Ononin

Ononin is an isoflavone glycoside, the 7-O-β-D-glucopyranoside of formononetin,[1] which in turn is the 4'-O-methoxy derivative of the parent isoflavone daidzein.

Natural sources

Ononin is a major isoflavone [2] found in a number of plants and herbs like soybean [3] and Glycyrrhiza uralensis.[4]

Pharmacokinetics

Intestinal bacterial metabolic pathways may include demethylation and deglycosylation.[5] It follows that formation of formononetin and/or daidzein is possible.

Pharmacodynamics

An in vitro anti-inflammatory effect on lipopolysaccharide (LPS)-induced inflammation has been demonstrated in one study.[6]
