Description:
Resveratrol is a naturally occurring
polyphenolic compound widely used as a functional raw material in
nutraceutical, food, and cosmetic formulations. Commercial resveratrol is
primarily derived from the root of Polygonum cuspidatum, also known as giant knotweed
or Japanese knotweed, through controlled extraction and purification processes
designed to obtain resveratrol-rich botanical material with consistent quality.
As a plant-derived ingredient, resveratrol
is typically supplied in powder form with standardized content. The most common
active form is trans-resveratrol, which represents the naturally occurring and
stable isomer specified in commercial quality standards. Depending on the
degree of processing, resveratrol may be supplied as a botanical extract with
defined resveratrol content or further refined into higher-purity resveratrol
powder suitable for precise formulation control in different application systems.
From a raw material perspective, Polygonum
cuspidatum roots are firm and fibrous in structure, reflecting their natural
plant origin. During processing, these roots are extracted and refined to
produce resveratrol-containing extracts with improved uniformity and
formulation compatibility. The finished resveratrol powder exhibits stable
physical properties and a slightly bitter, astringent profile characteristic of
polyphenol-rich botanical ingredients, which is considered a normal attribute
of resveratrol derived from giant knotweed.
HPLC analysis is applied to verify
resveratrol content and ensure batch-to-batch consistency. Produced under ISO
quality management systems and available with Halal and Kosher certification,
resveratrol meets the requirements of global markets that emphasize traceable
sourcing, standardized quality, and regulatory compliance. Due to its plant
origin, consistent resveratrol content, and formulation versatility,
