Little is known about the genetic variability in lutein content for soybeans (Glycine max L.) cultivated in Korea. Therefore, the objective of this study was to screen high quality soybean cultivars for lutein content. The lutein contents of 23 recommended varieties, 56 sauce varieties, 44 sprout varieties, and 40 local varieties were determined by saponification followed by reversed phase high performance liquid chromatography (HPLC). We found that IT No. 153398 and 22789, originating from sauce and local varieties, respectively, contained significantly higher amounts of lutein as compared to the other 161 samples. Moreover, relevant quantitative differences were found among the samples, which had lutein contents ranging from 83 to 402 μg/100 g in the recommended varieties, from 39 to 778 μg/100 g in the sauce varieties, from 52 to 589 μg/100 g in the sprout varieties, and from 106 to 861 μg/100 g in the local varieties, respectively. In summary, this study provides reliable lutein data for soybean cultivars that can be used for breeding studies and the development of functional foods.
