Oral administration of the ethanolic extract (200 and 400 mg/kg, p.o) and its fractions (200 mg/kg each) of the aerial parts of Cleome rutidosperma produced significant analgesic activity in acetic acid-induced writhing and tail immersion tests, anti-inflammatory effect against carrageenin induced inflammation and adjuvant induced polyarthritis and antipyretic activity against yeast-induced pyrexia. Fractionation of the ethanolic extract potentiated the activities. 相似文献

The species of Glaucium have been used in Iranian herbal medicine in the treatment of dermatitis. Due to anti-inflammatory and analgesic activity of Glaucium grandiflorum methanolic extract in i.p. administration, these effects in topical administration were studied using carrageenan-induced edema and formalin test. Several formulations were prepared and the best cream was chosen as vehicle. Piroxicam gel and methyl salicylate ointment were studied as positive control for anti-inflammatory and analgesic activity, respectively. The edema inhibition of preparations containing extract at the doses of 1-5% w/w were significantly different from control group. The anti-inflammatory effect of MS4-5% was similar to the effect of piroxicam gel at 3 h after carrageenan injection. Topical preparation containing G. grandiflorum methanolic extract showed analgesic effect in concentrations more than 4% w/w in early phase in formalin test. This activity was observed in concentrations more than 3% w/w in late phase. The topical analgesic activity of extract was less than the analgesic activity of methyl salicylate ointment. 相似文献

The aqueous extracts of Datura fastuosa leaves and seeds were evaluated for the analgesic effect on acetic acid-induced writhing and hot plate reaction in mice. According to the results, D. fastuosa leaves and seeds extracts at oral doses of 400 and 800 mg/kg are effective as analgesic. The analgesic activity of leaf extract is reduced by naloxone but not that of seed extract. 相似文献

Antinociceptive effect of hydroalcoholic extract and essential oil of Zataria multiflora was studied using writhing, tail flick and formalin tests. In tail flick test, the hydroalcholic extract (500 mg/kg, i.p.) and the essential oil (0.3 ml/kg, i.p.) of the plant showed antinociceptive activity (P<0.05). Moreover, they showed antinociceptive activity in writhing and formalin tests. 相似文献

The root barks of Zizyphus lotus were extracted with water, chloroform, ethyl acetate and methanol to determine their antiinflammatory and analgesic activities. Aqueous extract (50, 100 and 200 mg/kg) given intraperitoneally (i.p.) showed a significant and dose-dependent antiinflammatory and analgesic activity. 相似文献

Anti-inflammatory and analgesic activity of Bouchea fluminensis 总被引：1，自引：0，他引：1
Dried leaves extract from Bouchea fluminensis was assessed in anti-inflammatory (mouse paw edema) and analgesic models (acetic acid-induced writhings and hot plate). Oral pretreatment of animals with a crude mixture (IG) and a purified mixture of ursolic, oleanolic and micromeric acids (IG-59) at doses ranging from 1 to 30 mg/kg, significantly inhibited carrageenin-induced edema formation. At the same doses, IG and IG-59 also exhibited peripheral and central analgesic activity. It seems that B. fluminensis triterpenes develop their analgesic effect through central opioid receptors, due to the observation that naloxone reverted analgesic activity on the hot plate model. 相似文献

The alcoholic extract of the flowers of Calotropis gigantea was administered orally and explored for its analgesic activity in chemical and thermal models in mice. In acetic acid induced writhing test, an inhibition of 20.97% and 43.0% in the number of writhes was observed at the doses of 250 and 500 mg/kg, respectively. In the hot plate method the paw licking time was delayed. The analgesic effect was observed after 30 min of dose administration which reached its maximum after 90 min. 相似文献

A new steroidal derivative, urs Stigmast-4, 20 (21), 23-trien-3-one and other four compounds were isolated from the leaves of Bryophyllum pinnatum. The structure of this new steroid was elucidated and established by standard spectroscopic methods. Carrageenan induced paw edema model was used for anti-inflammatory and acetic acid induced model used for analgesic activity. This new steroidal compound was found to be active in reducing inflammation (% inhibition 87.29 and 84.45 respectively) when compared with diclofenac. Further, it showed 75.72% protection in analgesic activity in acetic acid induced writhing test in mice. In conclusion the % inhibition against carrageenan induced rat paw edema and % protection against acetic acid induced writhings showed by new compound revealed that the anti-inflammatory and analgesic activity of aqueous extract B. pinnatum are mainly due to the presence of this steroidal compound. 相似文献

Fractions of methanol, dichloromethane, water extracts and volatiles of Carthamus lanatus aerial parts given by oral route at a dose of 2 mg/kg showed significant antiinflammatory activities in rats. On the contrary, only the water fraction of MeOH extract possesses a significant analgesic activity. 相似文献

Moreover, when given orally to rats at dose of 200 and 400 mg/kg, it showed a significant anti-inflammatory activity against carrageenin induced rat paw edema in rats. 相似文献

The crude extract of Mikania cordata (1 and 3 g/kg, p.o.) and deoxymikanolide (1) (10 mg/kg, p.o.) significantly inhibited acetic acid-induced writhing in mice. Three other sesquiterpene dilactones isolated from the same plant, namely mikanolide, dihydromikanolide and scandenolide, did not show significant analgesic activity. 相似文献

The aqueous extract of Ficus deltoidea leaves was evaluated for possible antinociceptive activity in three models of nociception, namely, acetic acid-induced abdominal writhing, formalin and hot plate test. The results of the present study showed that intraperitoneal administration of the F. deltoidea leaves aqueous extract at the dose of 1, 50 and 100 mg/kg, 30 min prior to pain induction produced significant dose-dependent antinociceptive effect in all the models used, which indicating the presence of both central and peripherally mediated activities. Furthermore, the antinociceptive effect of the extract in the formalin and hot plate test was reversed by the non-selective opioid receptor antagonist naloxone suggesting that the endogenous opioid system is involved in its analgesic mechanism of action. Thus, the present results demonstrated that F. deltoidea leaves aqueous extract contains pharmacologically active constituents which possess antinociceptive activity justifying its popular therapeutic use in treating conditions associated with the painful conditions. 相似文献

A chemical and biological validation of the traditional use of Hyoscyamus niger seeds as anti-inflammatory drug has been established. The methanolic extract of seeds of H. niger (MHN) was evaluated for its analgesic, anti-inflammatory and antipyretic activities in experimental animal models at different doses. MHN produced significant increase in hot plate reaction time, while decreasing writhing response in a dose-dependent manner indicating its analgesic activity. It was also effective in both acute and chronic inflammation evaluated through carrageenin-induced paw oedema and cotton pellet granuloma methods. In addition to its analgesic and anti-inflammatory activity, it also exhibited antipyretic activity in yeast-induced pyrexia model. Furthermore, the bioactive MHN under chemical investigation showed the presence of coumarinolignans as major chemical constituent and yielded a new coumarinolignan, cleomiscosin A methyl ether (1) along with four known coumarinolignans, cleomiscosin A (2), cleomiscosin B (3), cleomiscosin A-9′-acetate (4) and cleomiscosin B-9′-acetate (5). The structure elucidation of 1 was done by spectroscopic data interpretation and comparative HPLC analysis. Cleomiscosin A, but not its isomer cleomiscosin B, reduced dry and wet weight of cotton pellet granuloma in mice. This suggests that cleomiscosin A is an important constituent of MHN responsible for anti-inflammatory activity. 相似文献
