The current study investigated the effect of developmental stages on the chemical composition and the antioxidant activity of fifteen crude oil samples obtained from Pistacia atlantica Desf. leaves, galls, and fruits. Twelve fatty acids were detected by GC/FID, linolenic acid (C18 : 3) was the major fatty acid detected in leaves crude oils that registered [41.73 % (P<0.05)] on the last stage. The best content of tocopherols and carotenoids was recorded at the last stage for leaves and galls oils, respectively, with values of [1.530±0.01, 0.52±0.01 (P<0.05) mg α‐tocopherol equivalent/g DW] and [86.60±0.95, 69.15±0.13 (P<0.05) μg β‐carotene equivalent/g DW]. For fruits oils, the content varied depending on the levels of fruits maturation. The results from DPPH, FRAP, and ABTS assays revealed that the antioxidant activity increased with the increasing content of tocopherols and carotenoids in leaves and galls oils during development stages, and varied for fruits oils depending on the ripening stages. Moreover, according to PCA analysis, the best phytoconstituent content and antioxidant activity were attributed to P. atlantica Desf. fruit's crude oils. Also, a strong relationship was found between the antioxidant activity and bioactive phytochemical components, such as tocopherols, carotenoids, and omega‐three fatty acid, which confirmed that P. atlantica Desf. crude oils present a valuable source of natural antioxidant that could be used for pharmaceutical and food industries purposes.

总生育酚、类胡萝卜素和脂肪酸含量的变化 大西洋黄连木 不同器官原油及其在发育阶段的抗氧化活性。

目前的研究调查了发育阶段对从 Pistacia atlantica Desf 中获得的 15 份原油样品的化学成分和抗氧化活性的影响。叶、瘿和果实。GC/FID 检测到12 种脂肪酸,亚麻酸(C18 : 3)是在最后阶段登记[41.73 % (P<0.05)] 的叶原油中检测到的主要脂肪酸。叶和瘿油的生育酚和类胡萝卜素含量最高,分别为 [1.530±0.01, 0.52±0.01 (P<0.05) mg α-生育酚当量/g DW] 和 [86.60± 0.95, 69.15±0.13 (P<0.05) μg β-胡萝卜素当量/g DW]。对于果油,其含量因果实成熟程度而异。DPPH、FRAP 的结果,和 ABTS 分析表明,在发育阶段,抗氧化活性随着叶子和瘿油中生育酚和类胡萝卜素含量的增加而增加,并且根据成熟阶段的不同,果油的抗氧化活性也有所不同。此外,根据 PCA 分析,最好的植物成分含量和抗氧化活性归因于 P. atlantica Desf。水果的原油。此外,还发现抗氧化活性与生物活性植物化学成分(如生育酚、类胡萝卜素和 omega-3 脂肪酸)之间存在密切关系,这证实了 P. atlantica Desf. 原油是一种宝贵的天然抗氧化剂来源,可用于制药和食品工业。果油因成熟阶段而异。此外,根据 PCA 分析,最好的植物成分含量和抗氧化活性归因于 P. atlantica Desf。水果的原油。此外,还发现抗氧化活性与生物活性植物化学成分(如生育酚、类胡萝卜素和 omega-3 脂肪酸)之间存在密切关系,这证实了 P. atlantica Desf. 原油是一种宝贵的天然抗氧化剂来源,可用于制药和食品工业。果油因成熟阶段而异。此外,根据 PCA 分析,最好的植物成分含量和抗氧化活性归因于 P. atlantica Desf。水果的原油。此外,还发现抗氧化活性与生物活性植物化学成分(如生育酚、类胡萝卜素和 omega-3 脂肪酸)之间存在密切关系,这证实了 P. atlantica Desf. 原油是一种宝贵的天然抗氧化剂来源,可用于制药和食品工业。发现抗氧化活性与生物活性植物化学成分(如生育酚、类胡萝卜素和 omega-3 脂肪酸)之间存在密切关系,这证实了 P. atlantica Desf. 原油是一种宝贵的天然抗氧化剂来源,可用于制药和食品工业。发现抗氧化活性与生物活性植物化学成分(如生育酚、类胡萝卜素和 omega-3 脂肪酸)之间存在密切关系,这证实了 P. atlantica Desf. 原油是一种宝贵的天然抗氧化剂来源,可用于制药和食品工业。
