A Comparative Study of Analgesic, Antidiarrhoeal and Antimicrobial Activities of Methanol and Acetone Extracts of Fruits Peels of Limonia acidissima L. (Rutaceae)

Objectives: Present study was designed to evaluate Analgesic, Antidiarrhoeal and Antimicrobial activities of methanol and acetone extracts of fruit peels of Limonia acidissima L. by different methods. Method: The analgesic activity of the samples was studied using acetic acid- induced writhing model in mice. Castor oil-induced antidiarrheal activity was observed by Thomas method and antimicrobial activity was monitored by disc diffusion method. Results: Limonia acidissima L. inhibited 60.53 % and 59.65 % writhing of methanol as well as acetone fruit peels extracts, respectively, compared to standard drug Diclofenac Na inhibited 78.07 % writhing. At higher dose (500 mg/kg) of the methanol and acetone fruit peels extracts, significant inhibition 47.13 and 44.83 % of characteristic diarrhoeal feces was observed, respectively, as well as at lower dose (250 mg/kg) of the both extracts, inhibition 34.45 and35.63 %. Mention able on average 12mm zone of inhibition was observed of both extract at 250µg/disc and 500µg/disc compare to zone of inhibition 36mm of ciprofloxacin at 50µg/disc. Conclusion: From the above results, it will be very much possible source for an isolating lead compound for curing the numerous disorders. Keywords: Limonia acidissima L.
