Antinociceptive and antipyretic activities of the Zizyphus oxyphylla Edgew. leaves.Phytother Res. 2007 Jul; 21(7):693-5.PR
A methanol extract of Zizyphus oxyphylla Edgew leaves has been investigated for its analgesic and antipyretic activities in Adult Wistar and Swiss albino mice of either sex at 50, 100 and 200 mg/kg orally. The extract demonstrated marked antipyretic activity against Brewer's yeast-induced pyrexia in rats. The extract demonstrated significant peripheral analgesic effect in the acetic acid-induced writhing test in mice. The phytochemical tests revealed that the extract contained alkaloids, anthraquinones, flavonoids, glycosides, phenols, resins, saponins and tannins using standard procedures. In conclusion, the present study suggests that the methanol extract of Zizyphus oxyphylla Edgew leaves possesses potent antipyretic and antinociceptive activities and thus validates its use in the treatment of pain and fever.
