采用毛细管气相色谱法 ,以外标法测定枸橼酸托烷司琼中乙醇、二氯甲烷、氯仿、四氢呋喃、二烷、吡啶和甲苯的含量 ,用串联的 HP- 1(0 .5 3mm× 30 m)和 HP- 5 (0 .5 3mm× 10 m)色谱柱 ,柱温采取程序升温的方法。在本色谱条件下 ,测得各溶剂的线性良好 (相关系数均在 0 .99以上 ) ;平均回收率 85 .7%～ 10 8.1% ;最小检出量 0 .96～2 .8ng。
The content of ethanol, dichloromethane, chloroform, tetrahydrofuran, dioxane, pyridine and toluene in tropicitabine citrate was determined by capillary gas chromatography with external standard method. 30 m) and HP-5 (0 .5 3mm × 10 m) column, the column temperature to take the program temperature. Under the chromatographic conditions, the linearity of each solvent was good (the correlation coefficients were all above 0.99); the average recovery was 85.7% ~10 8.1%; the minimum detectable amount was 0.96 ~ 2.8ng.
