摘要:

应用AB-8大孔树脂对芦蒿秸秆总黄酮进行富集和纯化,优化得到树脂富集纯化芦蒿秸秆总黄酮的最佳工艺条件;通过显色反应、紫外特征光谱吸收对纯化后的产物进行初步鉴定。结果表明:AB-8大孔树脂具有较好的吸附和解吸性能,最佳吸附洗脱条件为:pH4.0,上样质量浓度1.476mg/mL,上样流速1mL/min,上样体积为树脂体积的2.5倍,洗脱剂为体积分数60%的乙醇,洗脱流速1mL/min,洗脱体积为1.5~2.0BV左右。在该条件下,纯化产品中总黄酮的纯度由5.80%增加到30.26%;显色反应及紫外特征吸收峰显示,芦蒿秸秆总黄酮中可能含有黄酮醇、异黄酮、黄烷酮和双氢黄酮类,并且结构中有邻位双OH存在。

Abstract:

This study aimed at establishing the optimum conditions for purifying total flavonoids from Artemisia selengensis
Turcz with AB-8 macroporous resin. In addition, we preliminarily identified the resulting purified product by means of
chromogenic reaction and UV adsorption spectroscopy. AB-8 possessed excellent adsorption and desorption efficiencies for
total flavonoids. The optimum adsorption and desorption conditions were determined as follows: 2.26 BV of 1.476 mg/mL
sample solution at pH 4.0 was flowed through AB-8 column at a rate of 1 mL/min and then desorbed with 1.5—2.0 BV of
60% ethanol at a flow rate of 1 mL/min. The purity of the purified product obtained under these conditions was 30.26%,
compared to 5.80% for the crude total flavonoids extract. Chromogenic reaction and UV characteristic adsorption indicated
that total flavonoids from Artemisia selengensis Turcz might contain flavonols, isoflavones, flavonone and double hydrogen
flavonols with ortho-dihydroxyl groups in their structure.

Key words: Artemisia selengensis Turcz, total flavonoids, AB-8 macroporous resin, purification, preliminary identification
