J Asian Nat Prod Res. 2010 Aug;12(8):680-4. doi: 10.1080/10286020.2010.490780.

Abstract

Three new flavane glucosides (1-3) were isolated from the leaves of Morus wittiorum. The structures with absolute configuration were determined on the basis of hydrolysis and spectroscopic methods including UV, IR, HR-ESI-MS, 1D, and 2D NMR.
