Abstract: The present study reports the potential antinociceptive, anti-inflammatory and hepatoprotective activities of lycorine from Sternbergia fischeriana (Herbert) Rupr. (Amaryllidaceae). Lycorine was evaluated on mice by using acetic-acid induced writhing and tail-flick tests. Lycorine exhibited stronger inhibition than aspirin in acetic-acid induced abdominal stretching at 1.0mg/kg dose. Lycorine also showed antinociceptive activity at 1.0mg/kg dose in tail-flick test. The anti-inflammatory activity of lycorine was not found to be significant at dose of 0.5mg/kg. However, at doses of 1.0mg/kg and 1.5mg/kg, i.p. showed a significant reduction with 53.45% and 36.42%, respectively in rat paw oedema induced by carrageenan against the reference anti-inflammatory drug indomethacin (3mg/kg, i.p.) (95.70%). The ED50 of lycorine was determined as 0.514mg/kg. Hepatoprotective activity of lycorine on carbon tetrachloride (CCl4) induced acute liver toxicity following biochemical parameters were also evaluated. Rats were treated with lycorine at doses of 1.0mg/kg and 2.0mg/kg, i.p. Results of biochemical tests were confirmed by histopathological examination. Lycorine exhibited significant hepatoprotective effect at dose of 2.0mg/kgi.p. dose. [Copyright &y& Elsevier]

Water extract of Viburnum opulus L. (Caprifoliaceae) (VO) leaf was investigated for antinociceptive and anti-inflammatory activities in mice and rats. The tail flick test, acetic acid-induced writhing test, and the carrageenan-induced rat paw edema test were used to determine these effects. Our findings show that VO causes dose related inhibition in acetic acid-induced abdominal stretching in mice. VO inhibited abdominal stretching at 100 and 200 mg/kg. VO showed antinociceptive activity, which was quantified by the tail-flick test at doses of 100 and 200 mg/kg. However, VO did not have an anti-inflammatory effect at these doses. The LD50 of VO was determined as 5.447 g/kg. [ABSTRACT FROM AUTHOR]

The water extract of Ballota inaequidens Hub.-Mor. & Patzak (Lamiaceae) was investigated for antinociceptive and anti-inflammatory activities in mice and rats. The tail-flick test, acetic acid–induced writhing test, and the carrageenan-induced rat paw edema test were used to determine these effects. Our findings show that Ballota inaequidens caused dose-related inhibition in the acetic acid–induced abdominal stretching in mice. The medium effective dose (ED50) value of Ballota inaequidens was found to be 85.38 mg/kg. Ballota inaequidens showed no significant changes in the nociceptive threshold of the tail-flick test but did show an inhibition of paw edema induced by carrageenan. The ED50 value of Ballota inaequidens was found to be 99.42 mg/kg. The current study reveals that the water extract of Ballota inaequidens possesses promising antinociceptive and anti-inflammatory activities. [ABSTRACT FROM AUTHOR]
