Samples of belladonna pilular and powdered extract and tincture from two suppliers were analyzed by GLC as a cooperative effort between two laboratories to develop methodology with substantial improvements in sensitivity, specificity, precision, and working time over the present official method. This goal was achieved, but marked differences in response of the individual extracts to different isolation schemes were noted.
作为两个实验室的合作项目，对来自两个供应商的颠茄丸剂、粉末提取物和酊剂样本进行了气相色谱分析，旨在开发一种在灵敏度、特异性、精密度和工作时间方面比现行官方方法有显著改进的方法。这一目标得以实现，但注意到各个提取物对不同分离方案的响应存在显著差异。
