Description of Resveratrol:
Huzhang ("tiger cane") or giant knotweed is an east Asian species (Polygonum cuspidatum), belonging to the Polygonaceaefamily. Documented uses in traditional Chinese medicine date to the first century BC, and contemporary medical uses supported by clinical results include acute microbial infections or viral hepatitis, chemo- or radiation-induced leukocytopenia, atherosclerosis, and hyperlipidemia.
Resveratrol can be produced from polydatin fermented by Aspergillus oryzae. That's why people call polydatin as the precursor of resveratrol. This latter species produces a piceid-b-D-glucosidase.
Trans-piceid is the glucoside formed with trans-resveratrol, while cis-piceid is formed with cis-resveratrol. Trans-resveratrol-3-O-glucuronide is one of the two metabolites of trans-piceid in rat.
Function of Resveratrol:
1. Anti-cancer
2. Effect on cardiovascular system
3. Antibacterial and antifungal
4. Nourish and protect liver
5. Antioxidant and quench free-radicals
6. Impact on the metabolism of osseous issue
Application of Resveratrol :
1. Applied in food field, it's used as food additive with the function of lengthening life.
2. Applied in pharmaceutical field, it is frequently used as medicine supplement or OTCs ingredients and owns good efficacy for
treatment of cancer and cardio-cerebrovascular disease.
3. Applied in comestics, it can delay aging and prevent UV radiation.
