Anti-inflammatory and anti-nociceptive potentials of Salacia lehmbachii leaves (original) (raw)

Anti-Inflammatory, Antipyretic and Anti-Nociceptive Activities of the Ethanol Stem Bark Extract of Salacia lehmbachii

British Journal of Pharmacology and Toxicology, 2017

The aim of this study is to scientifically elucidate the effects of Ethanol Stem Bark Extract (ESBE) on inflammation, pyrexia and pains induced in rats and mice, following the claim that decoction from stem-bark of Salacia Lehmbachii (SL) is used in treating feverish and painful conditions in southeastern parts of Nigeria. The anti-inflammatory activities of the ESBE of this plant were studied, using carrageenan and egg albumin-induced paw edemain albino Wistar rats; and antipyretic activities were examined, using Dinitrophenol and Brewer's yeastinduced pyrexia in Wistar rats, while acetic acid-induced writhing and tail immersion models were used for analgesic study. LD50 and ED50 of the ESBE were carried out to determine its safety and dosing regimen, respectively. Thirty animals were randomly selected and grouped into five with six animals per group for each experiment. Group 1 and 5 (controls) received 20 mL/kg of distilled water and150 mg/kg of aspirin and 10 mg/kg of morphine (tail immersion study) respectively; while groups 2 to 4 received 75, 150 and 300 mg/kg of the extract respectively. The ED50 was 150 mg/kg. The ESBE of SL exhibited significant (p<0.05) dose related effects in all the experimental models. Doses of 150 and 300 mg/kg abolished the induced edema, induced pyrexia and pains, highly comparable to respective positive controls. Therefore, ESBE of Salacia lehmbachii possesses potent antiinflammatory, antipyretic and analgesic activities, likely resulting from its phytochemical constituents. Hence, its folkloric use in herbal medicines for pains and fever is justified.

Antinociceptive and anti-inflammatory potential of extract and isolated compounds from the leaves of Salvia officinalis in mice

2012

Ethnopharmacological relevance: Salvia officinalis L. has been used as a traditional herbal medicine for gastric disturbances and inflammatory processes. This study investigated the toxicological, antinociceptive and anti-inflammatory effects of the hydroalcoholic extract (HE) from leaves of Salvia officinalis and its isolated compounds in mice. Materials and methods: Mice were treated with HE before the induction of nociceptive response by chemical agents (acetic-acid, formalin, glutamate, capsaicin and cinnamaldehyde). Total leukocytes and plasma extravasation induced by acetic acid and paw oedema induced by glutamate, capsaicin and cinnamaldehyde were also measured. The antinociceptive effect of carnosol and ursolic acid/oleanolic acid were evaluated on formalin and cinnamaldehyde models. Results: In the acute toxicity test the value of estimated LD50 for HE was 44.7579 g/kg. Oral administration of HE (10, 30 and 100 mg/kg) inhibited the number of writhings, total leukocytes and plasma extravasation induced by acetic acid. In the formalin test, HE reduced both neurogenic and inflammatory phases, effect that was affected by naloxone. The glutamate-, capsaicin-and cinnamaldehyde-induced nociception and paw oedema were reduced by HE at doses that did not affect the locomotor activity of mice in the open field test. Carnosol (10 mg/kg) and ursolic acid/oleanolic acid (30 mg/kg) inhibited the inflammatory phase of formalin and the nociception and mechanical allodynia induced by cinnamaldehyde. Conclusions: These results demonstrate that HE presents significant anti-inflammatory and also antinociceptive effects on chemical behavioral models of nociception that involves an opioid mechanism. In addition, carnosol and ursolic acid/oleanolic acid contained in this plant appears to contribute for the antinociceptive property of the extract, possibly through a modulatory influence on TRPA1-receptors. However, further studies regarding the precise site and the mechanism of action of HE and carnosol and ursolic acid/oleanolic acid merited exploring further.

Analgesic and Anti-inflammatory Properties of Salix alba Linn and Calotropis procera (Aiton) Dryand

The methanolic extracts of Salix alba Linn and Calotropis procera (Aiton) Dryand were tested for the analgesic and anti-inflammatory effects in white albino mice. The acetic acid writhing response in mice was used to assess analgesic activity and plethysmometric measurement of formalin-induced paw edema was used to evaluate the anti-inflammatory activity of both the plant extracts. The extracts exhibited a dose-dependent analgesic action. S. alba extracts showed more potency than the standard drug aspirin in all the doses tested and C. procera extract showed prominent response in comparison to aspirin at doses as high as 62.5 mg/kg of plant extracts. The result also indicates that the extracts inhibited the paw edema size and shows inhibition of the inflammation (*p<0.05) well above the inhibitory effect of the aspirin (100mg/kg i.p). Acute toxicity tests showed that both of the plant extracts had no significant toxicity up to the dose of 125 mg/kg body weight. Phytochemical screening showed the presence of alkaloids, tannins and glycosides in both the plants. The results indicated that both of the extracts possesses significant analgesic as well as anti-inflammatory properties.
