The invention relates to an extract product capable of preventing oxidation, delaying aging, and nourishing heart and cerebral vessels, and a preparation method thereof. According to the preparation method, a
grape extract and a mixed fruit
powder are prepared firstly, and are mixed with
yeast for
fermentation, after
metabolism of
yeast, organic conversion of
resveratrol in the
grape extract, andanthocyanidin and a plurality of trace elements in the mixed fruit
powder is realized, so that adsorption on nutrients is improved, and the
biological value is increased. It is confirmed by animal experiments that the extract product is capable of prolonging mouse
life time and rat loaded swimming time obviously, reducing
blood urea nitrogen content, reducing
blood lactic acid accumulation, and increasing
hepatic glycogen content, possesses obvious anti-fatigue activity, is capable of increasing the activity of
superoxide dismutase in rat serum, and accelerating malonaldehyde removing rate, and possesses obvious anti-
oxidation activity. The extract product is prepared from pure natural materials, no chemical
raw material is added, no toxic or
side effect is caused by long term eating. Theextract product is suitable for fatigable people, people high in
