摘要
研究不同大孔吸附树脂对蜂王浆中10-羟基-2-癸烯酸的吸附性能,对吸附性能优良的树脂进行解吸性能比较,并对解吸剂进行筛选。结果表明:X-5树脂对10-羟基-2-癸烯酸的吸附及解吸性能最好,其饱和吸附量为9.7mg/g,最佳解吸剂为体积分数90%的乙醇溶液,以90%乙醇溶液进行动态解吸,解吸率达91.7%。真空冷冻干燥获得白色粉末状10-羟基-2-癸烯酸,经高效液相色谱法检测其纯度为80.4%。
10-Hydroxy-2-decenoic acid （HDA）, a special bioactive component in royal jelly, has many physiological functions. In this study, we investigated the adsorption and desorption properties of HDA from royal jelly on macroporous resin and explored the optimal elution solution. X-5 resin had the best adsorption and desorption capacity for HDA and its saturated absorption capacity was 9.7 mg/g. The optimal elution solution was 90% alcohol, resulting in a dynamic desorption rate of 91.7%. The final product prepared by vacuum freeze-drying was white power with a purity of 80.4% as analyzed by HPLC.
