Effect of the essential oil of Spondias pinnata (EOSP) on NO production in RAW 264.7 cells. Results were expressed as percentages of NO by control cells maintained in culture medium. Values are presented as mean ± standard deviation (SD) of three independent tests. ### p < 0.001 for LPS versus the blank group. *** p < 0.001 for cells treated with essential oil samples versus the control group (LPS).
