  1. Defatted methanol extract (ATD); n-hexane extract (ATH); Cyclooxygenase (COX); The half of the inhibitory concentration (IC50). Selectivity index (SI) = IC50 COX-1/IC50 COX-2. Data in the Table expressed mean ± SEM (n = 3). Where ***P < 0.001 consider statistically significant compared to ibuprofen and ###P < 0.001 consider statistically significant compared to ATH group using one-way ANOVA followed by Tukey’s post hoc test
