Myrtus communis L. aerial parts have been used in traditional medicine for the treatment of inflammatory disease. In this study 350 mice were divided into three main groups: negative (saline), positive (morphine or diclofenac) controls, and test groups. The acute toxicity was assessed for 2 days. Antinociceptive activity was performed using hot plate and writhing tests. The anti-inflammatory effect was investigated using xylene-induced ear edema and a cotton pellet test. According to phytochemical screening, the extracts contained tannins, alkaloids, and flavonoids. The LD50 values of the aqueous and ethanolic extracts were 0.473 and 0.79 g/kg, respectively. In hot plate test, the aqueous and ethanolic extracts showed significant antinociceptive activity that was inhibited by naloxone. The extracts exhibited antinociceptive activity against acetic acid-induced writhing and also showed significant activity against acute inflammation which was dose dependent for aqueous extract. The ethanolic (0.05 g/kg) and aqueous extracts (0.005, 0.015, and 0.03 g/kg) demonstrated anti-inflammatory effects against chronic inflammation. The aqueous and ethanolic extracts of the aerial parts of M communis L. showed antinociceptive effects and these may be mediated by opioid receptors. 相似文献

The antinociceptive and antiinflammatory effects as well as the acute toxicity of Salvia leriifolia aqueous seed extract were studied in mice and rats. Antinociceptive activity was assessed using the hot-plate and tail flick tests. The effect on acute inflammation was studied using vascular permeability increased by acetic acid and xylene-induced ear oedema in mice. The activity against chronic inflammation was assessed using the cotton pellet test in rats. The LD(50) of the extract was found to be 19.5 g/kg (i.p.) in mice. The aqueous seed extract showed significant and dose-dependent (1.25-10 g/kg) antinociceptive activity over 7 h, and was inhibited by naloxone pretreatment. Significant and dose-dependent (2.5-10 g/kg) activity was observed against acute inflammation induced by acetic acid and in the xylene ear oedema test. In the chronic inflammation test the extract (2.5-5 g/kg) showed significant and dose-dependent antiinflammatory activity. The aqueous seed extract of S. leriifolia may therefore have supraspinal antinociceptive effects which may be mediated by opioid receptors, and showed considerable effects against acute and chronic inflammation. 相似文献

The present study investigates the analgesic and topical anti-inflammatory activities of the infusion, methanol extract and fractions of the aerial part in blossom of Hypericum canariense L. and Hypericum glandulosum Ait. in mice. The acetic acid-induced writhing test, tail flick test and the tetradecanoylphorbol acetate (TPA)-induced ear inflammation model in mice were used to determine these effects. Our findings show that oral administration of methanol extracts, and the aqueous, butanol and chloroform fractions of both species and the infusions of Hypericum glandulosum significantly inhibit acetic acid-induced writhing in mice. Only the infusion, methanol extract and butanol and chloroform fractions of Hypericum glandulosum were significantly active in the tail flick assay, suggesting that they may have central analgesic properties. On the other hand, the topical treatment of all extracts tested from both species, with the exception of the infusions and the Hypericum canariense aqueous fraction, significantly reduced the TPA-induced ear oedema. In conclusion, the results indicate analgesic and topical anti-inflammatory activities in mice for the Hypericum species studied. 相似文献

The present study investigates the analgesic and topical anti-inflammatory effects of the infusion, methanol extract and fractions of the aerial part in blossom of Hypericum reflexum L. fil. in mice. The acetic acid-induced writhing test, formalin test, tail flick test and the tetradecanoylphorbol acetate (TPA)-induced ear inflammation model in mice were used to determine these effects. Our findings show that oral administration of all extracts tested from this species significantly inhibit acetic acid-induced writhing in mice. Only the methanol extract and chloroform fraction were significantly active in both phases of formalin-induced pain and in the tail flick assays, suggesting that they may have central analgesic properties. On the other hand, the topical treatment of methanol extract, butanol and chloroform fractions of this species significantly reduced the TPA-induced ear oedema. In conclusion, the results indicate analgesic and topical anti-inflammatory activities in mice for the Hypericum species studied. 相似文献

Ethnopharmacological relevance
Agastache mexicana is a plant that has long been used in large demand in Mexican folk medicine to treat pain, among others affections. Nevertheless, no scientific data confirming its use have been reported. The aim of this investigation was to examine the spectrum of antinociceptive activity of A. mexicana by using different experimental models of nociception in rodents.Material and methods
Nociceptive activity was induced 30 min post treatment of different doses of hexane, ethyl acetate and methanol extracts from A. mexicana aerial parts. The writhing test in mice, and the formalin and plantar tests as well as the pain-induced functional impairment assay in rats (PIFIR model) were the experimental nociceptive models used. Antinociceptive response of the organic extracts was compared to that observed with the analgesic drug tramadol.Results
A. mexicana organic extracts produced a dose-dependent and significant inhibition of the abdominal constrictions caused by 1% acetic acid injection (i.p.) in mice. A maximal antinociceptive effectiveness obtained with tramadol was also observed with the administration of hexane and ethyl acetate extracts in comparison to less effectiveness obtained with the methanol extract. At the same range of doses, A. mexicana organic extracts inhibited the behavioral responses in both phases of the formalin pain test, in which a more intense effect was observed in the inflammatory phase than in the neurogenic stage. With regard to the plantar test and PIFIR model, a significant but not dose-dependent antinociceptive response was observed at specific doses that depended on the organic extract evaluated.Conclusion
The antinociceptive activity of A. mexicana aerial parts depends on the intensity of the painful stimulus induced and involves different kinds of constituents. Our present results reinforce the use of this species in traditional medicine and its utility for pain treatment mainly associated with inflammation. 相似文献10.
Extracts obtained from the root and aerial parts of various Eryngium (Apiaceae) species are used as folk remedy worldwide for the treatment of various inflammatory disorders. Ethanolic and aqueous extracts obtained from either aerial parts or roots of eight Eryngium species growing in Turkey, i.e., were evaluated for their in vivo anti-inflammatory and antinociceptive activities. Eryngium campestre, Eryngium creticum, Eryngium davisii, Eryngium falcatum, Eryngium isauricum, Eryngium kotschyi, Eryngium maritimum, and Eryngium trisectum. For the antinociceptive activity assessment p-benzoquinone-induced writhing test, and for anti-inflammatory activity carrageenan-induced hind paw oedema and TPA-induced ear oedema tests were employed in mice. According to the results of investigations, except Eryngium falcatum extracts, ethanol extracts either from the aerial parts or roots of Eryngium species showed apparent anti-inflammatory and antinociceptive activity. In spite of potent activity of the ethanol extract from Eryngium isauricum aerial parts was induced gastric damage. Aerial parts and roots of Eryngium maritimum and Eryngium kotschyi were found to possess most promising activities without including any apparent gastric damage. 相似文献

Extracts obtained from the dried aerial parts of Clematis species are used as folk remedy worldwide for the treatment of various inflammatory ailments such as rheumatism and to reduce fever. In order to test the effectiveness of extracts, fractions and subfractions from dried Clematis vitalba L. (Ranunculaceae) aerial parts were studied on mice. Extracts are shown to have a potent effect on carrageenan-induced hind paw edema and acetic acid-induced increased vascular permeability models. Through bioassay-guided fractionation procedures a new C-glycosylflavon, 4′-O-coumaroyl-isovitexine (vitalboside) was isolated as the main active ingredient of the aerial parts. Vitalboside showed a potent and dose-dependent (in 75 and 150 mg/kg does, per os) in vivo anti-inflammatory activity against acute (carrageenan-, serotonin- and PGE2-induced hind paw edema model, castor oil-induced diarrhea), subacute (subcutaneous air-pouch) and chronic (Freund's complete adjuvant-induced arthritis) models of inflammation. The same compound was also isolated as the main antinociceptive principle which was assessed by using the models based on the inhibition of p-benzoquinone-induced writhings, as well as antipyretic activity against Freund's complete adjuvant-induced increased body temperature. Acute and subchronic toxicity studies were also performed. 相似文献

Satureja hortensis L. (Lamiaceae) is a medicinal plant used in Iranian folk medicine as muscle and bone pain reliever. In the present study, hydroalcoholic extract, polyphenolic fraction and essential oil of the aerial parts of the herb were prepared and evaluated for the analgesic activity using light tail flick, formalin and acetic acid-induced writhing in mice. Also, the anti-inflammatory effects of the above-mentioned preparations were assessed using carrageenan-induced paw edema in rats. Results showed that in the light tail flick test neither the essential oil nor the extracts could exert any significant effect. The hydroalcoholic extract (2000 mg/kg, p.o.) and the essential oil (200 mg/kg, p.o.) inhibited the mice writhing responses caused by acetic acid. In formalin test, hydroalcoholic extract (500-2000 mg/kg, p.o.), polyphenolic fraction (250-1000 mg/kg, p.o.) and the essential oil (50-200 mg/kg, p.o.) showed analgesic activity and pretreatment with naloxone (1 mg/kg, i.p.) or caffeine (20 mg/kg, i.p.) failed to reverse this antinociceptive activity. Polyphenolic fraction (1000 mg/kg, p.o.) and the essential oil (200 mg/kg) reduced edema caused by carrageenan. These results suggest that S. hortensis L. has antinociceptive and anti-inflammatory effects and probably mechanism(s) other than involvement of opioid and adenosine receptors mediate(s) the antinociception. 相似文献

Methanolic extracts from the heart wood, stem bark, and stem wood of Ventilago harmandiana Pierre (Family Rhamnaceae) were assessed for anti-inflammatory effects using both acute and chronic inflammatory models. Analgesic and antipyretic activities of the extracts were also evaluated. It was found that all extracts possessed strong inhibitory effects on the acute phase of inflammation as seen in ethyl phenylpropiolate (EPP)- and arachidonic acid (AA)-induced ear edema as well as in carrageenin-induced paw edema in rats. The extracts elicited only weak inhibitory activity on cotton pellet-induced granuloma formation, a subchronic inflammatory model. In the analgesic test, all extracts exerted pronounced inhibitory activity in acetic acid-induced writhing response but showed only weak effects in the tail-flick test. The extracts also showed excellent antipyretic activity on yeast-induced hyperthermia in rats. 相似文献
