摘要
建立了毛细管气相色谱同时测定六神祛暑水中樟脑、薄荷脑含量的方法。樟脑含量在0.04044～0.5055mg/mL范围内线性关系良好(r=0.999 9),测定结果的相对标准偏差为0.79%(n=6),平均回收率为99.18%;薄荷脑含量在0.04984～0.2492 mg/mL范围内线性关系良好(r=0.9994),测定结果的相对标准偏差为1.5%(n=6),平均回收率为99.65%。结果表明,该定量方法精密度好,准确度高,测定简便、快速,可用于制剂的质量控制。
A method for determination of camphor and menthol in Liushen Qushu Shui was established. The linear range of camphor was 0.040 44 - 0. 505 5 mg/mL with a good linear relationship （ r = 0.999 9 ）, and average recovery was 99.18 % , the relative standard deviation was 0.79% （ n = 6）. The hnear range of menthol was 0. 049 84 - 0. 249 2 mg/mL with a good linear relationship（ r = 0. 9994）, and average recovery was 99.65%, the relative standard deviation was 1.5% （ n = 6）. This method is simple, rapid, accu- rate, and it can be used to control the quality of preparation.
