Abstract

BACKGROUND This study compares the composition of fatty acid methyl esters (FAMEs) in seeds of Sesbania speciosa (dry and mature) after processing (uncooked and cooked) and extraction (hot and cold). METHODS Among PUFA, oleic, linoleic and linolenic acids were common to uncooked and cooked dry seeds which were high on cold extraction. Only two fatty acid ratios were favorable in hot extraction [(C14:0 + C15:0 + (C16:0 / C18:0) and C18:1 / C18:2]. RESULTS Cold extraction yielded docosahexaenoic acid in uncooked as well as cooked dry seeds and all fatty acid ratios were nutritionally favorable. In mature seeds, lauric and myristic acids were high on hot extraction, while palmitic and stearic acids were high on cold extraction. Except for ω-6/ω-3 ratio, the rest fatty acid ratios in mature seeds on hot extraction were not favorable, while cold extraction resulted in three favorable ratios (TUFA/TSFA, TPUFA/TMUFA and ω-6/ω-3). Three-way ANOVA on the impact of seeds, process and extraction of major fatty acids revealed significant difference only between extraction methods (p < 0.001). CONCLUSION Overall, the cold extraction for dry as well as mature seeds were advantageous for essential fatty acids profile. Some of the recent patents are dealing with antineoplastic compounds as well as radioprotective drugs derived from Sesbania speciosa.
印度西南部红树野生豆科种子(Sesbania speciosa)脂肪酸组成。
本研究比较了芝麻籽(干燥和成熟)加工(生、熟)和提取(热、冷)后脂肪酸甲酯(FAMEs)的组成。方法多聚脂肪酸中油酸、亚油酸和亚麻酸在生、熟干种子中普遍存在,冷提率较高。只有两种脂肪酸配比有利于热提[(C14:0 + C15:0 + (C16:0 / C18:0)和C18:1 / C18:2]。结果三种脂肪酸提取法均能有效地提取出二碳六烯酸,且各脂肪酸比例均较好。在成熟种子中,热萃取时月桂酸和肉豆蔻酸含量高,冷萃取时棕榈酸和硬脂酸含量高。成熟种子中除ω-6/ω-3比值外,其余脂肪酸比值在热提取条件下均不有利,冷提取条件下有3个脂肪酸比值(TUFA/TSFA、TPUFA/TMUFA和ω-6/ω-3)有利。对种子、工艺和主要脂肪酸提取方法影响的三因素方差分析显示,只有提取方法之间存在显著差异(p < 0.001)。结论干燥种子和成熟种子冷提取均有利于提取必需脂肪酸。最近的一些专利涉及从田菁中提取的抗肿瘤化合物和辐射防护药物。
