Case. Metabolomics-Based Assessment of Botanical Extracts and Pesticide Residue Fate in Fruit Matrices


The study focuses on utilizing untargeted metabolomics, specifically the Exometabolomic Framework (EMF), to investigate the fate of botanical pesticides (BPs) and chemical pesticides in peach peel samples. BPs and chemical pesticides are commonly used in agriculture to protect crops from pests and diseases. Understanding how these compounds degrade and persist in fruit matrices is essential for pesticide management and food safety.


The study involves the analysis of peach peel samples subjected to treatments with three different types of pesticides: Akivi-treated samples (botanical pesticide), Armicarb®-treated samples (mineral extract), and Chemical reference-treated samples (chemical pesticides). Untreated control samples were also collected for comparison.

Technological Methods

Exometabolomic Framework (EMF): The EMF is employed to study the fate of pesticide compounds in peach peel samples. It involves several steps:

  • Detection and Separation: Pesticide xenometabolites are detected and separated from the endometabolites of peaches.
  • Temporal Tracking: The temporal evolution of pesticide xenometabolites is monitored over multiple time points after treatment.
  • Statistical Analysis: Statistical methods, including Principal Component Analysis (PCA) and Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA), are used to discern patterns and trends in pesticide degradation and persistence.

Analytical Techniques: High-resolution mass spectrometry is employed to detect and quantify xenometabolites. The analysis includes the use of a C18 Reverse-Phase LC (RPLC) column to separate and identify compounds.

Quantification: Quantification of pesticide active substances (AS) and xenometabolites is performed, and the results are compared to regulatory thresholds to assess pesticide residue levels.


Akivi Treatment: Akivi botanical extract showed a dissipation pattern in the peach samples over time. Some features associated with the extract disappeared, but complete residue dissipation was not observed. PCA analysis revealed distinctions between different time points and treatments.

Armicarb Treatment: While the mineral AS (KHCO3) of Armicarb could not be detected due to its high solubility, the EMF approach successfully identified certain xenometabolites associated with Armicarb. These compounds persisted throughout the study.

Chemical Reference Treatment: The study detected and quantified the ASs of the chemical pesticides in the treated samples, as well as some by-products. Discrimination between treated and untreated samples was possible, despite contamination of the untreated control samples. Persistence of ASs and degradation patterns of by-products were observed.

Contamination Issues: The study highlighted the challenge of contamination in field experiments, particularly through spray drift. This contamination impacted the untreated control samples and should be addressed in future research.

Variability: Field conditions introduced variability in the study, including variations in pesticide exposure and environmental factors. To mitigate this, improvements in sampling strategies and replication are suggested.
