Anti-inflammatory activities of A. pyrethrum roots methanolic extract (ME), methylene chloride (MCF), and butanol (BF) fractions in vitro against COX-2 and 5-LOX, as well as in LPS-induced RAW264.7 macrophages (iNOS). Different letters on the bar indicate significant differences at P < 0.0001 with Tukey’s test. Standards: Celecoxib (COX 2), Zileuton (5-LOX), and parthenolide (iNOS) are serving as positive controls
