Nutritional and Phytochemical Composition and Antioxidant Activity of Edible Stems of Smooth Cordgrass ().

Smooth cordgrass () is a native salt marsh plant along the Atlantic coast but has become an invasive species in coastal regions in China, as well as other areas. Utilizing it for resources has become a control measure in reducing the spread of . This study assesses the nutritional and phytochemical properties of the edible stems of collected from three locations in Fujian province, China. The tender stems of exhibit a rich nutritional profile, with high levels of protein, carbohydrates, and fats, and significant amounts of essential vitamins, minerals, and antioxidants, indicating their potential as a nutritious addition to the diet or forage. In addition, the levels of potential contaminants, including nitrate, nitrite, cadmium, lead, and chromium, are below the established safe thresholds for consumption. Our results provide valuable information for the sustainable utilization of resources and will contribute to the integrated control of
