Highly nutritious traditional plants which are rich in bioactive substances are attracting increasing attention. In this study, the nutritional value, chemical composition, biological activities, and feed indices of different parts of were comprehensively evaluated. In terms of its nutritional value, this study demonstrated that the leaves, flowers and seeds of were rich in elements and amino acids; the biological values (BVs) of these ingredients ranged from 85% to 100%, showing the extremely high nutritional value of this plant. GC-MS analysis suggested that the main chemical components of the flower volatile oil were -hexadecanoic acid (21.73%), tetracosane (19.96%), and pentacosane (5.86%). The antibacterial activities of the flower and seed extracts were significantly stronger than those of the leaves and branches. The leaf extract displayed the strongest antifungal activities (EC values: 18.28 ± 0.54 μg/mL for and 568.21 ± 33.60 μg/mL for ) and were the least toxic to mouse fibroblasts (L929) (IC value: 0.71 ± 0.04 mg/mL), while flowers were the most toxic (IC value: 0.27 ± 0.03 mg/mL). In addition, the abundance of fiber, protein, mineral elements, and functional metabolite contents indicated the potential applicability of as an animal feed. In conclusion, as a traditional herbal plant used for medicinal and food purposes, shows potential for safe and multifunctional development.
