Isoimperatorin (4-[(3-Methyl-2-butenyl)oxy]-7H-furo[3,2-g][1]benzopyran-7-one) is a medicinal herbal product that is isolated from the dried roots of Angelicae dahuricae. Isoimperatorin inhibits the cyclooxygenase-2 (COX-2) and COX-1-dependent phases of prostaglandin D2 (PGD2) generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner
