Actinidia chinensis Planch ferment and use thereof

A method of increasing an antioxidant activity and an anti-glycation activity in a subject in need thereof, comprising administering to the subject in need thereof an effective amount of an Actinidia chinensis Planch ferment, wherein the Actinidia chinensis Planch ferment is obtained by steps of:

• extracting Actinidia chinensis Planch with water to obtain an Actinidia chinensis Planch extract;
• fermenting the Actinidia chinensis Planch extract sequentially with 0.01-0.5% (v/v) of Saccharomyces cerevisiae for 1-2.5 days, 0.01-0.25% (v/v) of Lactobacillus plantarum for 1-3 days, and 3-10% (v/v) of Acetobacter aceti for 3-10 days;
• and
• separating the Actinidia chinensis Planch ferment;
• wherein increasing the antioxidant activity and the anti-glycation activity are determined by comparing to that of the unfermented Actinidia chinensis Planch extract.
