Abstract

We analyzed rutin content using mulberry genetic resources. They were grown under the same environment and conditions. Mulberry leaves were collected and then freeze-dried and powdered for rutin test. As a result, mean content of mulberry strains was $0.38{\pm}0.17%$, and the coefficient of variation (CV) was 45.7%. The variation was greatly severe. Among the tested strains, 'Jangloe' was showed the highest content of 0.97%, whereas 'Sungsu 3' was showed the lowest content of 0.01% respectively. Finally we selected rutin high-containing 6 strains. They are as follows. 'Jangloe', 'Pumbo 6', 'Youjin', 'Kaeryangjeonjeon', 'Baekhak', and 'Pumbo 32' which are more than twice of the overall average content.

뽕잎의 기능성 성분이나 효능에 대한 소비자들의 관심이 높아짐에 따라 이에 대한 기초정보를 구축할 필요성이 제기되었다. 따라서 우리나라 620 계통(품종)의 뽕나무 유전자원 중 재배환경 및 재배법이 동일한 119 계통의 춘기 5개엽기 뽕잎을 채취한 후 동결건조 및 분말로 제조하여 뽕나무 유전자원의 계통별 rutin 함량을 분석하였다. 그 결과, 119 계통의 뽕잎 rutin 평균 함량은 $0.38{\pm}0.17%$이었으며, 변이계수(CV)는 45.7%로 계통간 변이가 매우 심하게 나타났다. 공시계통 중 '장뢰'의 rutin 함량이 0.97%로 가장 높았으며, '성수3'은 0.01%로 가장 낮았다. 뽕나무 유전자원 중 '품보6', '유진', '개량전전'은 각각 0.95%, 0.83%, 0.80%로서 전체 평균 함량의 2배 이상 되는 함량을 나타냈으며, '백학'과 '품보32' 계통은 각각 0.75%, 0.70%로 누에사육용 뽕 품종 중 가장 높은 함량을 나타낸 '청올뽕'(0.69%)보다 높았다. 따라서 이들 6계통은 뽕 육종이나 식의약용 소재로 개발코자 할 경우 우선 고려할 만한 대상들로 판단되며, 자연발효 등의 기법에 의해 rutin 함량을 증대시킨다면 더욱 그 이용이 기대되는 계통으로 여겨진다.
