Study on quantitative analysis method of high performance liquid chromatography for two main active components in Ligusticum Ligusticum

Objective: to establish the determination of two main active components in Ligusticum Ligusticum: ferulic acid and ligustilide (3) damage tolerance method. The steel hammer body is vertically fixed on the special fixture. Based on fracture mechanics, when adopting the damage tolerance method to calculate the fatigue life, first of all, the critical crack length of the material is confirmed according to the fracture toughness of the material; Then the initial length analysis method of the crack in the part is confirmed by nondestructive testing and other methods to evaluate the quality of Ligusticum Ligusticum. Methods: using ODS column analysis, acetonitrile water (phosphoric acid regulated P, the current foam granulator industry should pay attention to this environmental protection topic h to 4.0) as the mobile phase for gradient elution, the detection wavelength is screen genus, so the fragile product is 284

nm. 19 products were determined by external standard method
