Paeonol is a phenolic compound found in peonies[2] such as Paeonia suffruticosa (moutan cortex),[3][4] in Arisaema erubescens,[5] and in Dioscorea japonica.[6] It is a chemical compound found in some traditional Chinese medicines.[7]

Biological effects

A number of biological effects of paeonol in vitro or in animal models have been observed. Paeonol increases levels of cortical cytochrome oxidase and vascular actin and improves behavior in a rat model of Alzheimer's disease.[8] Paeonol also reduced cerebral infarction involving the superoxide anion and microglia activation in ischemia-reperfusion injured rats.[9]

Paeonol shows antimutagenic activities.[3][6] It also has anti-inflammatory and analgesic effects in carrageenan-evoked thermal hyperalgesia.[10] Paeonol inhibits anaphylactic reaction by regulating histamine and TNF-α.[11]

Paeonol has weak MAO-A and MAO-B inhibiting effects with IC50 values of 54.6 μM and 42.5 μM respectively.[12]

Metal complex

Metal complexes of paeonol shows tetrahedral and octahedral coordination geometry in the absence and presence of solvent pyridine respectively.[13]
