本文用超临界流体色谱法(SFC)测定了三七和云南白药中人参二醇及人参三醇的含量。使用15%硫酸乙醇—水(1:1)直接进行水解,然后碱水解,克服了文献报道的水解不完全、结果不稳定、不能定量回收的缺点。本法取样量少,灵敏度高,操作简单、快速、整个分析过程可在8h内完成。
In this paper, the contents of panaxadiol and ginseng triol in Panax notoginseng and Yunnan Baiyao were determined by supercritical fluid chromatography (SFC). The use of 15% sulfuric acid ethanol-water (1:1) for direct hydrolysis followed by alkaline hydrolysis overcomes the disadvantages reported in the literature of incomplete hydrolysis, unstable results, and non-quantitative recovery. This method has a small sample size, high sensitivity, simple operation and rapid operation, and the entire analysis process can be completed within 8 hours.
