Citation abstract

OBJECTIVE: To establish a method for simultaneous analysis of 22 inorganic elements in Antrodia camphorata powder by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Additionally, inorganic elements of Ganoderma lucidum had been detected and compared.

METHODS: The sample solutions were analyzed by ICP-MS after microwave digestion and the contents of elements were calculated according to their calibration curves. The data of correlations and principal components were analyzed with the SPSS 17.0 software.

RESULTS: 22 inorganic elements were determined in Antrodia camphorata powder. And there are some correlations among the inorganic elements in Antrodia camphorata powder. In addition to the element K, the content of Ca and Mg was also abundant. The content of heavy metals and harmful elements should be pay more attention.

CONCLUSION: The study indicates that ICP-MS is a quick, accurate and sensitive method for determining the content of inorganic elements in Antrodia camphorata powder, which provides a scientific reference for the quality analysis and safety assessment of Antrodia camphorata powder.
