Method for simultaneously detecting sibutramine and fenfluramine in weight-losing health-care products

The invention relates to the technical field of detection, and discloses a method for simultaneously detecting sibutramine and fenfluramine in weight-losing health care products. The preparation method comprises the following steps: (1) preparing a core-shell substrate solution, performing centrifugation, adding an obtained centrifugal product into a material bearing device, putting the material bearing device into a drying oven, performing drying at the temperature of 60-70 DEG C, after 1-2 hours, turning over one side of a core-shell material, and continuing drying for 0.5-1 hour to obtain a core-shell substrate material; and (2) mixing the sample liquid to be detected with the core-shell substrate material, then carrying out surface enhanced Raman spectrum detection, and collecting corresponding spectral information. The raw material drying efficiency can be improved, and the required drying time is shortened. 本申请涉及检测的技术领域，公开了一种同时检测减肥类保健品中西布曲明和芬氟拉明的方法，包括以下步骤；（1）制备核壳基底溶液并进行离心，并将得到的离心产物加入到承料装置中并放入烘箱中于60-70℃的
