Abstract:In this study，the fruit of Amelanchier sinica （C. K. Schneid.） Chun was taken as the research subject to explore the content of routine nutritional composition，amino acids，and bioactive components. According to the results，moisture，ash，and fat content in the fruit were 77.66%，2.66%，and 0.94%，respectively. Protein content was 0.57 mg/g，and reducing sugar content was 94.80 mg/g. The content of 18 amino acids was 21.15 mg/g，and the content of non-essential amino acids was 15.00 mg/g. Vitamin C content was 0.21 mg/g.VB1，VB3，and VB6 content were 0.02，0.03，0.04 mg/g，respectively. The total flavonoid，total polyphenol，polysaccharide，and anthocyanin content were 11.77，5.21，198.60，0.71 mg/g，respectively. In conclusion，the fruit of A. sinica was rich in nutrients and had active ingredients such as flavonoids，polyphenols，and anthocyanins.Therefore，with high development and utilization value.
