Inhibition of COX-2 and iNOS protein expression by BuOH extract of M. leucadendron L. in LPS-stimulated RAW264.7 cells. Cells were pretreated with the indicated concentrations of BuOH extract for 1 hr before being incubated with LPS (10 μg/mL) for 24 hr. Cell lysates were then prepared and subjected to western blotting using an antibody specific for COX-2 and iNOS. β-actin was used as an internal control.
