What is Resveratrol?
Resveratrol powder is a phenolic compound, a stilbene, created by plants in response to injury, infection, and fungal attack. It exists in trans- and cis-molecule forms, with trans-resveratrol being highly-absorbable.
Resveratrol can be found in several natural sources, including grapes, berries, and nuts like peanuts. Some of the most common ones include grapes, particularly in the skin and seeds of the red and purple varieties. Japanese Knotweed (Polygonum cuspidatum) is one of the most abundant natural sources. Peanuts, especially when boiled or roasted, and certain berries like blueberries, cranberries, and bilberries also contain resveratrol. Small quantities can be found in cocoa and dark chocolate. Additionally, red wine contains resveratrol due to the fermentation process involving grape skins.
Polygonum cuspidatum Extract, also known as Japanese Knotweed extract, is the most popular natural resveratrol source. The popular specification is 50% resveratrol and 98% resveratrol powder.
Resveratrol Manufacturing Process
Manufacturing natural resveratrol with a purity of 98% involves several steps:
- Raw Material Collection: The primary source of natural resveratrol is the root of the Polygonum cuspidatum plant, also known as Japanese Knotweed. These roots are harvested and cleaned.
- Extraction: The cleaned roots are then subjected to extraction processes to remove the resveratrol. Standard methods include solvent extraction, enzymatic extraction, microwave extraction, and supercritical CO2 extraction.
- Purification: After extraction, the crude extract contains resveratrol and other compounds. This mixture is then purified to isolate resveratrol. Standard methods include column chromatography and recrystallization.
- Refinement: The purified resveratrol is refined to increase its purity to 98%. This can be achieved through repeated crystallization or high-performance liquid chromatography (HPLC).
- Drying: The refined resveratrol is dried to remove any remaining solvents and moisture.
- Packaging: The dried product is tested for purity, and if it meets the 98% standard, it is packaged and prepared for distribution.
