Synthetic method for GHK copper peptides

The invention provides a synthetic method for obtaining high-purity GHK copper peptides. According to the method, the post-treatment meanses of complexing GHK tripeptides with a copper complexing agent, performing filtering, preforming rotary drying, performing freeze drying and the like are taken, and high-purity GHK copper peptides can be obtained. The obtained copper complexing agent is selected from one or a mixture of two of copper acetate, copper hydroxide and copper methoxide. The synthetic method mainly has the advantages that compared with a conventional synthetic method, the synthetic method is simpler to operate and lower in cost, application of resins is avoided, the GHK copper peptide products being high in purity, high in yield and qualified and stable in sample parameters can be obtained, and the synthetic method can be applied to mass production. 本发明提供了一种获得高纯度GHK铜肽的合成方法，所述方法为将GHK三肽和铜络合剂相络合，并通过过滤，旋干，冻干等后处理手段，即得所述的高纯度的GHK铜肽。所述的铜络合剂选自下列之一或两种的混合物：醋酸铜，氢氧化铜，二甲醇铜。本发明的优点主要体现在：与以往的合成方法相比，操作简单，成本低廉，避免了树
