적 요쪽 종자의 이용성 향상을 위한 기초 자료 확보 측면에서 쪽종자의 일반성분, 지방산, 무기물, 아미노산 함량 분석과 쪽 종자의 메탄올 추출물을 이용하여 생리활성 효과를 조사하였다. 쪽 종자의 총 열량은 348.00 kcal/100 g이었으며, 일반성분은수분 7.85%, 탄수화물 67.90%, 조단백 10.10%, 조지방 4.00%, 조회분 10.15%로 구성되어 있었다. 포화지방산의 총량은 0.905 g/ 100 g이었고, 불포화지방산의 총량은 2.717 g/100 g이었다. 쪽종자 100 g에 함유된 무기질은 K (549.5 ㎎), Mg (264.4 ㎎), Ca(216.2 ㎎), Fe (12.1 ㎎), Zn (3.0 ㎎) 순으로 많았다. 구성아미노산은 총 15종이 검출되었으며, 이 중 alanine (1,432.6 ㎎/ 100 g)과 glutamic acid (1,088.8 ㎎/100 g)의 함량이 많았다. 총 폴리페놀 함량은 11.08 ㎎/L였고, 총 플라보노이드 함량은3.56 ㎎/L였다. 쪽 종자 메탄올 추출물의 생리활성 중 radical scavenging activity는 1,000 ㎎/L일 때 DPPH radical 소거능86.74%, ABTS radical 소거능 61.74%로 나타났다
Abstract
In order to improved use of Persicaria tinctoria seeds and to get basic information, general composition, fatty acid, mineral, amind acid analysis and physiological activity of methanol extract of Persicaria tinctoria seeds were investigated. Total calories of Persicaria tinctoria seeds were 348.00 kcal/100 g, general composition, carbohydrate, crude protein, crude fat and crude ash consisted of 7.85%, 67.90%, 10.10%, 4.00% and 10.15%, respectively. The amount of saturated and unsaturated fatty acids was showed 0.9048 g/100 g and 2,714 g/100 g, respectively. Minerals contained 100g of Persicaria tinctoria seeds were followed by K (549.5 ㎎), Mg (264.4 ㎎), Ca (216.2 ㎎), Fe (12.1 ㎎), Zn (3.0 ㎎). Total 15 kinds of amino acids were detected, these amino acids displayed higher value in the alanine (1,432.6 ㎎/100 g) and glutamic acid (1,088.8 ㎎/100 g). Total polyphenol and flavonoid contents were 11.08 ㎎/L and 3.56 ㎎/L, respectively. DPPH radical scavenging and ABTS radical scavenging activity in the methanol extract of 1,000 ㎎/L was showed 86.74% and 61.74%, respectively. Key words - ABTS radical scavenging, DPPH radical scavenging, Flavonoid, Indigo plant, General composition
