研究335大孔树脂用于吸附分离栀子黄废液中京尼平甙的影响因素,结果表明温度、pH变化对其吸附效果影响不大,在室温条件下pH3~7时吸附率变化不大;采用0.5%的NaOH作为洗脱剂,并将得到的京尼平甙粗品经HPD100大孔树脂进一步脱色后,通过薄层点板分析,纯度较高,且产率达到70%以上。
The results showed that temperature and pH had little effect on the adsorption of geniposide, and the adsorption rate did not change much at pH 3 ~ 7 at room temperature. 0.5% NaOH was used as the eluent. The crude product of Geniposid was further decolorized by HPD100 macroporous resin. The purity of the crude product was higher than 70% by TLC analysis.
