Eleven fatty acids were identified during maturity in the wild (AraA) and varieties peanut kernels (AraC and AraT). These fatty acids included C (palmitic acid), C (stearic acid), C (oleic acid), C (linoleic acid), C (nonadecanoic acid), C (gadoleic acid), C (arachidic acid), C (erucic acid), C (behenic acid), C (tricosanoic acid) and C (linoceric acid). Two fatty acids C and C were not previously detected from peanut kernels. Furthermore, eight major fatty acids (C, C, C, C, C, C, C and C) were quantified during maturity. Wild AraA was distinguished by its highest level of oleic (38.72%) and stearic (2.63%) acids contents and the lowest one of linoleic acid (19.40%) compared to the varieties. As for the O/L ratio, wild AraA presents a significantly higher (p < 0.05) (O/L = 2) than that of the AraC and AraT varieties with (O/L = 1.7 and 1.04) respectively. Correlation coefficients (r) between the eight major fatty acids revealed an inverse association between oleic and linoleic acids (r = -0.99, p < 0.001), while linoleic acid was positively correlated to palmitic acid (r = 0.97). These results aim to provide a detailed basis for quality improvement in the cultivated peanut with wild resources.
在野生（AraA）和栽培花生品种（AraC 和 AraT）仁中鉴定出 11 种脂肪酸。这些脂肪酸包括 C（棕榈酸）、C（硬脂酸）、C（油酸）、C（亚油酸）、C（正十九烷酸）、C（花生酸）、C（山嵛酸）、C（二十碳烯酸）、C（芥酸）、C（木蜡酸）、C（二十三烷酸）和 C（亚麻酸）。此前从未从花生仁中检测到 C 和 C 两种脂肪酸。此外，在成熟过程中定量了八种主要脂肪酸（C、C、C、C、C、C、C 和 C）。野生 AraA 的油酸（38.72%）和硬脂酸（2.63%）含量最高，亚油酸（19.40%）含量最低，与品种不同。就 O/L 比值而言，野生 AraA 明显更高（p < 0.05）（O/L = 2），而 AraC 和 AraT 品种的 O/L 比值分别为 1.7 和 1.04。八种主要脂肪酸之间的相关系数（r）表明，油酸和亚油酸之间呈负相关（r = -0.99，p < 0.001），而亚油酸与棕榈酸呈正相关（r = 0.97）。这些结果旨在为利用野生资源改良栽培花生的品质提供详细的基础。
