In the present study, 70% ethanol extract of Mimusops elengi Linn. bark was assessed for antiinflammatory, analgesic and antipyretic activities in animals. The antiinflammatory activity of ethanol extract of Mimusops elengi (200 mg/kg, p.o) was evaluated using carrageenan-induced paw edema and cotton pellet-induced granuloma models. Analgesic effect was evaluated using acetic acid-induced writhing and Eddy's hot plate models and antipyretic activity was assessed by Brewer's yeast-induced pyrexia in rats. The ethanol extract of Mimusops elengi (200 mg/kg, p.o) significantly inhibited the carrageenan-induced paw oedema at 3rd and 4th h and in cotton pellet model it reduced the transudative weight and little extent of granuloma weight. In analgesic models the ethanol extract of Mimusops elengi decreases the acetic acid-induced writhing and it also reduces the rectal temperature in Brewer's yeast induced pyrexia. However, Mimusops elengi did not increase the latency time in the hot plate test. These results show that ethanol extract of Mimusops elengi has an antiinflammatory, analgesic and antipyretic activity. 相似文献

In an attempt to ascertain the pharmacological basis of the use of the marketed traditional drug Taverniera abyssinica A. Rich. (Amharic name Dingetegna), crude extracts as well as purified substances of this plant were tested for their antipyretic and analgesic properties. Antipyretic activity was determined on rats made hyperthermic by yeast injection and analgesic activity was determined by the hot plate, as well as the acetic acid induced writhing, methods. The study showed that the plant possesses significant antipyretic and analgesic activities. 相似文献

AbstractThe effects of the defatted methanol extract of Entada abyssinica. Steud. ex A. Rich leaves on some models of inflammation were investigated. The analgesic property of the plant extract was also tested on acetic acid–induced writhing, as well as formalin-induced paw licking, in mice. The antipyretic effect was evaluated using yeast-induced hyperpyrexia in mice. At doses of 50–200 mg/kg, the extract produced significant (p < 0.05) inhibition of leukocyte migration after intraperitoneal injection of carrageenan in rats. A topical anti-inflammatory effect was produced by 20 mg/ear of the extract, as demonstrated by inhibition of croton oil–induced ear edema in mice. The analgesic property of the plant extract was observed by inhibition of acetic acid–induced writhing and paw licking induced by formalin in mice. The extract, however, exhibited no antipyretic activity. This study further established the anti-inflammatory activity of E. abyssinica., in addition to its analgesic effect. 相似文献
