Galloylalbiflorin (6′-O-Galloylalbiflorin) is an androgen receptor (AR) antagonist (IC50=53.3 μM) and can be found in the roots of Paeonia lactiflora. Galloylalbiflorin shows anti-androgens activity[1].

ChEBI: 6'-O-galloylalbiflorin is a monoterpene glycoside that is albiflorin carrying a galloyl substituent at position 6. Isolated from the roots of Paeonia lactiflora. It has a role as a plant metabolite, an androgen antagonist and an antineoplastic agent. It is a beta-D-glucoside, a gamma-lactone, a gallate ester, a bridged compound, a monoterpene glycoside and a secondary alcohol. It is functionally related to an albiflorin.
