ABSTRACT
The aqueous extract of Croton cuneatus Klotz. (Euphorbiaceae), was tested for its antinociceptive effects using chemical and thermal test models in mice. Anti-inflammatory activity was determined in Sprague-Dawley rats in a model of acute plantar inflammation induced by bovine serum albumin. Croton cuneatus aqueous extract at doses of 7 mg/kg showed a significant anti-inflammatory effect compared with commonly used non-stereoidal drugs as ketoprofen, sodium diclofenac and ASA (acetylsalicylic acid).

Croton malambo (K.) bark aqueous extract, popularly known in Venezuela as "palomatias" or "torco" was tested for acute toxicity and for its anti-inflammatory and antinociceptive effects using tail flick and writhing syndrome tests models, respectively. Croton malambo aqueous extract (6.15 mg/kg i.p.) administered intraperitoneally had a significant antinociceptive and anti-inflammatory effects compared to acetylsalicylic acid (200mg/kg p.o.) and sodium diclofenac (5.64 mg/kg p.o.). Studies to determine correlation between chemical composition and pharmacological activity are underway.
