Method for testing content of index component in Siweizhenceng ice boron eye drop

The invention discloses a method for testing contents of characteristic components, namely oligopeptide-L-tyrosyl glycine and L-tryptophan in a Siweizhenceng ice boron eye drop. The method is characterized by comprising the following steps: performing separation purification and structure identification on a Siweizhenceng ice boron eye drop, confirming seven monomer compounds including oligopeptide-L-tyrosyl glycine and L-tryptophan as characteristic components of the Siweizhenceng ice boron eye drop, and testing the contents of oligopeptide-L-tyrosyl glycine and L-tryptophan in the Siweizhenceng ice boron eye drop by using an HPLC (High Performance Liquid Chromatography) method. By controlling the contents of the characteristic components, namely oligopeptide-L-tyrosyl glycine and L-tryptophan, the quality stability uniformity of the Siweizhenceng ice boron eye drop can be ensured, and the quality controllability of the product is improved. The method is simple, convenient and rapid,good in specificity and c
