密蒙花黄色素性质研究 Studies on the Properties of Yellow Pigment from Buddleja officinalis Maxim

食品研究与开发２０14 年 2 月基础研究Ｆood Research And Development 第 35 卷第 4 期 19 DOI ：10.3969/j.issn.1005-6521.2014.04.005 密蒙花黄色素性质研究杨胜远，李卓文，赖演莲，方晓旋，陈晓屏，杨娜（韩山师范学院生物学系，广东潮州521041 ）摘要：对密蒙花黄色素的性质进行了研究。结果表明，密蒙花黄色素易溶于水，难溶于石油醚，在不同溶剂中的溶解性为水＞无水乙醇＞丙酮＞石油醚。密蒙花黄色素在 4 、30 ℃、pH4.92～9.18 范围内稳定，但高温、光和 EDTA 对其色价有一定影响。密蒙花黄色素具有较强 DPPH 自由基清除能力，每毫克密蒙花黄色素与 10.01 μg Trolox 自由基清除能力相当。在 10 g/L 的浓度下，密蒙花黄色素对大肠杆菌、金黄色葡萄球菌、枯草芽胞杆菌、副溶血性弧菌、酿酒酵母、匍枝根霉、黑曲霉和桔青霉均没有抗菌活性。关键词：密蒙花；黄色素；性质 Studies on the Properties of Yellow Pigment from Buddleja officinalis Maxim YANG Sheng-yuan ， LI Zhuo-wen ， LAI Yan-lian ， FANG Xiao-xuan ， CHEN Xiao-ping ， YANG Na （Department of Biology ， Hanshan Normal University ， Chaozhou 521041 ， Guangdong ， China ）Ａｂｓｔｒａｃｔ： The properties of yellow pigment from Buddleja officinalis Maxim were investigated. The results indicated the yellow pigment from B. officinalis Maxim was easily dissolved in water and poorly soluble in petroleum ether ， and the solubility of the yellow pigment in different solvents was water absolute ethyl alcohol acetone petroleum ether. The yellow pigment was stable at 4 ， 30 ℃ and pH 4.92-9.18 ， but its stability was effect by high temperature ， light and EDTA. The yellow pigment shows strong DPPH radical scavenging activity which was equal to 10.01 μg Trolox/mg ，and shows no antimicrobial activities to Escherichia coli ，Staphyloccocus aureus ， Bacillus subtilis ， Vibrio Parahemolyticus ， Saccharomyces cerevisiae ， Rhizopus stolonifer ，Aspergillus niger and Penicillium citrinum at 10 g/L.
