To investigate the residue of mycotoxins in Fukang tablets.
The multi-in-one immunoaffinity columns were used to establish a UPLC-MS/MS quantitative analysis method, which was applied to analyze 29 batches of samples collected from six manufacturing enterprises.
The linear relationship of 11 mycotoxins was good within their respective linear ranges, with the correlation coefficient r ranging from 0.996 4 to 0.999 9 and the limit of quantitation (LOQ) ranging from 0.4 to 40 ng/tablet. The average recovery rate of 11 mycotoxins was 74.0% to 115.7%, and the RSD ranged from 2.6% to 11.3%. Among 29 batches of Fukang Tablets, except one batch in which fumonisin B3 (FB3) was measured at 10.4 ng/tablet, while the mycotoxin levels in the other samples were all less than 5 ng/tablet.
This method is rapid, accurate, highly sensitive, and reproducible, making it suitable for the quantitative detection and safety evaluation of multiple mycotoxins in Fukang tablets with complex matrix components.
