摘要
研究了DM-130型大孔吸附树脂对绞股蓝黄酮类化合物的吸附性能。结果表明最佳富集精制条件为:浸出液的pH值为4.00,浸出液与树脂的液固质量比为15∶1,过柱流速为0.5 mL/m in,洗脱剂为70%的乙醇水溶液,洗脱剂与树脂的液固质量比为7∶1,黄酮得率为3.75%,提取率可达89.8%。
DM-130 type resin was confirmed to have optimum adsorption properties for flavones from Gynostemma pentephyllum. The experimental results showed that the optimum refine technial conditions are as following： extract solution pH =4.00, current velocity of 0.5 mL/min, ratio of extract solution （mL） to macroeticular adsorbent （g） is Is. , eluant is 70% alcohol and its volume（mL） is 7 times of macroreticular adsorbent（g）. The flavone product was obtained in 3.75% yield with 89.8% extraction rate.
