Abstract

Colombian Caribbean avocados (CCA) represent a newly identified genetic group with underexplored bioactive potential. This study compares three CCA landraces─Leche (L), Cebo (C), and Manteco (M)─from northern Colombia to the Hass variety. Comprehensive analyses were conducted on the mesocarp lipid fraction to evaluate oil content (OC), fatty acids (FA) (GC-FID), carotenoids (HPLC-DAD), and untargeted metabolites (UPLC-ESI⁺/Orbitrap-MS) in defatted tissue. Although Hass had higher fat content, FA profiles were similar. CCA showed significantly greater carotenoid levels, especially β-cryptoxanthin, trans-β-apo-8′-apocarotenal, and epoxy-β-carotene. PLS-DA modeling revealed key discriminant compounds, including acetogenins─avocadyne, avocadoes, AcO-avocadenyne, and AcO-avocadiene B─in CCA, while persin appeared only in Hass. These findings underscore the chemical uniqueness and potential of CCA for food and industrial applications.

哥伦比亚加勒比鳄梨和海斯鳄梨生物活性化合物的比较分析：探索代谢组学多样性

哥伦比亚加勒比鳄梨（CCA）代表了一个新发现的遗传群体，其生物活性潜力尚未得到充分开发。本研究比较了哥伦比亚北部的三种CCA地方品种──Leche（左）、Cebo (C)和Manteco (M)──和Hass品种。对中果皮脂质组分进行综合分析，以评估脱脂组织中的油含量（OC）、脂肪酸（FA）（GC-FID）、类胡萝卜素（HPLC-DAD）和非靶向代谢物（UPLC-ESI+/Orbitrap-MS）。虽然哈斯的脂肪含量较高，但FA谱相似。CCA的类胡萝卜素含量显著高于β-隐黄质、反式β-apo-8′- apocrotenal和环氧-β-胡萝卜素。PLS-DA模型揭示了CCA中关键的判别化合物，包括牛油果苷、牛油果、aco -牛油果苷和aco -牛油果苷B，而person只出现在Hass中。这些发现强调了CCA在食品和工业应用中的化学独特性和潜力。
