Muscadine compositions with improved anti-oxidant activity

摘要

Disclosed is a composition for use as an antioxidant, such as for use as an anti-aging supplement. The composition can include a muscadine (Vitis rotundifolia) pomace extract having a polyphenol content of at least 2% and trans-resveratrol from a source other than muscadine with a minimum purity of at least 5%. In an example, the ratio of muscadine pomace extract polyphenols to trans-resveratrol is in the range of 0.1/1 to 10/1 (weight to weight), thereby providing a composition with antioxidant activity. Also disclosed are methods of producing antioxidant compositions. These methods can include combining a muscadine pomace extract having a polyphenol content of at least 2% and resveratrol from a source other than muscadine with a minimum purity of at least 5% at a ratio in the range of 0.1/1 to 10/1 (weight to weight), thereby providing a composition with antioxidant activity.
