MPO and edema: The methanolic extracts of H. brachiata and H. cotinifolia exhibited significant anti-inflammatory activities in the TPA-induced ear edema, while only H. cotinifolia exerted significant anti-inflammatory activities in the MPO assay (>45%) and also exhibited a higher percentage of inhibition on AChE of even twice (>80%) as high as the control in concentrations of 100 and 1000 μg/mL.
