Abstract

In the search for compounds with nutritional and functional value, seeds from several Neltuma species were examined for lipid, protein and phenolic components. Lipid contents ranged between 9.3 and 12.5 g/100 g (seed dry weight), and showed both oleic and linoleic acids predominating largely. Lipids were also a good source of tocopherols (170–603 mg total tocopherols/kg). Proteins accounted for 14.7–35.5 g/100 g seed. Essential amino acids (EAA) comprised 26.1%–40.2% of the total AA content. Based on the EAA score, proteins from all the species analyzed were deficient in leucine, isoleucine and valine, but could meet requirements for histidine, threonine, phenylalanine, tyrosine, and lysine. The qualitative patterns of phenolic compounds were similar each other (predominance of flavonoids, particularly apigenin derivatives). Keeping in mind the examined chemical components, Neltuma seeds have potential value as a source of healthy macronutrients and bioactive compounds.

莕菜种子中的营养成分和生物活性化合物

为了寻找具有营养和功能价值的化合物，研究人员对几种 Neltuma 种子的脂质、蛋白质和酚类成分进行了检测。脂质含量介于 9.3 和 12.5 克/100 克（种子干重）之间，主要以油酸和亚油酸为主。脂质也是生育酚的良好来源（170-603 毫克总生育酚/千克）。蛋白质占 14.7-35.5 克/100 克种子。必需氨基酸（EAA）占 AA 总含量的 26.1%-40.2%。根据 EAA 评分，所有分析物种的蛋白质都缺乏亮氨酸、异亮氨酸和缬氨酸，但组氨酸、苏氨酸、苯丙氨酸、酪氨酸和赖氨酸可以满足需要。酚类化合物的定性模式彼此相似（主要是黄酮类化合物，特别是芹菜素衍生物）。考虑到所研究的化学成分，Neltuma 种子具有作为健康宏量营养素和生物活性化合物来源的潜在价值。

期刊介绍： The Journal of the American Oil Chemists’ Society (JAOCS) is an international peer-reviewed journal that publishes significant original scientific research and technological advances on fats, oils, oilseed proteins, and related materials through original research articles, invited reviews, short communications, and letters to the editor. We seek to publish reports that will significantly advance scientific understanding through hypothesis driven research, innovations, and important new information pertaining to analysis, properties, processing, products, and applications of these food and industrial resources. Breakthroughs in food science and technology, biotechnology (including genomics, biomechanisms, biocatalysis and bioprocessing), and industrial products and applications are particularly appropriate. JAOCS also considers reports on the lipid composition of new, unique, and traditional sources of lipids that definitively address a research hypothesis and advances scientific understanding. However, the genus and species of the source must be verified by appropriate means of classification. In addition, the GPS location of the harvested materials and seed or vegetative samples should be deposited in an accredited germplasm repository. Compositional data suitable for Original Research Articles must embody replicated estimate of tissue constituents, such as oil, protein, carbohydrate, fatty acid, phospholipid, tocopherol, sterol, and carotenoid compositions. Other components unique to the specific plant or animal source may be reported. Furthermore, lipid composition papers should incorporate elements of yeartoyear, environmental, and/ or cultivar variations through use of appropriate statistical analyses.
