본 연구는 뜰보리수의 영양성분 및 생리활성 물질을 조사하여 식품학적 가치를 평가하고자 하는 연구의 일환으로 뜰보리수 잎의 영양성분을 분석하였다. 뜰보리수 잎의 수분, 탄수화물, 조단백, 조지방 및 조회분의 함량은 각각 71.6, 24.1, 1.4, 0.4 그리고 2.5%이었다. 뜰보리수 잎의 환원당과 수용성 단백질의 함량은 각각 460.0, 503.3 mg/100 g이었으며, 항산화성 기능을 가지고 있는 폴리페놀의 함량은 805.6mg/100 g

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.
