 The genus Allium includes hundreds of plant species and is regarded as one of the most cultivated vegetables. It is an important source of novel therapeutic compounds known for their beneficial effects on human health; however, there could be differences in content, composition, type, and bioactivity of the phytochemicals found among the Allium plants. The main purpose of this study was to acquire insights on the variation in antioxidant profiles and phenolic content between Allium accessions in different species, as well as between similar species of several varieties. We collected 112 accessions from more than 20 countries, and grew them under similar agronomic conditions. The antioxidant potential was evaluated by using 2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS), 1,1-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and reducing power (RP) assays. The total phenolic content (TPC) was studied using the Folin–Ciocalteu method. TPC varied from 3.43 (accession 199897) to 22.19 (accession 273483) µg gallic acid equivalent/mg dry weight (DW) of the aerial organs of Allium. The antioxidant activity of Allium samples ranged from 4.37 (accession 806595) to 57.46 (accession number 711971) µg Trolox equivalent/mg DW; 0.35 (accession 117246) to 9.53 (accession 711971) µg ascorbic acid equivalents/mg DW; 2.92 (accession 199890) to 21.20 (accession 803493) µgAAE/mg DW; and 0.80 (accession 117260) to 31.13 (accession 803527) µgAAE/mg DW using ABTS, DPPH, FRAP, and RP assays, respectively. Accessions 273483 (A. cepa), 283346 (A. cepa ‘cepa’), and 803527 (unknown species) had the highest TPC, FRAP, and RP values among those tested, while the highest ABTS and DPPH radical scavenging activities were recorded in accession 711971 (A. ramosum). Pearson’s coefficient of correlations indicated that variables (TPC, ABTS, DPPH, FRAP, and RP values) correlated significantly each other, with r-values between 0.585 and 0.894. Principal component analysis plots and hierarchical cluster analysis indicated significant variability in antioxidant activity and phenolic content among all the accessions studied, as well as within similar species. Based on our results from principal component and hierarchical cluster analysis, accession 283346 (A. cepa ‘cepa’), K139348 (A. fistulosum), and 711971 (A. ramosum) are potential sources of phenolics and natural antioxidants. The variability in total phenolic and antioxidant activity among the Allium accessions can be used by breeders, food technologists, nutritionist, and researchers for assessing breeding lines for genetic selection and for monitoring levels of these factors during food storage and processing.
