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-1 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-1 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-1 DW), total flavonoids (1.24-5.15 mg QEg-1 DW), and total condensed tannins (12-23.2 mg CEg-1 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.
