Naturally occurring toxins are an unavoidable reality of today’s global food supply, and among them, alkaloids represent one of the most analytically challenging and safety‑critical compound classes. Produced by plants as natural defence mechanisms, alkaloids can unintentionally enter food through contamination, co‑harvesting, or adulteration, posing serious risks to consumer health and regulatory compliance.
From pyrrolizidine alkaloids (PAs) in herbal teas and honey, to tropane alkaloids in cereal‑based foods, and highly toxic Aconitum alkaloids in adulterated spices, food testing laboratories are under increasing pressure to detect these compounds reliably, sensitively, and at scale.
SCIEX works closely with food safety laboratories worldwide to help meet these challenges, delivering robust LC‑MS/MS solutions, validated workflows, and application‑driven support for alkaloid testing across diverse food matrices.
Understanding Alkaloids and their risk in food
Alkaloids are nitrogen‑containing secondary metabolites produced by many plant species. While they play a defensive role in nature, certain alkaloids are hepatotoxic, genotoxic, neurotoxic, or cardiotoxic when consumed by humans.
Food contamination can occur in several ways:
Regulatory bodies, particularly in the EU, have responded with increasingly strict maximum levels and defined analytical requirements for plant toxins, including pyrrolizidine and tropane alkaloids.
Pyrrolizidine alkaloids: Sensitivity and selectivity are essential
Pyrrolizidine alkaloids have received heightened regulatory attention due to their documented liver toxicity and carcinogenic potential. They are commonly found in herbal infusions, teas, honey, and leafy vegetables, often at trace levels that are difficult to measure accurately.
Analytically, PAs present a unique challenge:
SCIEX has demonstrated highly selective LC‑MS/MS workflows for PA analysis using SelexION™ differential mobility technology, enabling laboratories to distinguish isomeric compounds that cannot be resolved by conventional LC‑MS/MS alone. These methods support sensitive quantification of EFSA‑recommended PAs in complex herbal matrices. [sciex.com]

Tropane alkaloids and mycotoxins: Multi‑residue efficiency without compromise
Tropane alkaloids such as atropine and scopolamine are another class of plant toxins of concern, particularly in cereals, baby food, and grain‑based products. Their presence is often linked to the unintended inclusion of toxic plants growing near crops.
Modern food laboratories increasingly require multi‑residue methods that can detect tropane alkaloids alongside other contaminants such as mycotoxins, without sacrificing sensitivity or throughput.

Aconitum alkaloids: Rapid detection in high‑risk adulteration cases
Few alkaloids illustrate the importance of analytical vigilance more clearly than Aconitum alkaloids, such as aconitine. These compounds are extremely toxic and have been implicated in food poisoning incidents linked to spice adulteration and misidentification, particularly in powdered products.
A rapid LC‑MS/MS method for the determination of Aconitum alkaloids in adulterated spice powders has been developed, demonstrating:
Such approaches enable food testing laboratories to respond quickly and decisively when adulteration is suspected, supporting both public health protection and regulatory investigations.
The role in supporting food testing laboratories
Across all alkaloid classes, our approach is built on real-world laboratory needs:
Through its natural toxins testing portfolio, SCIEX supports laboratories analysing alkaloids, mycotoxins, marine biotoxins, and other plant-derived contaminants—helping ensure safe food supplies across global markets.

Looking ahead: Confident alkaloid testing in a changing food landscape
As climate change, global trade, and complex supply chains continue to influence food contamination patterns, alkaloid testing will remain a critical focus for food safety laboratories. Reliable detection at ultra‑trace levels, combined with confident identification, is essential to protect consumers and maintain regulatory trust.
By pairing advanced LC‑MS/MS technology with application‑driven expertise, SCIEX continues to enable food laboratories to meet today’s challenges—and prepare for those still to come.

Waterproof jackets. Stain-resistant shoes. Easy-clean fabrics are marketed as “performance.” Behind those everyday claims sits a class of chemicals now reshaping regulation, brand accountability, and laboratory science: PFAS.
For decades, SCIEX has been part of bioanalytical innovation, empowering scientists in pharma and biopharma to push the boundaries of sensitivity, accuracy, and throughput. Across complex workflows and increasingly challenging therapeutic modalities.
Trifluoroacetic acid (TFA) is emerging as one of the most concerning ultrashort-chain PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
