A new solid-phase extraction mode was developed for separation some flavones from the complex interference system. In the experiment, rhein anchored on magnetic chitosan microparticles, prepared facilely without removal of the template molecule, was used as sorbents for the extraction of target analytes; after completion of the extraction process, FeO particles acted as carrier to retrieve rhein functionalized magnetic chitosan microparticles (RMCMPs) from the sample solution. RMCMPs showed excellent selective adsorption capacity of isoflavones. The result suggested that the method was useful for fast determination and quantification of isoflavones in soymilk. The RMCMPs were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and Fourier transforms infrared spectrometer (FTIR).
一种新的固相萃取模式被开发出来，用于从复杂的干扰体系中分离一些黄酮类化合物。在实验中，大黄素锚定在磁性壳聚糖微球上，无需去除模板分子即可简便地制备，用作目标分析物的萃取剂；萃取过程完成后，FeO 颗粒作为载体，从样品溶液中回收大黄素功能化磁性壳聚糖微球（RMCMPs）。RMCMPs 对异黄酮具有优异的选择性吸附能力。结果表明，该方法可用于快速测定和定量豆浆中的异黄酮。RMCMPs 通过扫描电子显微镜（SEM）、X 射线衍射（XRD）和傅里叶变换红外光谱仪（FTIR）进行了表征。
