建立了一种准确测定水溶液中榄香烯哌啶盐含量的方法。样品水溶液经碳酸钠中和 ,并用含正十八烷(内标 )的正庚烷溶液萃取后 ,采用毛细管气相色谱法进行分析。方法的线性范围为 1 0 g/L～ 1 0 0 g/L ,精密度小于 2 % ,平均回收率为 99 96% ,RSD为 0 46% (n =5)。 A method for the accurate determination of elemene salt in aqueous solution was established. The aqueous sample was neutralized with sodium carbonate and extracted with n-heptane containing n-octadecane (internal standard), followed by capillary gas chromatography. The linear range of the method was 10 g / L ~ 100 g / L, the precision was less than 2%, the average recovery was 99.96% and RSD was 46% (n = 5).
