The aim of the experiment was to study the optimum conditions for distilling and purifying red pigment from mulberry through AB-8 macroporous resin.Taking adsorption quantity and desorption rate as indexIt researched the influence of several kinds of fectors to red pigment for lixiviating and eluting from AB-8 macroporous resin.The result showed that the optimum lixiviation conditions were as follows: lixiviating time at 2h,concentration of alcohol at 75%,material ratio at 1∶3,temperature at 60℃;the optimum...
