Two new galloylated monoterpene glycosides, 4-O-galloylalbiflorin and 4'-O-galloylpaeoniflorin, from the roots of Paeonia lactiflora (Paeoniae radix) grown and processed in Nara Prefecture, Japan.

Two new galloylated monoterpene glycosides, 4-O-galloylalbiflorin and 4'-O-galloylpaeoniflorin, were isolated from the roots of Paeonia lactiflora that had been grown and processed in Nara prefecture, Japan. Their structures were elucidated based on spectroscopic analysis. These compounds showed androgen receptor (AR) binding activity.
