Abstract
This study analyzed components of the leaves of Elaeagnus multiflora as part of studies on the nutritional and functional materials of fruits and leaves of this plant. The moisture content of the leaves was 71.6% and the carbohydrate, crude protein, lipid and ash contents were 24.1, 1.4, 0.4 and 2.5%, respectively. Concentrations of reducing sugars, soluble proteins and polyphenols were 460.0, 503.3 and 805.6 mg/100 g, respectively. Fructose was the dominant free sugar, and arabinose, maltose, glucose, and a small amount of trehalose were also detected. Malic acid was the main organic acid in E. multiflora leaves, and acetic acid, citric acid, lactic acid, and succinic acid were also present. E. multiflora leaves were high in K, Ca and Mg. Of hydrolyzed amino acids, alanine was present at the highest concentration (112.0 mg/100 g), with threonine, leucine, valine and phenylalanine being the next most common. Glutamic acid and ornithine were the dominant free amino acid and amino acid derivative, respectively.
