Abstract:Sea buckthorn is a medicinal and food homologous plant, and its fruit is rich in active ingredients, mainly including vitamins, flavonoids, phenolic acids, polysaccharides, fatty acids, minerals and proteins. Studies have shown that sea buckthorn plays an important role in antioxidant, anti-aging, anti-tumor, hypoglycemic, immunomodulatory, intestinal flora-improving, cardiovascular diseases-alleviating, anti-inflammatory and muscle-building processes, and has a very broad application prospect in food, skin care products and pharmaceutical industries. In recent years, sea buckthorn has become the focus of research by scholars at home and abroad. However, there is a lack of systematic research on the active components and physiological functions of sea buckthorn. In this paper, the active ingredients, functional properties and application status of sea buckthorn reported in the domestic and foreign literature were systematically reviewed, aiming to provide a theoretical basis for the comprehensive development and utilization of sea buckthorn.
