Two new arylbenzofuran diglucopyranosides, (2?R)-(-)-moracin-O-5',3?-ß-d-diglucopyranoside (1) and (2?R)-(-)-moracin-P-5',2?-ß-d-diglucopyranoside (2), along with known arylbenzofurans, moracin M 6-ß-d-glucopyranoside (3), and an isomeric mixture of R-(-)-moracin O (4) and R-(-)-moracin P (5), were isolated from the root bark of Morus alba L. The structure of the compounds was elucidated based on mass spectrometry, infrared, 1D and 2D nuclear magnetic resonance spectroscopic data.
