Effect of fractions of H-hexane, D-DCM, E-EtOAc and B-BuOH at 100 mg/kg of M. tenuiflora bark extract on paw edema after administration of formalin 1.5% (i.pl).
VH is the vehicle group (negative control). Indomethacin (I, 10 mg/kg, i.p.) was the positive control group. Results are presented as mean ± S.D. (n = 8). Statistical significance was calculated by ANOVA followed by Bonferroni's test. *P < 0.05 compared to the vehicle-negative control treated group. •P > 0.05 compared to indomethacin-treated group.
