Abstract Nectaroscordum siculum ssp. bulgaricum (Janka) Stearn (Allium siculum subsp. dioscoridis (Sm.) K. Richt.) is a traditional culinary spice from South-East Europe. Studies of N. siculum have focused mainly on the botanical and taxonomic characteristics of this species and there is no data available in the scientific literature about its metabolite profile. Thus, the aim of the current study was metabolite profiling of four wild populations of N. siculum grown in Bulgaria by gas chromatography coupled to mass spectrometry (GC-MS) and subsequent principal component analysis (PCA) of the data obtained. The identified primary metabolites (carbohydrates, amino acids, organic acids and lipids) are initial compounds for the biosynthesis of different plant secondary metabolites, such as polyphenols and flavour compounds with valuable biological activities for humans. The health benefits of the phenolic acids identified in this study have been a prerequisite for the implementation of N. siculum in different food systems in order to increase their quality and biological value.

通过 GC-MS 结合 Nectaroscordum siculum ssp 自然种群的主成分分析进行代谢物分析。保加利亚（Janka）斯特恩

摘要 Nectaroscordum siculum ssp。bulgaricum (Janka) Searn (Allium siculum subsp. dioscoridis (Sm.) K. Richt.) 是一种来自东南欧的传统烹饪香料。对 N. siculum 的研究主要集中在该物种的植物学和分类学特征上，科学文献中没有关于其代谢物谱的数据。因此，本研究的目的是通过气相色谱与质谱联用 (GC-MS) 和随后对获得的数据进行主成分分析 (PCA) 对生长在保加利亚的四个野生 N. siculum 种群进行代谢物分析。已鉴定的初级代谢物（碳水化合物、氨基酸、有机酸和脂质）是不同植物次级代谢物生物合成的初始化合物，例如对人类具有重要生物活性的多酚和风味化合物。本研究中确定的酚酸对健康的益处是在不同食品系统中实施 N. siculum 以提高其质量和生物学价值的先决条件。
