The impact of geographical origin on the chemical composition of acorns from Quercus species has significant attention. This study aimed to explore the phenolic composition of methanolic extracts, tocopherol content, and fatty acid composition of acorn oils from six different populations of acorns. The obtained results revealed that acorn oil from BniMtir exhibited high levels of α-tocopherol (58 mg/kg). The fatty acids identified across all samples were Z-vaccenic + oleic acids (38.44-58.58%). In addition, the data highlighted the presence of quinic (32.514-60.216 µg/g DW) and gallic acids (1.674-10.849 µg/g DW), as well as catechin (+) (0.096-12.647 µg/g DW) in all populations. These variations in chemical composition from different regions are likely linked to their geographical origin. In conclusion, this study's finding should significance for the industry, offering valuable insights into the potential production of bioactive compounds from acorns, which could have various applications.
栎属物种橡子的地理来源对其化学成分的影响受到了广泛关注。本研究旨在探究来自六个不同种群橡子的甲醇提取物的酚类成分、生育酚含量以及橡子油的脂肪酸组成。所得结果显示，来自布尼姆蒂尔的橡子油中α-生育酚含量较高（58毫克/千克）。所有样品中鉴定出的脂肪酸为反式vaccenic酸+油酸（38.44 - 58.58%）。此外，数据还表明所有种群中均存在奎尼酸（32.514 - 60.216微克/克干重）、没食子酸（1.674 - 10.849微克/克干重）以及儿茶素（+）（0.096 - 12.647微克/克干重）。不同地区化学成分的这些差异可能与其地理来源有关。总之，本研究的发现对该行业具有重要意义，为从橡子中生产生物活性化合物的潜在应用提供了有价值的见解，这些生物活性化合物可能有多种用途。
