Abstract:
Objective To establish an LC-MS method for identification of testosterone and methyltestosterone in cosmetic.Methods Testosterone and methyltestosterone in cosmetic were determined by liquid chromatography mass spectrometry system which can incorporate electrospray ionization interface,post-column addition agent of formic acid.Results The condition of determination was investigated and optimized.The structure of testosterone and methyltestosterone were identified by direct comparison of the observed mass spectra or by the characteristic ions in the selected-ion monitoring as well as MS2 mode.A doubtful testosterone positive cosmetic was identified by this method,it was negative.Conclusion This method has a high sensitivity and a good reproducibility.It is proved that the method is especially suitable for detection of testosterone and methyltestosterone in cosmetics.
