Abstract

This study was conducted to investigate the possible use of Mulberry leaf as a functional supplement for Mulberry leaves. Chemical characteristics of mulberry leaf were investigated in eleven mulberry varieties, including Suwon, Chongil, Gumseol, Sugae, Yongchun, Hongol, Daeryk, Kaerang, Donae, Chungol and Kuksang20 varieties. The chemical compositions of minerals, amino acids, rutin as flavonol glucoside were analyzed by AOAC methods, HPLC method, amino acid analyzer, respectively. The results are as follows: In case of KukSang Mulberry leaf with spring harvest, the content of general components was crude protein 16.28%, carbohydrate 69.12%, crude fiber 9.15%, crude ash 8.44% and crude fat 2.57% respectively. It is noteworthy that ferrious content of KukSang mulberry leaves contains twice as great as that in other variety of mulberry leaves. The content of alanine was the highest among amino acids in all variety mulberry leaf. Spring leaf contain more utin content than fall leaf, among the variety, spring HongAll leaf rutin contain 260mg/100g as higher than that of fall ChungAll leaf 70mg/100g).
