【 摘 要 】

The vitamin E, total phenolic content (TPC), and antioxidant activity (AA) profiles of 32 whole wheat cultivars were investigated. Samples were classified based on its hardness (HW: hard wheat, MW: medium wheat, and SW: soft wheat) for easy identification. Total vitamin E content ranged from 64.38SW2 to 111.83MW9 mg/kg; α-tocopherol (6.03MW13 to 21.98MW2 mg/kg), β-T (2.14MW8 to 21.01MW9 mg/kg), α-tocotrienol (4.28MW12 to 9.34MW9 mg/kg), and β-T3 (38.71MW16 to 61.07MW9 mg/kg) were the predominant homologs, with β-T3 as the highest. AA ranged from 334.40MW4 to 584.80HW4 μmol gallic acid equivalent/kg while TPC varied from 1139.70SW6 to 2772.60MW1 μmol GAE/kg. Significant differences in the vitamin E content, TPC, and AA were found among the cultivars regardless of its hardness index. A very weak correlation was found between TPC and AA while a moderate negative correlation was observed between vitamin E content and AA. Results from this study can serve as basis of further studies on the bioactive profiles of Korean wheat cultivars.
