Abstract

The analysis of natural products is a challenging task, because the investigated matrices are usually complex, relevant compounds are sometimes present in small amounts, and they often show similar structures. Thus only techniques fulfilling high demands with respect to selectivity, versatility, and sensitivity will be suitable for their analysis especially in real-life samples. That SFC is such a technique is shown in this chapter. The number of relevant applications is still on a manageable level; however, analytes successfully studied by SFC range from alkaloids to carotenoids, phenols, anthraquinones, terpenes, and steroids. The described technical variability is impressive and not limited to the mobile or stationary phase only, but also includes detectors like MS, NMR, and FTIR or the hyphenation to GC and UPLC. The analysis of natural products by SFC is an interesting option, whose relevance will definitely increase in the future.
