The purpose of this work was to study the nutritional and bioactive quality of dried sea buckthorn pomace by proximate analysis and evaluation of total phenolics, total flavonoids, total carotenoids content and ABTS antioxidant activity. In addition, the carotenoid, amino acid and fatty acid profiles were assessed using chromatographic methods while mineral content was determined using graphite furnace atomic absorption spectrometry. Dried sea buckthorn pomace presented high values of the fat (20.05%), crude protein (14.89%) and crude fiber (19.86%) content. The essential amino acids represented 38.42% of total amino acids, the most abundant being leucine, followed by phenylalanine and lysine. The fatty acid profile revealed a high concentration of monounsaturated fatty acids (53.08% of total fatty acids), as a result of the high content of oleic and palmitoleic acids, and a low ratio of n-6/n-3 polyunsaturated fatty acids (1.42). Total carotenoids showed average contents of 245.6 mg/100 g, of which the major ones were β‑carotene (80.76 mg/kg) and zeaxanthin (69.60 mg/kg). The results demonstrated that dried sea buckthorn by-products are valuable sources of nutritional and bioactive compounds and have potential to be used as nutraceutical for feed, as ingredient for functional food, as well as for the pharmaceutical industry.

这项工作的目的是通过对总酚，总类黄酮，总类胡萝卜素含量和ABTS抗氧化活性的分析和评估，来研究干燥沙棘果渣的营养和生物活性质量。此外，使用色谱法评估了类胡萝卜素，氨基酸和脂肪酸的分布，同时使用石墨炉原子吸收光谱法确定了矿物质的含量。沙棘果渣干表现出较高的脂肪含量（20.05％），粗蛋白含量（14.89％）和粗纤维含量（19.86％）。必需氨基酸占总氨基酸的38.42％，最丰富的是亮氨酸，其次是苯丙氨酸和赖氨酸。脂肪酸谱显示高浓度的单不饱和脂肪酸（占总脂肪酸的53.08％），n -6 / n -3多不饱和脂肪酸（1.42）。类胡萝卜素的平均含量为245.6 mg / 100 g，其中主要成分为β-胡萝卜素（80.76 mg / kg）和玉米黄质（69.60 mg / kg）。结果表明，干燥的沙棘副产品是营养和生物活性化合物的重要来源，并且有潜力用作饲料的营养保健品，功能性食品的成分以及制药行业。
