Abstract:

Bodybuilding products are also known as slimming products or anti-cellulite products, produced body shaping and bodybuilding. Through massage and hot compresses, the active substances of cosmetics are absorbed into the body, which help to decompose subcutaneous lipolysis, accelerate subcutaneous fat metabolism, and reduce edema. Due to the special way of use, large use area, and long stay time, the potential safety risks have been paid more and more attention by the consumers. There is a high risk that it may add prohibited substances. Currently, there is little literature on the determination of slimming drugs in bodybuilding products. Therefore, it is necessary to establish a method for the determination of components in these products. In this paper, an effective method of high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was established for the determination of 33 kinds of components such as caffeine in bodybuilding products. The samples were extracted using methanol, and filtered through a 0.22 μm filtering membrane after centrifugation with high speed. The analysis was performed on an AtlantisdC18(2.1 mm×100 mm×3 μm)at 30 ℃ with 0.1% formic acid-acetonitrile as the mobile phase by gradient elution at the flow rate of 0.3 mL/min. The matrix curve was quantified by external standard method. The results show that the method has good linearity with correlation coefficients exceeding 0.99. The recoveries at different concentrations are between 80.7%-118.2%, and the relative standard deviations (RSDs) are less than 10%. The limit of detections (LODs) are 0.003-0.015 μg/g. The method proves to be simple, rapid, suitable for the determination of caffeine and others in bodybuilding products.
