Stilbene and 2-Arylbenzofuran Glucosides from the Rhizomes of Schoenocaulon officinale

Two stilbene glucosides, oxyresveratrol 2-O-β-glucopyranoside and resveratrol 3,4′-O,O′-di-β-D-glucopyranoside, and a 2-arylbenzofuran glucoside, schoenoside, were isolated from the rhizomes of Schoenocaulon officinale, along with five known compounds, oxyresveratrol 3′-O-β-D-glucopyranoside, oxyresveratrol, resveratrol 3-O-β-D-glucopyranoside, mulberroside A and moracin M 3′-O-β-D-glucopyranoside. The structural elucidations were based on analyses of both physical and spectroscopic data.
