What Is Resveratrol?
Resveratrol is a stilbene ingredient obtained from Polygonum cuspidatum root. Identified by CAS 501-36-0, it is offered in trans-resveratrol HPLC grades from 20% to 98%, with powder colors ranging from brown to white.
The trans-resveratrol assay is the relevant basis for comparing these grades. A lower-assay root extract contains a different balance of constituents from a highly purified powder. For nutrition and personal-care development, concentration, color and dispersion should be evaluated together when selecting the material for a specific formulation.
