Résumé
Objective Cleome rutidosperma (Capparidaceae), commonly known as “Fringed Spider Flower”, is a medicinal plant found in Southeast Asia. C. rutidosperma is used in folk medicine for diuretic, laxative, analgesic, anti-inflammatory, antipyretic, antimicrobial, anti-oxidant, hypoglycemic, and anthelmintic activities. We have evaluated the anti-nociceptive properties of methanol extract from C. rutidosperma (MECR) in vivo. Methods Thermal method (hot plate test and tail flick test) was induced to judge the anti-inflammatory effect and couple of chemical method also used (formalin induced licking test; writhing test carried by acetic acid) to evaluate analgesic effect. Both of these tests were made over animal models, like mice and rats. Two different doses (100 and 200 mg/kg) were used for each case of test, while morphine sulphate (5mg/kg, ip) was used as reference drug. Results MECR demonstrated the significantly anti-nociceptive activity in the analgesic and anti-inflammatory tests by reducing nociception in mice models (P < 0.001). In the hot-plate and tail-flick tests, MECR significantly elongated the time to response to the thermal stimuli (100 and 200 mg/kg with P < 0.05, 0.001). The remarkable increase in the latency was observed at 90 and 120 min. In acetic acid-induced writhing test and formalin induced licking test for anti-inflammatory activity, MECR at 100 and 200 mg/kg doses exhibited significant (P < 0.001) reduction of writhing and licking response. Conclusion The anti-inflammatory and analgesic effects of C. rutidosperma propose that this effect may be a result of both peripheral and central mechanisms. Further study is required to ensure the proper mechanism of action as well as the active ingredient.
Résumé
The petroleum ether, chloroform, methanol and aqueous extracts of Cleome rutidosperma DC (Family: Capparidaceae) roots were evaluated for their wound healing activities in rats using excision and incision wound models respective-ly. The effects of test samples on the rate of wound healing were assessed by the rate of wound closure, period of epithelialisation and wound breaking strength. Nitrofurazone (0.2% w/w) in simple ointment I.P. was used as reference standard for the activity comparison. The results of the study revealed that the animals treated with methanol and aqueous extracts of C. rutidosperma showed faster rate of wound healing compared to other extracts under study. The chloroform extract of the selected plant also produced promising results but the effects are seen to be of lesser extent than the corresponding methanol and aqueous extracts. The petroleum ether extract did not produce significant results. The present work justifies the use of C. rutidosperma roots for wound healing activity as claimed in the folklore literature.
