由于多数强心甙安全范围小,治疗量和中毒量接近,在剂量上不易掌握,因而在使用上受到一定限制。许多药物分析化学家长期从事植物强心甙及制剂的定性定量方法的研究,探寻灵敏,快速、准确的分析方法。如先后有纸层,薄层分析法,比色分析法,荧光分析法等,但结果往往不能令人满意,尤其在分析成分复杂的生药时,选择性问题难以克服。由于强心甙挥发性衍生物衍生过程复杂,气相色谱方法进展也较为缓慢,1974年
Because most of the cardiac palatal safety ranges are small, the amount of treatment and the amount of poisoning are close to each other, and it is difficult to grasp the dose, it is limited in use. Many drug analysis chemists have long been engaged in research on the qualitative and quantitative methods of plant cardiac glycosides and preparations, and seek out sensitive, rapid, and accurate analytical methods. For example, paper layer, thin layer analysis method, colorimetric analysis method, fluorescence analysis method, etc. are often used, but the results are often unsatisfactory. Especially when analyzing crude drugs with a complex composition, selectivity problems are difficult to overcome. Due to the complex process of derivatization of volatile derivatives from the palpitations, the development of gas chromatography methods is also slow, 1974.
