Method for mutual transformation of rubrofusarin gentiobioside and heterogeneous rubrofusarin gentiobioside

The invention discloses a method for mutual transformation of rubrofusarin gentiobioside and heterogeneous rubrofusarin gentiobioside. The method comprises preparing a reference solution and a test solution and performing conversion identification. The reference solution is prepared by adding methanol into two 25mL bottles respectively and contains 0.4040mg of rubrofusarin gentiobioside and 0.3928mg of heterogeneous rubrofusarin gentiobioside per 1mL. 0.1mL of the reference solution of rubrofusarin gentiobioside and heterogeneous rubrofusarin gentiobioside is taken respectively to be placed in the 25mL bottles, a solvent is dried, and 10mL of water is added respectively, and the two test solutions are obtained through filtration. 20mL of the reference solution is taken respectively and is injected into a liquid phase with an acetonitrile mobile phase: 0.1% of phosphoric acid=20:80, mutual transformation of rubrofusarin gentiobioside and heterogeneous rubrofusarin gentiobioside can be identified under the colo
