti-inflammatory activity was determined by using carrageenan induced-edema of mice paw and croton oil-induced edema of mice ear; analgesic effect was evaluated using acetic acid-induced writhing. Phytochemical screening of extracts was performed by thin layer chromatography. The chromatographic fractionation led to the isolation of main active components as friedelin, lupeol and epicathechin. The structures were established by TLC and nuclear magnetic resonance studies.ResultsBoth methanol and dichloromethane extracts, friedelin, lupeol and epicatechin showed a significant anti-inflammatory effect using croton oil induced-ear edema. Furthermore, the action of dichloromethane extract was more important. At the doses of 100 and 200 mg/kg, the methanol extract was able to reduce the carrageenan induced-hind paw edema, while at the doses of 100, 200 and 400 mg/kg, it showed an important analgesic effect against writhing induced by acetic acid injection of 38.8%, 68.0% and 74.3%, respectively. Antioxidative properties of methanol extract and its dichloromethane and ethyl acetate fractions were assessed by using the 1,1-diphenyl-2-picrylhydrazyl method. The methanol extract showed the stronger radical scavenging activity than dichloromethane and ethyl acetate fractions, with an antiradical power of 5, 3.5 and 2 respectively. The main components isolated from these extracts as friedelin, lupeol and epicathechin were responsible of these activities.ConclusionsThe results suggest that the stem bark extracts of Pterocarpus erinaceus possessed important anti-inflammatory, analgesic activities and strong antioxidant properties, therefore, they could be used as natural potential ingredients for pharma ceutical industry.     

Analgesic and anti-inflammatory activities of Piper nigrum L.

ObjectiveTo evaluate and compare the analgesic and anti-inflammatory activity of pure compound, piperine along with hexane and ethanol extracts of Piper nigrum L. fruit in mice and rats.MethodsThe analgesic activity was determined by tail immersion method, analgesy-meter, hot plate and acetic acid induced writhing test. While the anti-inflammatory activity was evaluated by carrageenan-induced paw inflammation in rats.ResultsPiperine at a dose of 5 mg/kg and ethanol extract at a dose of 15 mg/kg after 120 min and hexane extract at a dose of 10 mg/kg after 60 min exhibited significant (P<0.05) analgesic activity by tail immersion method, in comparison to ethanol extract at a dose of 10 mg/kg using analgesy-meter in rats. However, with hotplate method, piperine produced significant (P<0.05) analgesic activity at lower doses (5 and 10 mg/kg) after 120 min. A similar analgesic activity was noted with hexane extract at 15 mg/kg. However, in writhing test, ethanol extract significantly (P<0.05) stopped the number of writhes at a dose of 15 mg/kg, while piperine at a dose of 10 mg/kg completely terminated the writhes in mice. In the evaluation of anti-inflammatory effect using plethysmometer, piperine at doses of 10 and 15 mg/kg started producing anti-inflammatory effect after 30 min, which lasted till 60 min, whereas hexane and ethanol extracts also produced a similar activity at a slightly low dose (10 mg/kg) but lasted for 120 min.ConclusionsIt is concluded from the present study that Piper nigrum L possesses potent analgesic and anti-inflammatory activities.
