This study was conducted to analyze components of the fruit of Etaeagnus multiflora to form a part of studies on the nutritional and functional materials of fruits and leaves of E. multiflora, and the development of a functional food. The moisture content of the fruit was 82.34%, and the content of carbohydrate, crude protein, lipid and ash was 15.4, 1.29, 0.79 and 0.54%, respectively. The pH of the fruit extract was 3.29, acidity 0.64%, and brix 14.0. Total sugar was contained 1.03/100g and reducing sugar was 3.27 g/100g. The content of soluble protein was 0.48 g/100g, and polyphenol was 0.28 g/100g. The glucose and fructose as a free sugar was 401.96 and 370.34 mg/100g, and account for a great portion of the components. Total content of free sugary was 0 mg/100g. The total amount of organic acid was 294.44 mg/100g, and the content of citric acid was 265.01 mg/100g, malic acid 18.16 mg/100g, and succinic acid 8.50 mg/100g. In the free amino acid, the concentration of serine was the highest (13.93mg/100g), and alanine, aspartic acid, cystine and methionine were high in the above order. The content of ascorbic acid was 131.35 mg/100g and that of dehydroascorbic acid was 431.37 mg/100g. Potassium, magnesium and sodium content were 627.44, 140.28, and 56.70 mg/100g, respectively.
