Embodiment 3
[0115] The content determination of embodiment three batches of test samples
[0116] 1. Determination of the test product
[0117] Dima C 18 Column (5μm, 4.6mm×250mm); with octadecylsilane bonded silica gel as filler; with 0.017% formic acid solution as mobile phase A, with methanol-acetonitrile (30:10) as mobile phase B, press The gradient elution is specified in the table; the flow rate is 1ml per minute; the detection wavelength is 286nm; the column temperature is 30°C. The number of theoretical plates should not be less than 4000 based on the peak of salvianolic acid B. See the table below for the elution method.
