Despite the interest of legumes for food and feed purposes, the phytochemicals of Astragalus armatus (AA), A. caprinus (AC), and A. gombiformis (AG) have not been reported in-depth yet. Thus, the lipid contents, fatty acids composition, proteins, and bioactive compounds in the seeds of these species were investigated. Total lipids were ranged from 12.2 (AG) to 36.5 g 100 g DW (AC) and consisted of oleic acid, linoleic acid, α-linolenic acid, and palmitic acid. The crude protein contents were in the range from 52.2 (AG) to 54.7 g 100 g DW (AA). Globulin and albumin were the predominant soluble protein fractions. The seeds consisted significantly of different contents of total polyphenols (3.4-6.5 mg GAEg DW), total flavonoids (1.24-5.15 mg QEg DW), and total condensed tannins (12-23.2 mg CEg DW). The extracts mainly consisted of quinic acid, p-coumaric acid, and cirsiliol. All these findings can be assets for functional foods and/or food ingredients.
尽管豆科植物在食品和饲料方面具有重要的应用价值，但关于紫云英（Astragalus armatus，AA）、草木樨状黄芪（A. caprinus，AC）和菱叶黄华（A. gombiformis，AG）的植物化学物质尚未进行深入研究。因此，本研究对这三种植物种子的脂质含量、脂肪酸组成、蛋白质和生物活性化合物进行了分析。总脂质含量范围为 12.2（AG）至 36.5 g 100 g DW（AC），主要由油酸、亚油酸、α-亚麻酸和棕榈酸组成。粗蛋白含量范围为 52.2（AG）至 54.7 g 100 g DW（AA）。球蛋白和白蛋白是主要的可溶性蛋白组分。种子中总多酚（3.4-6.5 mg GAEg DW）、总类黄酮（1.24-5.15 mg QEg DW）和总缩合单宁（12-23.2 mg CEg DW）的含量差异显著。提取物主要含有奎宁酸、对香豆酸和梓醇。所有这些发现都可为功能性食品和/或食品成分提供依据。
