Abstract： Gas chromatography-mass spectrum (GC-MS) and high pressure liquid chromatography (HPLC) are the two techniques most frequently used in research on chemical ecology. Drawing on the authors’ experiences, this paper discusses key points related to sample preparation, the principles of GC-MS and HPLC, how to select techniques for chemical analysis, the qualification and quantification of samples, and describes and discusses some examples in detail.
