Enzyme-hydrolyzed Fruit of Jurinea mollis: a Rich Source of (-)-(8R,8'R)-Arctigenin.

In Jurinea mollis fruit, the dibenzylbutyrolactone-type lignan glycoside arctiin and its aglycone arctigenin were determined for the first time using a combination of optimized enzymatic treatment and complementary spectrometric (HPLC-MS, GC-MS) and spectroscopic (CD and NMR) methods. Analysis of separated fruit parts, i.e.
