Abstract

[Objectives] This study aimed to analyze the dyeing status and dyeing components of counterfeit cinnabar (elutriation), in order to provide technical basis for cinnabar (elutriation) supervision. [Methods] The scarlet 808 in cinnabar (elutriation) was identified qualitatively using thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC), and the positive samples were confirmed by high-performance liquid chromatography-mass spectrometry (HPLC-MS). The conditions were as follows: column, Agilent Eclipse Plus C18; mobile phase, acetonitrile-0.1% formic acid (85:15); detection wavelength, 520 nm; ion source, electrospray ion source; scanning mode, positive ion scanning; scanning range, 100-700 m/z; cone voltage, 3.5 kv; drying gas temperature, 350℃; drying gas flow rate,12 L/min. [Results] The thin-layer chromatography spots were clear and separated well. Among the 13 batches of samples, 12 batches were positive for scarlet 808. [Conclusions] The counterfeit cinnabar (elutriation) currently circulating in the market has dyeing problem, with scarlet 808 as the dye. The TLC, HPLC and HPLC-MS methods established in this article can quickly screen and confirm the scarlet 808 in cinnabar (elutriation).
