Although noble and precious metal resinates, a reaction product of noble and precious metal chlorides with balsam sulfide yielded by the reaction of balsam with sulfur, has been used for long time to decorate pottery and crafts, their structures have not been clarified yet. In this study, we analyzed the noble and precious metal (Au or Pt) resinates in electrospray ionization-mass spectrometry (ESI-MS) combined with ion mobility spectrometry (IMS). In 2D heat map of m/z and drift time, the compounds containing the precious metals were successfully separated from the organic components without the metal. The MS/MS measurements of the metal-complexes reviled that they were composed of Au/Pt, S, Cl, α-pinene and cymene yielded from α-pinene.
