Determination method of attaching Ma Gan pharmaceutical Diester

The present invention provides a method for the determination of Diester an attachment Ma Gan drug was determined by high performance liquid chromatography, which column octadecylsilane bonded silica as filler; acetonitrile - mobile tetrahydrofuran phase A, a solution of phosphoric acid (potassium dihydrogen phosphate-containing) as mobile phase B, a gradient time program, using the reference sample mixing was measured and target component separation, peak shape, tailing factor both a significant improvement, and the specificity, linearity, limit of detection, durability were good.
