ABSTRACT
The present study was designed to evaluate analgesic potential of the methanolic extracts of the leaves of the both Glycosmis pentaphylla (Rutaceae) and Eugenia fruticosa (Myrtaceae). The analgesic activity was evaluated using the acetic acid (0.7% i.p.)-induced writhing inhibition method in swiss albino mice. The methanolic extract of leaves of Glycosmis pentaphylla, at the dose of 200 and 400 mg/kg body weight significantly (p<0.001) reduced the number of writhes with 31.97% and 44.21% of inhibition, respectively compared to control group. The methanolic extracts of leaves of Eugenia fruticosa significantly and dose dependently reduced the pain threshold (p<0.001) with 51.02 and 72.1% of writhing inhibition when compared to the control group at the dose of 200 and 400 mg/kg body weight, respectively which were comparable to that of the standard drug Diclofenac Na (65.31% inhibition of writhing, p<0.001). The results of the study demonstrated the potential antinociceptive activity of the methanolic extracts of the leaves of Glycosmis pentaphylla and Eugenia fruticosa which validated the traditional uses of the both plants in painful diseases and further investigations to elucidate the mechanism of action are required.
