Objective: To Study Chrysanthemi Flos variety of elements content in the samples before and after sulphur fumigated differences

and try to establish sulphur fumigated Chrysanthemi Flos qualitative identification method. Method: Using Ultrwave Digestion/ICP-MS testing before and after sulphur fumigated Chrysanthemi Flos

a variety of mental elements content in combined with principal component analysis (PCA) scatter distribution method to distinguish between sulphur fumigated and non sulphur fumigated Chrysanthemi Flos. Result: Nine batches of stoving of sulphur fumigated Chrysanthemi Flos samples and nine samples of each element content comparison found that Ba and Cu element content increased after sulphur fumigated Chrysanthemi Flos medicine materials and has significant; Pb and As element content increased slightly

but not significant; Hg element content has no obvious change; Cd element content in the sulphur fumigated Chrysanthemi Flos samples slightly lower but not significant; 9 batches of sulphur fumigated Chrysanthemi Flos and 9 batches non-sulphur fumigated Chrysanthemi Flos distribution distance is relatively loose

able to complete stoved Chrysanthemi Flos and non-sulphur fumigated Chrysanthemi Flos to distinguish the identification. Conclusion: Methodology to investigate the results show that this method conform to the requirements of the measurement

the method can be applied to quality control of sulphur fumigated Chrysanthemi Flos and safety inspection

to explore stoved Chrysanthemi Flos and other sulphur fumigated the distinction between tradition Chinese medicine identification provides important data.
