摘要
首次建立了高效液相色谱测定40％乙烯利中6-苄氨基嘌呤含量的方法。色谱柱为Symmetry C18（150mm×3．9mm×5μm）；流动相为甲醇-水（V／V=50：50）；流速为0．8mL／min；线性回归方程为y=9．35×10^6x-3．52×10^3，r=0．9998，线性范围为32．9～411μg；加标回收率平均值为98．2％，RSD为1．42％。
A method for determining the content of 6-benzy- laminopurine in ethephon by HPLC was established for the first time. The column selected was waters symmetry C18（ 150mm×3.9mm×5μm） ; methanol-water mixture （50 ： 50, v/v） was used as the mobile phase;the flow rate was 0.8 mL/min and the detection wavelength was 270 nm. The hnear equation was： y=9.35×10^6x-3.52×10^3,（r=0.9998）.The linear range for detection of 6-benzylaminopurine was 32.9μg～411μg（ r = 0.999 8 ）. The average recovery of 6-benzylaminopurine was 98.2% with RSD= 1.42%.
