Embodiment 1
[0033] A method for measuring the characteristic spectrum of Xiaoshuan Tongluo granules, which adopts high performance liquid chromatography, and its chromatographic conditions include: the chromatographic column is an octylsilane bonded silica gel chromatographic column (250 × 4.6mm, 5 μm), and the mass fraction is 0.08wt% phosphoric acid aqueous solution was used as mobile phase A, acetonitrile mobile phase B was used, the detection wavelength was 262nm, the flow rate was 0.9ml / min, and the column temperature was 35°C for gradient elution;
[0034] The gradient elution process is: within 0-20min, the volume ratio of mobile phase A and mobile phase B changes gradually from 85:15 to 80:20 at a uniform speed; within 20-30min, the volume ratio of mobile phase A and mobile phase B changes from From 80:20 to 65:35 at a constant speed; within 30-45min, the volume ratio of mobile phase A and mobile phase B changes from 65:35 to 55:45 at a constant speed; within 45-50min, the volume o...
