Three new flavane glucosides from the leaves of Morus wittiorum.
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.
