The quality of garlic is mainly attributed to organosulfur compounds that are the secondary metabolites of certain amino acids. Herein, a sensitive and rapid method for the simultaneous determination of 7 organosulfur compounds and 21 amino acids using ultra-high-performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) was developed. Then the levels of these 28 compounds and allicin in garlic among 242 samples from 6 provinces in China were profiled with multivariate data analysis. The results showed that garlic was rich in organosulfur compounds and could be a good supplement for amino acids. Contents of 29 compounds varied greatly among the provinces. The multivariate data analysis demonstrated two major groups for all samples, indicating that the location has a significant influence on the metabolism of garlic. Besides, the compositional differences of garlic from 6 provinces and correlations for growing conditions and contents of components were also analyzed.
