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.

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 g이었다. 뜰보리수에 함유된 유리당은 fructose가 가장 많았으며, 그 외 arabinose, maltose, glucose 순이었으며, trehalose는 미량 검출되었다. 뜰보리수 잎은 malic acid가 주요 유기산이었으며, 이외 acetic acid, citric acid, lactic acid, succinic acid순으로 높았다. 뜰보리수 잎의 무기질 성분중 K의 함량이 840.5 mg/100 g으로 가장 높았고, Ca과 Ma도 많은 양 함유되어 있었다. 뜰보리수 잎의 구성아미노산 중 alanine의 함량이 112.0 mg/100 g으로 가장 높았으며, threonine, leucine, valine, phenylalanine 순으로 높았다. 그리고 유리아미노산은 glutamic acid가 57.3 mg/100 g으로 가장 많이 함유되어 있었으며, 그 다음으로는 arginine, leucine, glycine, phenylalanine 순이었다. 아미노산의 유도체는 11종이 검출되었으며, ornithine의 함량이 48.5 mg/100 g으로 가장 높게 분석되었다.
