CA 2732306

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 rotundifolid) 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.

L'invention concerne une composition s'utilisant comme antioxydant, par exemple comme complément antivieillissement. Cette composition comprend un extrait de marc de muscadine (Vitis rotundifolid) dont la teneur en polyphénols est d'au moins 2% et du resvératrol trans, qui provient d'une source autre que la muscadine et dont la pureté est d'au moins 5%. Dans un exemple, le rapport entre les polyphénols d'extrait de marc de muscadine et le resvératrol trans se situe entre  0,1/1 et 10/1 (en poids), ce qui permet d'obtenir une composition présentant une activité antioxydante. L'invention concerne aussi des procédés de production de compositions antioxydantes. Ces procédés comprennent l'étape consistant à combiner un extrait de marc de muscadine dont la teneur en polyphénols est d'au moins 2% et du resvératrol, ce dernier provenant d'une source autre que la muscadine et présentant une pureté d'au moins 5%, selon un rapport se situant entre 0,1/1 et 10/1 (en poids), afin de former une composition présentant une activité antioxydante.
