Seabuckthorn is a unique berry plant belonging to the Hippophae genus in the Elaeagnaceae family. Known for its remarkable resilience, it is widely planted across China for windbreak, sand-fixing, and soil improvement due to its nitrogen-fixing root system. The nutrient profile of seabuckthorn fruit is exceptionally rich, containing multiple vitamins, fatty acids, microelements, and essential amino acids. Notably, its Vitamin C content is among the highest globally, ranging from 825-1100mg/100g. The flavonoids extracted from the pulp primarily consist of isorhamnetin, quercetin, and kaempferol.
