Hyaluronidase Inhibitors from Moutan Cortex Radicis

목단피의 Hyaluronidase 저해물질

From the 60% aqueous methanolic fraction of Moutan Cortex Radicis two hyaluronidase inhibitors were isolated and their structures were elucidated by spectroscopic methods. Their structures were identified as paeoniflorin (com-pound I) and oxypaeoniflorin (compound II). Compound I and II exhibited hyaluronidase inhibitory activities with $IC_{50}$ of 1.71 and 1.73mM, respectively.
