Summary: The popularity of plant food supplements has led to increased adulteration and fraud, making it necessary to develop a screening approach for the detection of regulated plants in these supplements. This paper proposes a multidimensional chromatographic fingerprinting method aided by chemometrics to address this problem. The method combines ultra-high-performance liquid chromatography (UHPLC) with diode array detection (DAD) and utilizes partial least squares-discriminant analysis (PLS-DA) for chemometric modelling. The results show that this approach is feasible for identifying regulated plants in complex botanical matrices.

Summary: The dissipation of chlorantraniliprole insecticide in tomatoes treated with Altacor 35 WG was studied in laboratory and greenhouse conditions, and suspect screening analysis was performed to identify transformation products and coformulants. Analyses using UHPLC-Q-Orbitrap-MS and GC-Q-Orbitrap-MS showed that chlorantraniliprole followed a biphasic kinetic model with R2 values greater than 0.99. Dissipation was faster in greenhouse studies, with 96% achieved over 53 days. One transformation product (IN-F6L99) was tentatively identified in both laboratory and greenhouse studies, and 15 volatile coformulants were identified by GC-Q-Orbitrap-MS.

Summary: A stationary reversed phase based on polyhydroxy methacrylate was used to determine coformulants in 20 plant protection products (PPPs) by liquid chromatography coupled to Q-Orbitrap high-resolution mass spectrometry. A total of 92 coformulants were tentatively identified, with 12 of them quantified by analytical standards. The study found that the polyhydroxy methacrylate-based stationary phase increased the identification of new coformulants in PPPs, complementing conventional C18. This strategy could be applied in future studies to estimate potential coformulant residues from PPPs applied to crops.
