本文建立了反相、正相高效液相色谱和气相色谱两种分析方法，并对两种方法进行了比较。通过所有的方法，这些化合物都可以得到令人满意的分离。每种方法在分离质量、时间或条件方面都比以前发表的方法有明显的优势。用这些新方法和改进的方法对几个卡瓦样品进行了分析，所得的定性和定量结果具有可比性。观察了分离时间和检出限的主要差异，因此根据要求，每种方法可能是优选的。
The development and comparison of two analytical methods (HPLC in reversed phase and normal phase mode and GC) for the determination of six major lactones in P. methysticum is described in this paper. By all methods, a satisfying separation of these compounds could be achieved. Each method shows distinct advantages to previously published ones, regarding separation quality, time or conditions. Several kava samples were analyzed by these new or modified methods, and the qualitative and quantitative results obtained were comparable. Primary differences in separation times and detection limits were observed, so that each method might be preferable, depending on the requirements.
