Worldwide, there are plants known as psychoactive plants that naturally contain psychedelic active components. They have a high concentration of neuroprotective substances that can interact with the nervous system to produce psychedelic effects. Despite these plants' hazardous potential, recreational use of them is on the rise because of their psychoactive properties. Early neuroscience studies relied heavily on psychoactive plants and plant natural products (NPs), and both recreational and hazardous NPs have contributed significantly to the understanding of almost all neurotransmitter systems. Worldwide, there are many plants that contain psychoactive properties, and people have been using them for ages. Psychoactive plant compounds may significantly alter how people perceive the world.

Herbal infusions are among the most contaminated food commodities; however, the fate of TAs after ingestion remains poorly understood. This study presents a comprehensive investigation into the absorption, and metabolism of five TAs (atropine, scopolamine, tropine, homatropine, and apoatropine) following the digestion of contaminated tea. In vitro human cell models were employed, including gastric (NCI-N87), intestinal (Caco-2:HT29-MTX), and hepatic (HEP-G2) cells. TAs were found to be highly absorbed in the intestinal epithelium, while gastric cells exhibited poor absorption. Metabolism was studied using a custom-made database, revealing that it occurs predominantly in intestinal cells, involving hydroxylation and methylation reactions. Cell metabolomics was conducted using annotation, fragment simulation, and statistical software platforms. Significant statistical differences were observed for 40 tentatively identified compounds. MetaboAnalyst 5.0 was employed to discern the most disturbed metabolic pathways, with amoniacids biosynthesis pathways and TCA cycles being the most affected. These pathways are involved in responses to cellular metabolic stress, neurotransmitter production, cellular energy generation, and the regulation of oxidative stress response. The findings of this study enhance our understanding of the fate of TAs after ingestion, their metabolization and their effects at the cellular level. Copyright © 2024 Elsevier B.V.

(3)Neuchâtel Platform of Analytical Chemistry (NPAC), University of Neuchâtel, Neuchâtel 2000, Switzerland. The Solanaceae plant family contains at least 98 genera and over 2700 species. The Duboisia genus stands out for its ability to produce pyridine and tropane alkaloids, which are relatively poorly characterized at the phytochemical level. In this study, we analyzed dried leaves of Duboisia spp. using supercritical CO2 extraction and ultra-high-pressure liquid chromatography coupled to high-resolution tandem mass spectrometry, followed by feature-based molecular networking. Thirty-one known tropane alkaloids were putatively annotated, and the identity of six (atropine, scopolamine, anisodamine, aposcopolamine, apoatropine, and noratropine) were identified using reference standards. Two new granatane alkaloids connected in the molecular network were highlighted from Duboisia myoporoides, and their α-granatane tropate and α-granatane isovalerate structures were unambiguously established by semisynthesis.

In this study, an indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) based on a broad-spectrum monoclonal antibody for tropane alkaloids (TAs) was established for the rapid screening of atropine, scopolamine, homatropine, apoatropine, anisodamine, anisodine and L-hyoscyamine residues in pig urine, pork and cereal flour samples through a simple sample preparation procedure. The half inhibitory concentrations of atropine, homatropine, L-hyoscyamine, apoatropine, scopolamine, anisodamine and anisodine were 0.05, 0.07, 0.14, 0.14, 0.24, 5.30 and 10.15 ng mL-1, respectivelyThe detection and quantitative limits of this method for TAs in samples were 0.18-73.18 and 0.44-74.77 μg kg-1. The spiked recoveries ranged from 69.88% to 147.93%, and the coefficient of variations were less than 14%. Good correlation (R2 = 0.9929) between the results of the ic-ELISA and the high performance liquid chromatography-tandem mass spectrometry support the reliability of the developed ic-ELISA method.

Electronic address: agarrido@ual.es. Cereal based foods are a major part of the infant diet and they can be contaminated with Solanaceae and other plants containing tropane alkaloids. This study was focused on the optimisation of an extraction procedure based on a solid-liquid method and an online SPE system, directly coupled to different mass spectrometry analysers as Orbitrap and triple quadrupole (QqQ), removing the chromatographic separation step. Total running analysis time was 15.8 min (17.3 min in the QqQ system). The developed method was validated obtaining recoveries ranging from 66 to 98% and 68-97% for the Orbitrap and QqQ respectively (RSD lower than 14.3%) and limits of quantification from 0.5 to 5 µg kg-1 and 0.5-10 µg kg-1 for the QqQ and Orbitrap analyser respectively. The validated method was applied to several cereal based baby food samples, finding a positive sample containing atropine (11.5 µg kg-1), scopolamine (2.8 µg kg-1) and apoatropine (7.5 µg kg-1).

Marín-Sáez J(1), Romero-González R(1), Garrido Frenich A(1), Egea-González FJ(1). Author information: (1)Department of Chemistry and Physics, Analytical Chemistry Area, University of Almería, Research Centre for Agricultural and Food Biotechnology (BITAL), Agrifood Campus of International Excellence ceiA3, Almería, Spain. Homeopathic products are still a controversial issue in modern medicine, understood as complementary or alternative medicine (CAM). In this particular case, homeopathic products prepared from Atropa belladonna extracts may present specific problems due to the effects derived from its components. This article applies a simple, rapid, reliable method to the analysis of different homeopathic products obtained from Atropa belladonna; drugs containing high concentration of plant extracts; and Atropa belladonna seeds. The method was based on a simple solid-phase preconcentration method followed by ultra-high pressure liquid chromatography (UHPLC) coupled to high resolution mass spectrometry using Exactive-Orbitrap as an analyser. An in-house database was set and atropine and scopolamine were the compounds detected at highest concentrations in homeopathic products from Atropa belladonna extracts (4.57 and 2.56 μg/kg, respectively), in Belladonna ointment (4007 and 1139 μg/kg, respectively) and Belladonna seeds (338 and 32.1 mg/kg, respectively). Other tropane alkaloids such as tropine, apoatropine, aposcopolamine, tropinone, homatropine, and anisodamine were detected at lower concentrations (0.04-1.36 μg/kg). When untargeted analysis was performed, other tropane alkaloids were identified in the tested samples, such as ecgonine (0.003 μg/kg), benzoylecgonine (0.56 μg/kg), calystegines A (19.6 μg/kg), B (33.1 μg/kg), and C (1.01 μg/kg). Finally other compounds present in the homeopathic products, such as sugars (fructose, glucose, and lactose) or amino acids (valine, ornithine, leucine, and phenylalanine), were identified.
