Description
Summary:To evaluate the antiulcer and analgesic effects of the aqueous root extract of Lonchocarpus cyanescens (L. cyanescens) since the plant is said to have medicinal properties. The filtrate of the aqueous root extract of the plant (100 mg/mL) was used to evaluate for antiulcer activity in 20 rats divided into five groups of four rats each, which were Groups A, B, and C that received 100, 200 and 300 mg/kg doses respectively, while Group D was served as negative control and animals of Group E received 20 mg/kg dose of ranitidine. Indomethacin at a dose of 15 mg/kg was used to induce ulcer on the day of sacrifice. For acetic writhing test (antinociception), same design was used except that Group E received 100 mg/kg dose of acetyl salicylic acid as standard drug. Abdominal contractions were induced in the animals by intraperitoneal administration of 10 mL/kg of 0.6% of acetic acid. The aqueous root extract of L. cyanescens at all doses (100, 200 and 300 mg/kg) showed significant (P
