The present invention relates to a nanoemulsion of resveratrol-phospholipid complex, method for preparing the same and applications thereof. The nanoemulsion comprises: 1 part by weight of resveratrol, 2˜30 parts by weight of phospholipid, and 30˜490 parts by weight of an aqueous solution of polyol with the polyol concentration being 30˜99 percent by weight. The method comprises the steps of: a resveratrol-phospholipid complex being prepared, then the complex being dispersed into the aqueous solution of polyol to form a dispersion, and a nanoemulsion with particle size less than 200 nm being formed by homogenization of the dispersion with a high pressure homogenizer or Microfluidizer homogenizer. The nanoemulsion is miscible with water at any ratio, has high stability and high bioavailability, and thus can be widely used for preparation of cosmetics, pharmaceuticals or healthcare products.
