AB  - A multiclass analysis approach was developed using magnetic multiwalled carbon 
      nanotubes sorbents and ultra-high performance liquid chromatography-quadrupole 
      time-of-flight mass spectrometry (UPLC-QTOF/MS) for the rapid screening and 
      simultaneous determination of 216 contaminants including 15 mycotoxins, 9 
      synthetic colourants, and 192 pesticides in chilli powder. The sample preparation 
      process was optimized. The optimal preparation procedure utilized NaCl and NaAc 
      as the salting-out agents, and Fe(3)O(4)-MWCNTs as the sorbents, resulting in 
      reduced chemical consumption, improved cleaning performance, and facilitated 
      high-throughput analysis. The proposed method was validated, and satisfactory 
      parameters were obtained. Approximately 85.6% of the target analytes exhibited a 
      weak matrix effect, with the matrix effects falling within the range of 
      0.8  approximately  1.2. The method demonstrated acceptable recoveries of the analytes, falling 
      within the range of 62.14% approximately 119.76% at three fortified levels with relative 
      standard deviations (RSDs) of less than 20%. Additionally, the method's limit of 
      quantification (LOQ) ranged from ranged from 0.50 mug.kg(-1) to 49.56 mug.kg(-1). 
      The method was further applied for analysis of 27 chilli powder samples, 
      demonstrating its potential for screening and quantification of multiclass 
      contaminants for spices.
