Effect of geographical origin on the chemical characteristics of Q. canariensis acorns: profiling fatty acids, tocopherols, and phenolic composition
Natural Product Research(2024)
Abstract
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 Q. canariensis acorns. The obtained results revealed that acorn oil from BniMtir exhibited high levels of alpha-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 mu g/g DW) and gallic acids (1.674-10.849 mu g/g DW), as well as catechin (+) (0.096-12.647 mu g/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 Q. canariensis acorns, which could have various applications.
