The present work investigated the phenolic profiles, antioxidant activities, and cytoprotective effects of the free, esterified, and insoluble-bound phenolic fractions from oil palm fruits treated under ultra-high pressure (UHP). Results showed that UHP treatment significantly increased the total phenolic and flavonoid contents of all three phenolic fractions (p < 0.05). A total of 11 and 12 phenolic compounds were detected and quantified in non-treated and UHP-treated fruits, with caffeic acid having the highest concentration in insoluble-bound phenolic fractions with 8.68 and 11.27 mg/g of dry extract, respectively. The antioxidant activities, intracellular reactive oxygen species inhibition, and cytoprotective effects of all three phenolic fractions were dramatically enhanced after UHP pretreatment (p < 0.05). Therefore, UHP-treated oil palm fruits with increased bioactivities could be used in functional food or the nutraceutical industry to enhance their applications and economic value.
本研究调查了经超高压（UHP）处理的油棕果实中游离、酯化和不溶性结合酚类部分的酚类谱、抗氧化活性和细胞保护作用。结果表明，UHP 处理显著增加了所有三种酚类部分的总酚和类黄酮含量（p<0.05）。在未经处理和 UHP 处理的果实中检测到并定量了 11 和 12 种酚类化合物，其中咖啡酸在不溶性结合酚类部分中的浓度最高，分别为 8.68 和 11.27mg/g 干提取物。三种酚类部分的抗氧化活性、细胞内活性氧抑制和细胞保护作用在 UHP 预处理后显著增强（p<0.05）。因此，可将生物活性增强的经 UHP 处理的油棕果实用于功能性食品或营养保健品行业，以提高其应用和经济价值。
