Description
Resveratrol is a natural antioxidant present in plants, Resveratrol is extracted from dried rhizome of polygonum cuspidatum. Resveratrol is off-white (50%) to white powder (98%), soluble in ethanol (50 mg/mL), DMSO (16 mg/mL), and other organic solvents, hardly soluble in water (3 mg/100mL). It mainly exerts its antioxidant effect by scavenging or inhibiting the generation of free radicals, inhibiting lipid peroxidation, and regulating the activity of antioxidant-related enzymes.
Resveratrol generally exists in the trans form in nature, which is theoretically more stable than the cis form. The efficacy of resveratrol mainly comes from its trans structure. Resveratrol is in great demand in the market. Because of its low content in plants and high extraction costs, the use of chemical methods to synthesize resveratrol has become the main means of its development.
MEETSUPPLEMENT can provide natural Polygonum cuspidatum extract resveratrol 98%, 50%, synthetic resveratrol 99% and water-soluble 10%.
