摘要

Abstract >An on‐line supercritical fluid extraction coupled with supercritical fluid chromatography method was developed for the determination of four major aromatic constituents in vanilla. The parameters of supercritical fluid extraction were systematically investigated using single factor optimization experiments and response surface methodology by a Box–Behnken design. The modifier ratio, split ratio, and the extraction temperature and pressure were the major parameters which have significant effects on the extraction. While the static extraction time, dynamic extraction time, and recycle time had little influence on the compounds with low polarity. Under the optimized conditions, the relative extraction efficiencies of all the constituents reached 89.0–95.1%. The limits of quantification were in the range of 1.123–4.747?μg. The limits of detection were in the range of 0.3368–1.424?μg. The recoveries of the four analytes were in the range of 76.1–88.9%. The relative standard deviations of intra‐ and interday precision ranged from 4.2 to 7.6%. Compared with other off‐line methods, the present method obtained higher extraction yields for all four aromatic constituents. Finally, this method has been applied to the analysis of vanilla from different sources. On the basis of the results, the on‐line supercritical fluid extraction‐supercritical fluid chromatography method shows great promise in the analysis of aromatic constituents in natural products.

>与超临界流体色谱法一起耦合的在线超临界流体提取以确定香草中的四个主要芳香成分。通过单因素优化实验和响应面方法通过Box-Behnken设计系统地研究了超临界流体提取的参数。改性剂比，分流比和提取温度和压力是对萃取产生显着影响的主要参数。虽然静态提取时间，动态提取时间和再循环时间对具有低极性的化合物几乎没有影响。在优化的条件下，所有成分的相对提取效率达到89.0-95.1％。定量极限范围为1.123-4.747ΩΩΩ·€。检测限为0.3368-1.424≤μg。四种分析物的回收率在76.1-88.9％的范围内。内部和中间精度的相对标准偏差范围为4.2％至7.6％。与其他离线方法相比，本方法为所有四种芳族成分获得了更高的提取产率。最后，该方法已应用于来自不同来源的香草的分析。在结果的基础上，在线超临界流体萃取
