Randomized trial evaluates pesticide residues in traditional Chinese medicines, indicating a need for safety standards.
> 0.999) from 1-50 ng/g. The method detection limits (MDLs) and quantification limits (MQLs) were 0.003-0.004 mg/kg and 0.01 mg/kg, respectively. Average recoveries ranged from 60% to 121% with RSDs ≤ 20.0%. Application to 120 commercial batches revealed 98 pesticides, with farmland-grown root/rhizome TCMs showing the highest levels (e.g. diphenylamine at 317 μg/kg). The validated method establishes a robust high-throughput platform for global regulatory monitoring. By addressing the extreme chemical diversity of food-medicine plants, this study provides a standardised solution for ensuring the safety and international trade compliance of TCMs in the global functional food market.
