本文建立的HPLC测定条件是以Perkin-Elmer硅胶柱(250×3.9mm,id)为色谱柱,乙酸乙酯-甲酸-无水乙醇(15:3:2)为流动相,流速1.5 ml
The HPLC conditions established in this paper were determined on a Perkin-Elmer silica gel column (250×3.9 mm, id) with a mobile phase of ethyl acetate-formic acid-anhydrous ethanol (15:3:2) at a flow rate of 1.5 ml.
