摘要
本文对准噶尔山楂色素的提取和精制工艺进行了研究，结果表明：准噶尔山楂色素的最佳提取条件是浸提剂pH3．0的85％乙醇，提取温度25℃，提取时间2h和固液比1：30；用X-5大孔吸附树脂对色素进行精制，以树脂柱径高比1：15、流速3．0mlMmin、pH3．0和色素液浓度1．0g/L为最佳吸附条件，而以95％乙醇做洗脱液，在pH2．0、流速5．0mIMmin和3倍于柱床体积的洗脱条件下解吸附效果最佳；色素色价为28．43。
The extracting and refining technology of pigment from Crataegus songorica K. Koch was studied by orthogonal design in the paper. The best extracting conditions were 85% ethanol using 30 times volume, pH 3.0,25 ℃and 2 h. The X-5 macroporous resin was used to refine the pigment. The best adsorption conditions were 1.0 g/L pigment solution, pH 3.0, velocities of flow 3.0 mL/min, resin diament vs height 1：15 ;The 95 % ethanol as elnting solvent, pH 2.0, velocities of flow 5.0 mIVmin and 3 BV elnting solvent volume were the best desorption conditions. The pigment produced by this method was purple and its colour scale was 28.43.
