摘要：GS-MS based metabolite profile of fenugreek (Trigonella foenum-graecum L.) of three different trademarks was investigated. In polar fractions totally 40 primary metabolites (carbohydrates, organic and amino acids) and 9 phenolic acids (with caffeic and 4-hydroxybenzoic acids as major) were identified. The dominant metabolites in non-polar fraction were palmitic, linoleic, oleic and stearic acids. Two untypical triterpenic acids (oleanolic and ursolic acid) for family Fabaceae were identified in one of the analyzed sample. The presence of these triterpenoids in the sample of fenugreek indicates for probably adulteration, during the production process, with spices from other families, such as Lamiaceae or Rosaceae. The data of provided GC-MS analyses and subsequent principal component analysis (PCA) and hierarchical cluster analysis (HCA) revealed that investigated samples of the same species from three different trademarks had significant differences in their phytochemical content. Thus could be base for developing a protocol for quality control based on metabolomics approach
