Analgesic, anti-inflammatory, and antipyretic effects of Ixora coccinea.
Abstract Background: The present study was carried out to explore the potential of the ethanol extract of Ixora coccinea L. (IC) leaves as analgesic, anti-inflammatory and antipyretic agents using the hot-plate, acetic acid-induced writhing, carrageenan-induced paw edema and brewer's yeast-induced pyrexia tests in rodents. Methods: The extract was prepared by soaking the dried powdered leaves of IC in ethanol for 2 days. The filtrate thus obtained by filtration and evaporation was considered as a stock solution and was used in all experimental models. Results: Oral administration of IC (250 and 500 mg/kg) significantly (p<0.05) increased the reaction time in the hot-plate test. Ixora coccinea (250 and 500 mg/kg) produced 56.14% and 63.16% inhibition (p<0.05) in acetic acid-induced writhing. It also (250 and 500 mg/kg) produced significant (p<0.05) inhibition of paw edema pronounced at 6 h after carrageenan injection. Intraperitoneal administration of IC (250 and 500 mg/kg) lowered the body temperature in brewer's yeast-induced hyperthermia. Conclusions: Based on the findings, it may be concluded that the IC leaves possessed analgesic, anti-inflammatory, and antipyretic activities. Phytochemical constituents of IC leaves such as flavonoids, tannins, and triterpenes in ethanol extract could be correlated with its observed biological activities.
