摘要
以二氢查耳酮的含量为指标,研究了多穗柯(LithocarpuspolystachyusRehd)叶中二氢查耳酮的纯化方法。结果表明二氢查耳酮纯化的适宜条件为:以聚合氯化铝为絮凝剂,在pH7.5,温度为55℃时絮凝40min;以ADS-7树脂为吸附剂,以100mg/mL为上样液浓度,80%为乙醇为洗脱液浓度。用高效液相色谱法检测,二氢查耳酮的含量达99.02%。
Using Dihydrocharcone content as the key parameter, the purification of Dihydrocharcone was optimized. The results indicated that the best flocculate reagent and sorbent reagent were Polyaluminum Chloride and ADS-7macroporous resin, respectively. HPLC analysis showed that the purity of the dihydrocharcone was 99.02%.
