Nowadays, data concerning the composition of Caryodendron orinocense Karst. (Euphorbiaceae) and Bactris gasipaes Kunth (Arecaceae) seed oils are lacking. In light of this fact, in this paper fatty acids and unsaponifiable fraction composition have been determined using GC-MS, HPLC-DAD (Diode Array Detector), NMR approaches and possible future applications have been preliminary investigated through estimation of antioxidant activity, performed with DPPH test. For C. orinocense linoleic acid (85.59%) was the main component, lauric (33.29%) and myristic (27.76%) acids were instead the most abundant in B. gasipaes. C. orinocense unsaponifiable fraction (8.06%) evidenced a remarkable content of β-sitosterol, campesterol, stigmasterol, squalene and vitamin E (816 ppm). B. gasipaes revealed instead β-sitosterol and squalene as main constituents of unsaponifiable matter (3.01%). Antioxidant capacity evidenced the best performance of C. orinocense seed oil. These preliminary results could be interesting to suggest the improvement of the population's incomes from Amazonian basin. In particular the knowledge of chemical composition of C. orinocense and B. gasipaes oils could be helpful to divulge and valorize these autochthones plants.
目前，关于奥里诺科嘉宝树（大戟科）和圭亚那棕（棕榈科）种子油成分的数据尚缺。鉴于此，本文采用气相色谱 - 质谱联用（GC-MS）、高效液相色谱 - 二极管阵列检测（HPLC-DAD）、核磁共振（NMR）方法测定了脂肪酸和不皂化物成分，并通过DPPH试验评估抗氧化活性对其可能的未来应用进行了初步研究。对于奥里诺科嘉宝树，亚油酸（85.59%）是主要成分，而在圭亚那棕中月桂酸（33.29%）和肉豆蔻酸（27.76%）含量最高。奥里诺科嘉宝树的不皂化物部分（8.06%）显示出β-谷甾醇、菜油甾醇、豆甾醇、角鲨烯和维生素E（816 ppm）的含量显著。相反，圭亚那棕的不皂化物主要成分是β-谷甾醇和角鲨烯（3.01%）。抗氧化能力表明奥里诺科嘉宝树种子油性能最佳。这些初步结果可能有助于提高亚马逊河流域居民的收入。特别是对奥里诺科嘉宝树和圭亚那棕油化学成分的了解，可能有助于推广和提升这些本土植物的价值。
