Abstract

Extracting natural dyes have been widely studied since the needs of eco-friendly and non-toxic natural dyes increased. In this paper, the natural dyes were extracted from sappan wood, gardenia, and mugwort containing brazilein, crocin, and chlorophyll process. After the extraction with variables of pH of solvent and reaction time, the chromaticity of extracted natural dyes was analyzed using quantitative values from brightness and color coordinate (L, a, b) based on the target colors of red, yellow and green. For the case of brazilein and crocin, the cadmium red and cadmium yellow, respectively were extracted. In the case of sappan wood and gardenia, the red pigment under pH 12 (${\Delta}$ = 18.2) and the yellow pigment at pH 9 (${\Delta}$ = 18.4) were extracted respectively. However, the color of extracted chlorophyll from mugwort was different from the target chrome green.

환경 친화적이고 질병을 유발시키지 않은 천연색소의 사용이 증가함에 따라 천연색소를 추출하는 다양한 방법이 연구되고 있다. 본 연구에서는 천연염료인 brazilein, crocin, chlorophyll을 포함하고 있는 식물성 원료인 소목, 치자, 쑥을 대상으로 천연염료를 추출하였다. 추출용매의 pH와 추출시간을 변수로 추출된 천연염료의 적색, 황색, 녹색계열의 목표색을 설정하고 추출된 천연염료의 명도와 색의 좌표(L, a, b)의 정량적 수치로부터 색도분석을 수행하였다. 소목의 적색소인 brazilein과 치자의 황색소인 crocin의 경우 목표색인 카드뮴 레드와 카드뮴 옐로에 근접한 색상을 추출할 수 있었다. 추출시간 20 min을 기준으로 brazilein의 경우 pH 12, crocin의 경우 pH 9에서 색차를 나타내는 ${\Delta}E^*$가 각각 18.2와 18.4로 목표색과 유사한 색의 색소가 추출되었다. 그러나 쑥의 녹색색소인 chlorophyll의 경우 목표색인 크롬 그린과는 차이를 보였다.
