Antinociceptive, antiinflammatory and acute toxicity effects of Salvia leriifolia Benth seed extract in mice and rats.
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.
