| 摘 要： | 以冬枣为试验材料,分别用蒸馏水、无水乙醇、丙酮、乙醇-盐酸、0.2 mol/L氢氧化钠和0.2 mol/L碳酸钠溶液为提取剂,从冬枣果皮中提取冬枣红色素.试验结果表明,0.2mol/L氢氧化钠提取效果最佳.同时对提取色素进行酸碱性、光谱以及典型特征性试验进行研究,结果显示,该色素提取物至少含有两种色素化合物,初步判定为黄酮类和花色苷类.此外,对冬枣色素稳定性研究表明,其对热及直射光稳定性较差.

| Abstract: | The extract method of pigments from the dongzao jujube(zizyphus jujube mill.cv.dongzao)with distilled water,absolute ethyl alcohol,acetone,ethyl alcohol-hydrochloric acid,Na 2 CO 3 and NaOH solution was studied.The results indicated that the NaOH solution was the best extraction.At the same time,the deliquescence,acidity,as well as the spectrophotometic characteristics of the ex-tract suggested that the extracted pigments were perhaps constituted of flavone and anthocyanin.The analysis of the stability of the ex-tract pigments under different light and temperature conditions proved that it was sensitive to the direct light and temperature. |
