Paeonol

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.

[7] 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.

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