구기자나무 재배(栽培)시 이른봄에 대양(大量) 생산(生産)되는 구기순 및 구기줄기의 용매(溶媒)별 추출물(抽出物)의 물리적(物理的) 특성(特性)을 조사한바 주요 결과는 다음과 같다. 1. 명도(L), 적도(a), 황색도(b), 갈색도 등 색(色)는 물추출물이 에탄을 추출물보다 명도(L)는 낮고, 적도(a), 황색도(b)는 높았다. 2. 탁도 또한 물추출의 침우가 높았으며 추출 수율과는 특이성이 없었다. 3. pH는 모든 처리구에서 약산성을 나타내었다.
The hunter values, pH, turbidity, brownness and solid yields of extracts in a shoot and stem of Lycium chinense were investigated. The results were as follows; The relationships between solid yield and turbidity according to extract solvents was not significant. The range of pH were 5.4 to 6.17 and the acidity of extracts were slitely low. Lightness of water extract was lower than that of ethanol extract, but red and yellowness of water extract was higher than that of ethanol extract. And also turbidity of water extract was higher in water extracts.
