The molecule is a member of the class of isoflavans that is isoflavan with hydroxy substituents at positions 4, 7 and 4' and a methoxy group at position 2 (the 3R,4S stereoisomer). It is isolated from Caragana conferta and exhibits significant anti-inflammatory activity in the respiratory burst assay. It has a role as a metabolite and an anti-inflammatory agent. It is a secondary alcohol, a monomethoxybenzene and a member of hydroxyisoflavans.
