采用正十二烷作内标，选用ＯＶ－１０１的石英玻璃毛细管柱，建立了某药厂中成药胶囊中冰片含量的气相色谱测定方法。与张亮（１９９４）、刘柏年（１９８４）工作相比，不仅大大节约了分析时间，而且分离效果更佳，测定结果的重现性好，标准偏差Ｓ＝０．４０，平均回收率高达９９．０％，内标物与冰片的浓度比为１∶０．３～１∶１．５时峰面积与浓度成线性关系，相关系数ｒ＝０．９９９７。
Using n-dodecane as internal standard, OV-101 quartz glass capillary column was used to determine the content of borneol in a Chinese medicine capsule by gas chromatography. Compared with the work of Zhang Liang (1994) and Liu Bainian (1984), not only the analysis time is greatly saved, but also the separation effect is better. The reproducibility of the determination results is good. The standard deviation S = 0.40 and the average recovery rate are as high as 99%. 0%, the internal standard and borneol concentration ratio of 1: 0.3 ~ 1: 1.5 peak area and concentration of a linear relationship, the correlation coefficient r = 0.9997.
