Isolated from Sedum sarmentosum, it exhibits inhibitory activity against angiotensin-converting enzyme. It has a role as a metabolite and an EC 3.4.15.1 (peptidyl-dipeptidase A) inhibitor. It is a disaccharide derivative, a cinnamate ester and a quercetin O-glycoside. It is functionally related to a trans-caffeic acid."}]
