“…The concentration and types of alkaloids observed vary significantly, due to pollen origin diversity, with tertiary heterocyclic amines and their related N-oxide form being the two main forms of these alkaloids. It has been found in several analyzed samples, for example, the presence of echinatine N-oxides and rinderine N-oxide [52], trichodesmine [53], or echimidine and echimidin N-oxid [54] (Figure 6). The concentration and types of alkaloids observed vary significantly, due to pollen origin diversity, with tertiary heterocyclic amines and their related N-oxide form being the two main forms of these alkaloids.…”

Pollen, a remarkably versatile natural compound collected by bees for its abundant source of proteins and nutrients, represents a rich reservoir of diverse bioactive compounds with noteworthy chemical and therapeutic potential. Its extensive biological effects have been known and exploited since ancient times. Today, there is an increased interest in finding natural compounds against oxidative stress, a factor that contributes to various diseases. Recent research has unraveled a multitude of biological activities associated with bee pollen, ranging from antioxidant, anti-inflammatory, antimicrobial, and antifungal properties to potential antiviral and anticancer applications. Comprehending the extensive repertoire of biological properties across various pollen sources remains challenging. By investigating a spectrum of pollen types and their chemical composition, this review produces an updated analysis of the bioactive constituents and the therapeutic prospects they offer. This review emphasizes the necessity for further exploration and standardization of diverse pollen sources and bioactive compounds that could contribute to the development of innovative therapies.

“…In the last 3 years, food alerts related to these products have only been notified for high levels of PAs found in pollen (Rapid Alert System for Food and Feed, 2023). Nonetheless, within this period, many authors have addressed the determination of TAs and PAs in honey and pollen samples (Gottschalk et al, 2020;He et al, 2020;Moreira et al, 2020;Romera-Torres et al, 2020;Thompson et al, 2020;Bandini and Spisso, 2021;Valese et al, 2021;Schlappack et al, 2022a;Schlappack et al, 2022b;Guo et al, 2022;Jansons et al, 2022;Kowalczyk and Kwiatek, 2022;Kwon et al, 2022;Martinello et al, 2022;Rizzo et al, 2022;Rizzo et al, 2023a;Peloso et al, 2023;Roncada et al, 2023;Casado et al, 2024b). The results achieved in these works have revealed these products are frequently contaminated with these toxins, detecting levels of PAs and TAs in wide range (0.012-3313 μg/kg).…”

“…For the extraction of these toxins from this type of matrices, most authors have first dissolved the samples in 0.05 M H 2 SO 4 , since it helps to release the analytes from the matrix and decrease the sample viscosity. Afterwards, for sample purification, different conventional sample preparation procedures have been employed, being SPE the most widely used, followed by QuEChERS (Gottschalk et al, 2020;He et al, 2020;Moreira et al, 2020;Romera-Torres et al, 2020;Schlappack et al, 2022a;Schlappack et al, 2022b;Guo et al, 2022;Jansons et al, 2022;Kowalczyk and Kwiatek, 2022;Kwon et al, 2022;Martinello et al, 2022;Peloso et al, 2023;Roncada et al, 2023). For SPE, cartridges with cationexchange sorbents (e.g., MCX, SCX) have been preferred.…”

The food control of tropane and pyrrolizidine alkaloids has become in recent years in Europe one of the main priorities within the food safety field due to the exponential increase in food alerts related to the concerning levels of these natural toxins in foods. This awareness has led to increasing progress in the research and determination of these compounds. Hence, this mini-review provides a brief and comprehensive overview of the evolution of these food alerts, highlighting the main food products frequently contaminated with these alkaloids and reviewing the analytical advances in their determination within the las 3 years (from 2020 to 2023).
