Convenient Methods for the Extraction and Discrimination of Water-Soluble Plant Pigments

Abstract

The use of colorants as additives for foods and drinks is a significant factor to food consumers in determining the acceptability of processed foods. In recent years, the number of previously used artificial colorants/dyes suitable for food use has been drastically reduced as a result of toxicological studies. Therefore, the use of natural pigments such as anthocyanins and betacyanins that were known to have anticancer and antioxidant activities is increasingly required. In this study, the water-soluble plant pigments, anthocyanins and betacyanins, were easily extracted with a very simple method using a few organic solvents such as ethyl acetate, ethyl ether, and chloroform. After the extraction of them, these two major plant pigments could be also simply and rapidly separated and discriminated by a solely one-stepped agarose gel electrophoresis in a citrate buffer (pH 3.0). ■ keyword :|Pigment Extraction|Discrimination between Anthocyansins and Betacyanins|Gel Electrophoresis|

“…1). 주요물질인 베타닌 은 항암효과뿐만 아니라 항산화 작용이 높다 (Chung and Byun, 2009). 또한 베타닌 색소를 함유한 비트 묘목은 비색 소 묘목보다 식물 병원균 Phythium debaryum에 저항성이 큰 항균성 작용을 하며 비독성 물질로 화장품, 제약, 식품 산 업에 천연색소 첨가물로 이용된다 (Gabrela et al, 2004).…”
