Isolated from the leaves of Myrcia multiflora, it exhibits inhibitory activity against aldose reductase. It has a role as a metabolite and an EC 1.1.1.21 (aldehyde reductase) inhibitor. It is a beta-D-glucoside, a flavanone glycoside, a monosaccharide derivative, a trihydroxyflavanone and a cinnamate ester. It is functionally related to a trans-4-coumaric acid."}]
