Abstract
The present disclosure discloses a preparation method of fatty acid-based VC liposomes, and belongs to the field of pharmaceutical preparations. In the disclosure, a complex of industrial conjugated linoleic acid and other fatty acids with sodium dodecyl sulfate is taken as a capsule material, which is self-assembled to embed vitamin C in an aqueous phase under an acidic condition (pH<7) to form the fatty acid-based vitamin C liposome. The preparation method of the disclosure does not use organic solvents and other substances harmful to the human body, and has the characteristics of safety and health. In addition to VC encapsulation under the acidic condition, the prepared fatty acid-based liposome can play a role in slowly releasing VC.
