Comparison of Lipid-Related Compounds in Wheat Cultivars and Their Physiological Activities

Abstract

We investigated the lipid components in ten wheat cultivars and their physiological activities. The crude lipid contents of wheat cultivars varied from 1.42 to 2.35%. The α-tocopherol content of 'Ofri' (9.15 μg/g) and the β-tocopherol content of 'Baekchal' (4.19 μg/g) were higher than that in other cultivars. γ-Tocopherol contents of 'Baekchal', 'Saegeumgang', and 'Hwanggeumal' were 0.23, 0.19, and 0.23 μg/g, respectively, but it was not detected in any other cultivar. α-Tocotrienol content was highest in 'Baekkang' (3.83 μg/g), and β-tocotrienol contents ranged from 12.42 to 17.24 μg/g and were also highest in 'Baekkang'. β-Sitosterol and campesterol contents were higher in 'Goso ' (2,527.18 and 284.72 ppm, respectively) than in other cultivars. DPPH radical scavenging activities ranged from 2.41 to 4.26 mg TE/g, and 'Jokyoung' had the highest level. 'Baekchal' had greatest tyrosinase inhibitory activity (50.62∼69.60%). The study provides basic information on the functional properties of wheat cultivar lipids and will aid the utilization of wheat as a raw material for cosmetic industries.
