本文用103型气相层析仪,经改装后作毛细管气相色谱,用国产SE-30玻璃毛细管柱,以正十三烷为内标,分离测定了合成冰片及几种含冰片中成药中龙脑和异龙脑的含量。本法样品处理简便,所测中成药处方中共存组分无干扰。龙脑检测限为5.28×10~(-10)克/秒。异龙脑检测限为6.11×10~(-10)克/秒,龙脑与异龙脑的平均回收率分别为101.0±0.65%和100.3±0.65%。 In this paper, 103 gas chromatograph was used for the analysis of capillary gas chromatography. SE-30 glass capillary column made in China and n-tridecane as the internal standard were used to separate and determine synthetic borneol and several borneol Chinese patent medicines. And isoborneol content. The sample of this method is easy to handle, and there is no interference in the coexistent components of the Chinese medicine prescription. The brain detection limit is 5.28×10 -10 g/sec. The allo-brain detection limit was 6.11×10 −10 g/s, and the average recovery rates of borneol and allosaurine were 101.0±0.65% and 100.3±0.65%, respectively.
