Figures & data
Figure 1. Effects of the methanol, hexane and EtOAc extracts (A), and hexane and EtOAc fractions (B and C, respectively) of K. monocephala leaves administered orally against abdominal constriction induced by 10 mL/kg i.p. injection of 0.7% acetic acid. Unless specified, samples were administered at 250 mg/kg body weight. Ibuprofen was used as positive control, given at 5.7 mg/kg. Points represent the mean number of writhes of 5 animals, with vertical bars indicating SEM. In some cases the SEM is hidden in data points. Asterisks denote significant levels when compared against the acetic acid (*) or corn oil (**) control groups, P <0.05. Percentage analgesic activities of the extracts and fractions are shown in D, where those with significant activities are indicated by asterisks.
