| 摘 要： | 以麦麸酶法降解液为原料,采用D201大孔树脂对阿魏酸进行分离提纯,探讨了上柱工艺条件和洗脱条件,确定最佳离子交换操作工艺:室温下,料液阿魏酸浓度在2000mg/L～3000mg/L之间,pH值9.0,上柱流速1 ml/min,洗脱剂配比(V/V)为无水乙醇: 水: 盐酸＝60: 36: 4,洗脱流速为1 ml/min.在该操作工艺条件下,阿魏酸收率达97%以上,且纯度大大提高.

| Abstract: | Anion-exchange resin, D201 was used to prepare ferulic acid from the enzymatic hydrolysate of wheat-bran and the influence of adsorption and desorption operation was researched. The optimal technology is as follows: under the room-temperature, the concentration of ferulic acid in the extraction solution is 2000 mg/L to approximately 3000 mg/L, pH and flow velocity were kept around 9.0 and 1 ml/min respectively; elution solution is composed of ethanol: water: HCl in ratio 60:36:4 (v/v), and the velocity of elution is 1 ml/min. Under optimal conditions,the recovery percent of ferulic acid from enzymatic hydrolysate exceed 97% and the purification production is in evidence. |
