Pharmacological properties of Visnea mocanera L. f. extracts: Screening for analgesic,antipyretic, antiinflammatory and ulcerogenic activities in rodents

Different extracts of Visnea mocanera L. f. (Theaceae) were evaluated for analgesic, antipyretic, antiinflammatory and ulcerogenic properties in mice and rats. The acetone extract from the leaves and the syrup from the fruits exerted central analgesic properties, associated with significant but transient antiinflammatory effects on acute inflammatory processes. The acetone extract also possessed topical antiinflammatory effects. The extracts assayed did not display antipyretic and ulcerogenic activity. Sub-acute toxicological experiments indicated a very low toxicity in mice.     

Antipyretic and analgesic studies of the ethanalic extract of Teclea nobilis delile

The crude ethanol extract of the leaves of an African medicinal plant Teclea nobilis has been studied for its antipyretic, analgesic and anti-inflammatory activities.

Pharmacological activities of extracts of Daniellia oliveri (Rolfe) Hutch. and Dalz. (Leguminosae)

Extracts of the stem bark of Daniellia oliveri using hexane, ethyl acetate and methanol were tested for analgesic, antipyretic and antiinflammatory activities. The hexane extract exhibited a dose related analgesic activity whilst the methanolic extract was active in the induced inflammatory condition. The ethyl acetate extract was relatively inactive and none of the extracts showed any antipyretic activity. Metabolic cage studies showed that a 70% ethanolic extract of the bark caused significant decreases in body weight, food intake, urine and stool output of rats. This extract also exhibited a competitive antagonism on histamine-induced contractions of the guinea-pig ileum and a non-competitive inhibition of acetyl choline-induced contraction of the frog rectus abdominis muscle.     

Analgesic and antipyretic properties of Euphorbia royleana latex

The ethyl acetate fraction (EA) from the residue of an 85% ethanol extract of the latex of Euphorbia royleana (Euphorbiaceae) was investigated for antipyretic and analgesic properties. The results showed a dose related peripheral analgesic effect. The fraction assayed exhibited a significant antipyretic effect in hyperthermic rats and rabbits. The oral LD₅₀ was more than 2 g/kg in rats and mice. © 1997 John Wiley & Sons, Ltd.

Pharmacological and toxicological investigations on Foeniculum vulgare dried fruit extract in experimental animals

The ethanol extract of the dried ripe fruit of Foeniculum vulgare (500 mg/kg) was tested for diuretic, analgesic, antipyretic, antimicrobial, cytotoxic activities and its effect on bile secretion in rats. Also, the acute toxicity after 0.5, 1 and 3 g/kg was investigated in mice. The extract showed diuretic, analgesic, antipyretic activities and it enhanced bile secretion. As an antimicrobial agent, the extract inhibited the growth of Staphylococcus aureus and Bacillus subtilis and showed a marked mitodepressive effect. At a dose of 3 g/kg, it caused piloerection and it depressed locomotor activity but caused no deaths when administered acutely to mice.

Antinociceptive and antipyretic activities of the Zizyphus oxyphylla Edgew. leaves

A methanol extract of Zizyphus oxyphylla Edgew leaves has been investigated for its analgesic and antipyretic activities in Adult Wistar and Swiss albino mice of either sex at 50, 100 and 200 mg/kg orally. The extract demonstrated marked antipyretic activity against Brewer's yeast-induced pyrexia in rats. The extract demonstrated significant peripheral analgesic effect in the acetic acid-induced writhing test in mice. The phytochemical tests revealed that the extract contained alkaloids, anthraquinones, flavonoids, glycosides, phenols, resins, saponins and tannins using standard procedures. In conclusion, the present study suggests that the methanol extract of Zizyphus oxyphylla Edgew leaves possesses potent antipyretic and antinociceptive activities and thus validates its use in the treatment of pain and fever.     

Analgesic,antipyretic and antiinflammatory effects of Achillea ageratum

The aqueous and methanol extracts of Achillea ageratum L. (Asteraceae) have been evaluated for analgesic, antipyretic and antiinflammatory properties in mice and rats in several experimental models. The aqueous extract exhibited significant activity in the analgesic and antiinflammatory assays but was unable to reduce hyperthermia. Moreover, the methanol extract exerted effects in three pharmacological actions. The phytochemical investigation of this latter extract revealed the presence of flavonic compounds: luteolin, quercetin and 7-O-β-luteolin. © 1997 John Wiley & Sons, Ltd.     

A Study of Some Pharmacodynamic Actions of Certain Melaleuca Species Grown in Egypt

Some pharmacological actions of ethanol extracts of M. elliptica, M. bracteata, M. quinquenervia and M. styphelioides as well as the volatile oil of M. elliptica were experimentally investigated. The ethanol extracts of the plants were nontoxic (LD₅₀ are 102.5, 260.0, 147.5 and 168.0 mg/kg b.wt, respectively). The extracts inhibited spontaneous contraction of smooth muscle of isolated rabbit intestine and rat uterus. They produced myocardial inhibition and decreased the motility of Taenia worms. Ethanol extracts of M. elliptica, M. bracteata, M. quinquenervia and M. styphelioides had no antipyretic, antiinflammatory or molluscicidal activities, whereas the ethanol extract of M. styhphelioides had an analgesic effect in mice. The volatile oil of M. elliptica inhibited the intestinal motility but stimulated the myocardial contractions of rabbits. It had analgesic, molluscicidal and antimicrobial activities, but lacked both antipyretic and antiinflammatory effects.     

栽培苦参与野生苦参的药效学研究

目的:比较栽培与野生苦参的清热、利尿、镇痛方面的药效学作用。方法:以干酵母致大鼠高热模型比较栽培苦参与野生苦参的解热作用;以代谢笼收集大鼠不同时间点的排尿量和总尿量比较栽培与野生苦参的利尿效果;采用热板和扭体法比较观察其对小鼠的镇痛作用。结果:栽培与野生苦参(1,2,4 g.kg-1剂量)均能明显降低酵母菌致热模型大鼠的体温;明显增加大鼠不同时间段的排尿量和排尿总量;栽培与野生苦参3,6 g.kg-1剂量均可明显提高小鼠的热板痛阈值、明显延长小鼠出现扭体的潜伏期并明显减少小鼠的扭体次数,表明其具有非常明显的镇痛作用。结论:栽培苦参与野生苦参都具有明显的清热、利尿和镇痛方面的作用,药效学作用强度比较野生与栽培苦参无显著差异,本实验结果为栽培苦参代替野生苦参提供了实验依据。     

Pharmacological Study of Cuscuta campestris Yuncker

The dried ethanol extract of the whole plant of Cuscuta campestris Yuncker was studied for its analgesic, antipyretic, antiinflammatory as well as CNS-depressant activities. The extract was given orally at doses of 50 and 100 mg/kg. A significant protection against the p -benzoquinone-induced writhing response in mice was observed. A marked lowering of the body temperature of both hyperthermic as well as normothermic mice was produced. Therefore, the extract possesses a hypothermic rather than an antipyretic effect. A marked inhibition of the carrageenan-induced rat hind paw oedema was also obtained. Regarding its CNS action, the extract produced a decrease in the motor activity of mice placed on a rotarod. In the conditioned avoidance reaction test the percentage of failure to avoid electric shock was shown to be increased after administration of the extract without any effect on the escape behaviour of the trained rats. Therefore, the CNS-depressant activity of the extract seems to be due to a tranquillizing effect. It could be concluded that the extract possesses analgesic, hypothermic, antiinflammatory as well as CNS-depressant activities.
