Oxyresveratrol 2-O-β-D-Glucopyranoside 98% Purity Stilbene Glycoside Standard CAS 392274-22-5 Research Grade Reference Standard

• • • • • Product Overview

          Oxyresveratrol 2-O-β-D-Glucopyranoside is a naturally occurring stilbene glycoside found in various plants, particularly in mulberry (Morus alba) and related species. It is a positional isomer of the 3'-O-glucoside of oxyresveratrol and serves as an important reference standard for the quality control of mulberry products.

          With the molecular formula C₂₀H₂₂O₉ and a molecular weight of 406.38 g/mol, this compound appears as an off-white to pale yellow powder. It is soluble in methanol, ethanol, and DMSO. The product is supplied at ≥98% purity as determined by HPLC analysis.

          Synthetic Process

          Oxyresveratrol 2-O-β-D-Glucopyranoside is obtained through isolation from plant sources:

          1. Extraction: Mulberry wood or other plant material is extracted with aqueous alcohol.

          2. Chromatographic Separation: The extract is fractionated using column chromatography.

          3. Purification: Preparative HPLC yields the pure compound.

          4. Identity Confirmation: Structure is confirmed by NMR and mass spectrometry.
