The objectives of this research were to determine the phenolic contents, oxygen radical absorbance capacities (ORAC), cellular antioxidant activities (CAA), and antiproliferative capacities of nine oat varieties and four brans in China. Of all varieties, Longyan 3 and Beiyan 1 exhibited the highest total avenanthramides (146.94±7.31 and 120.95±6.66µg/g, respectively) and ORAC values (21.03±0.56 and 21.18±1.45µM Trolox/g, respectively), while Shaotong exhibited the highest total phenolic acids (143.52±9.42µg/g) and CAA values (33.38±1.74µM quercetin/100g). The EC of antiproliferative capacities ranged from 167.31±6.42 to 233.42±21.31mg/mL, with the lowest in Beixiao 8 while the highest in Jinyan 8. ORAC values correlated with avenanthramides while CAA values correlated with phenolic acids. Moreover, phenolic contents, antioxidant properties, and antiproliferative capacities of oat brans was higher than that of corresponding whole oats in most cases.
本研究的目的是测定中国9个燕麦品种和4种麸皮中的酚类含量、氧自由基吸收能力（ORAC）、细胞抗氧化活性（CAA）和抗增殖能力。在所有品种中，龙燕3号和北燕1号的总燕麦酰胺含量最高（分别为146.94±7.31和120.95±6.66µg/g），ORAC值也最高（分别为21.03±0.56和21.18±1.45µM Trolox/g），而昭通的总酚酸含量最高（143.52±9.42µg/g），CAA值最高（33.38±1.74µM槲皮素/100g）。抗增殖能力的EC范围为167.31±6.42至233.42±21.31mg/mL，其中北小8号最低，金燕8号最高。ORAC值与燕麦酰胺相关，而CAA值与酚酸相关。此外，在大多数情况下，燕麦麸皮的酚类含量、抗氧化性能和抗增殖能力均高于相应的全燕麦。
