뽕나무 어린줄기를 이용하여 새로운 기능성 추출 음료개발을 위한 목적으로 뽕나무 줄기의 화학성분, 항산화 및 항균활성을 조사하였다. 일반성분은 조섬유 51.12%, 회분 13.46%, 총당 10.38%, 조지방 9.10% 및 조단백 5.01% 순으로 나타났다 뽕나무 어린줄기에 가장 많은 무기성분으로는 P(295.9 mg%)으로 나타났으며, 그 외 Ca 289.6 mg%, K 209.6 mg%, Na 58.3 mg%, Mg 45.0 mg% and F
In order to exploit as a new functional decocted beverage, chemical components, antioxidative and antimicrobial activities young stems of mulberry(Morus alba) were surveyed. The proximate composition was composed of crude fiber 51.12%, ash 13.46%, total sugar 10.38%, crude fat 9.10% and crude protein 5.01%. The P(295.9 mg%) was the highest mineral found in young stem of mulberry and Ca 289.6 mg%, K 209.6 mg%, Na 58.3 mg%, Mg 45.0 mg% and Fe 4.6 mg% in that order. Free sugars was composed of glucose 1.08%, galactose 022%, sucrose 0.20% and fructose 0.16%. Eight fatty acids in stem of mulberry were identified and the major fatty acids were linoleic acid(46.10%), palmitic acid(27.84%) and linolenic acid(10.85%). Among the 17 amino acids detected, total amino acid was 2,450.5 mg% and proline(313.7 mg%) was the most predominant. Methanol extract and ethyl acetate fraction showed stronger activity of the hydrogen donating activities, each of 77.24% and 80.08%, respectively. The methanol extract from young stem of mulberry showed the strongest antimicrobial activities to Bacillus subtitis and Bacitus cereus. Chloroform and ethyl acetate fractions from methanol extract of young stem showed a inhibition zone of 9.0∼19.0 ㎜ in diameter against pathogen bacteria.
