| Abstract: | OBJECTIVE To study the optimum technology for separating the pigment from the flower of Bauhinia aurea Levl.. METHODS Using orthogonal design experiments and single factor experiments, with the adsorption and desorption capacities as the indexes, to confirm optimal conditions.RESULTS The single factor experiment confirmed X-5 that resin and acetone were the best adsorbent and desorbing agent. The optimum conditions of the orthogonal experiments were as follows: concentration of flower solution was 2 mgml~(-1) , the flow rate of adsorption was 1 mlmin~(-1), the ratio of diameter and height of resins was 23. CONCLUSION The product yield of the pigment is up to (3.8% )and the colouration of the fine pigment is 264.3. |
