RESUMO
The opium poppy (Papaver somniferum) is a global commercial crop that has been historically valued for both medicinal and culinary purposes. Naturally occurring opium alkaloids including morphine, codeine, thebaine, noscapine, and papaverine are found primarily in the latex produced by the plant. If the plant is allowed to fully mature, poppy seeds that do not contain the opium alkaloids will form within the pods and may be used in the food industry. It is possible for the seeds to become contaminated with alkaloids by the latex during harvesting, posing a potential health risk for consumers. In the USA, there have been more than 600 reported adverse events including 19 fatalities that may be linked to the consumption of a contaminated poppy-containing product such as home-brewed poppy seed tea. Unwashed poppy seeds and pods may be purchased over the Internet and shipped worldwide. The Forensic Chemistry Center, US Food and Drug Administration (FDA) has evaluated several mass spectrometers (MS) capable of rapid screening to be used for high-throughput analysis of samples such as poppy seeds. These include a direct analysis in real-time (DART) ambient ionization source coupled to a single-quadrupole MS, an atmospheric solids analysis probe (ASAP) ionization source coupled to the same MS, and ion mobility spectrometers (IMS). These instruments have been used to analyze 17 poppy seed samples for the presence of alkaloids, and the results were compared to data obtained using liquid chromatography with mass spectral detection (LC-MS/MS). Results from the 17 poppy seed samples indicate that the DART-MS, ASAP-MS, and IMS devices detect many of the same alkaloids confirmed during the LC-MS/MS analyses, although both the false-positive and false-negative rates are higher, possibly due to the non-homogeneity of the samples and the lack of chromatographic separation.

BACKGROUND: Oligo-astheno-teratozoospermia (OAT) syndrome is one of the causes of male infertility, characterized by a decreased number of sperms (oligospermia), poor sperm motility (asthenospermia), and abnormal sperm shape (teratospermia). In necrospermia, spermatozoa in the ejaculated semen are dead, and in hypospermia, semen volume is less than 2 mL. The present case may be unique because of the association of all these features together in a single patient. METHOD: This idiopathic case was treated, from November 2016 to April 2017 in the National Homeopathy Research Institute in Mental Health, with the homeopathic medicine Natrium muriaticum. The Modified Naranjo Criteria for Homeopathy (MONARCH) score was used to assess the likelihood of causal attribution of the clinical outcome to the homeopathic medicine. RESULT: By the third month of starting homeopathic treatment, there was a marked improvement in sperm count from 14.4 to 77.4 million, semen volume from 0.8 to 2.2 mL, and normal forms from 14 to 75%. His wife became pregnant by the 5th month and delivered a healthy baby girl at full term. A MONARCH score of +9/13 indicates a positive causal relationship between the medicine prescribed and the treatment outcome. CONCLUSION: The present case report suggests a positive effect of individualized homeopathic medicine in treating a rare presentation of male infertility due to OAT syndrome.

BACKGROUND: Polycrystalline structures formed inside evaporating droplets of different biological fluids have been shown sensitive towards various influences, including ultra high dilutions (UHDs), representing so a new approach potentially useful for basic research in homeopathy. In the present study we tested on a wheat seed model Zincum metallicum 30c efficacy versus lactose 30c and water. MATERIALS AND METHODS: Stressed and non-stressed wheat seeds were watered with the three treatments. Seed-leakage droplets were evaporated and the polycrystalline structures formed inside the droplet residues were analyzed for their local connected fractal dimensions (LCFDs) (measure of complexity) using the software ImageJ. RESULTS: We have found significant differences in LCFD values of polycrystalline structures obtained from stressed seeds following the treatments (p<0.0001); Zincum metallicum 30c lowered the structures' complexity compared to lactose 30c and water. In non-stressed seeds no significant differences were found. CONCLUSIONS: The droplet evaporation method (DEM) might represent a potentially useful tool in basic research in homeopathy. Furthermore our results suggest a sensitization of the stressed model towards the treatment action, which is conforming to previous findings.

BACKGROUND: Anaphylaxis during anaesthesia is fatal in 3-9% of patients and analgesics, including opioids, and is the second most common medicament-related cause, although the prevalence is underestimated. We recently found that patients may generate IgE antibodies to opium seeds. OBJECTIVES: To determine the diagnostic accuracy of specific antibodies to morphine, codeine, rocuronium and oil body and aqueous fractions of Papaver somniferum seeds in the diagnosis and prevention of allergy to opioids. METHODS: Patients with hypersensitivity reactions during surgery, and severe clinical allergy (pollen, tobacco), and illicit heroin users were selected. The sensitivity, specificity and predictive values of in vivo and in vitro diagnostic techniques including oil body and aqueous fractions of P. somniferum seeds were measured. RESULTS: We studied 203 patients, with mean age 35.1±17.1 and 200 healthy controls. Patients sensitised to heroin or with hypersensitivity reactions during surgery responded to P. somniferum seed tests. Of patients not known to be sensitised to opioids, the highest positivity was in patients sensitised to tobacco (p<0.001). Opium seed skin tests and IgE, especially the oil body fraction, were more sensitive (64.2%) and specific (98.4%) than morphine, codeine and rocuronium tests for opioid sensitivity. Pollen allergy was not a risk factor for sensitisation to morphine. CONCLUSIONS: Sensitivity to opioids and intraoperative anaphylaxis can be diagnosed by routine tests. IgE and skin tests for the oil body fraction of P. somniferum had the highest sensitivity for sensitisation to opioids.

BACKGROUND: The diagnosis of anaphylactic reactions due to opiates during anaesthesia can be difficult, since in most cases various drugs may have been administered. Detection of specific IgE to poppy seed might be a marker for sensitisation to opiates in allergic people and heroin-abusers. This study assessed the clinical value of morphine, pholcodine and poppy seed skin-prick and IgE determination in people suffering hypersensitivity reactions during anaesthesia or analgesia and drug-abusers with allergic symptoms. METHODS: We selected heroin abusers and patients who suffered severe reactions during anaesthesia and analgesia from a database of 23,873 patients. The diagnostic yield (sensitivity, specificity and predictive value) of prick and IgE tests in determining opiate allergy was analysed. RESULTS: Overall, 149 patients and 200 controls, mean age 32.9 ± 14.7 years, were included. All patients with positive prick to opiates showed positive prick and IgE to poppy seeds, but not to morphine or pholcodine IgE. Among drug-abusers, 13/42 patients (31%) presented opium hypersensitivity confirmed by challenge tests. Among non-drug abusers, sensitisation to opiates was higher in people allergic to tobacco (25%), P<.001. Prick tests and IgE against poppy seed had a good sensitivity (95.6% and 82.6%, respectively) and specificity (98.5% and 100%, respectively) in the diagnosis of opiate allergy. CONCLUSIONS: Opiates may be significant allergens. Drug-abusers and people sensitised to tobacco are at risk. Both the prick and specific IgE tests efficiently detected sensitisation to opiates. The highest levels were related to more-severe clinical profiles.

BACKGROUND: The 2,4-D (2,4-dichlorophenoxyacetic acid) is using as a growth regulator in tissue culture media. Maize seeds have poor ability to maintain germination rate in the long term. OBJECTIVE: To examine the possible restorative effect of homeopathic 2,4-D potencies on maize seedlings originating from seeds damaged by accelerated aging. METHODS: Seeds of four maize lines were subjected to accelerated aging stress treatment. Seed samples were treated with distilled water (control) and a range of potencies of 2,4-D: 3C, 3.75C, 4.5C, 5.25C and 6C. The germination capacity, fresh substance (FS) and length of root and shoot were determined. Hydrolysis and biosynthesis, GSH/GSSG ratio and redox capacity were calculated. RESULTS: Induced seed aging decreased germination rate and growth of seedlings. 2,4-D potencies did not have a statistically significant effect on germination. However, there were statistically significant effects on FS production, root and shoot length and redox capacity. The 3C potency had the largest effect on the FS accumulation, 4.5C increased root and shoot length, compared to control (statistically significant). The GSH/GSSG ratio and the redox capacity were decreased by aging. The 3C and 4.5C potencies tended to reverse the GSH/GSSG ratio (statistically significant) in the root and shoot, (i.e., shifted the redox balance to the reduced state). CONCLUSION: Homeopathic potencies of 2,4-D appear to have a beneficial effect on artificially aged maize seeds: they stimulate growth through better substance conversion from seed rest, and shift the redox capacity towards a reduced environment. Further work is required to determine if this is an useful means of improving maize seed germination and growth.

Domesticated opium poppy Papaver somniferum L. subsp. somniferum probably originated in the Western Mediterranean from its possible wild progenitor, Papaver somniferum L. subsp. setigerum and spread to other European regions. Seeds of opium poppy have been identified in different European regions since the Early Neolithic (from the 6th millennium cal. BC onwards) period. However, until recently, the absence of morphological identification criteria has prevented the discrimination between wild and domestic morphotypes. New morphometric approaches to distinguish modern subspecies have been proven to be applicable to waterlogged archaeological remains, opening the possibility of understanding the process of domestication of the plant in both time and space. This paper applies seed outline analyses, namely elliptic Fourier transforms, combined with size and number of cells to archaeological waterlogged Papaver seeds throughout the Neolithic period in the NW Mediterranean and the surroundings of the Alps. Furthermore, one example from the Late Bronze Age (LBA) was added to see what kind of differences appeared during the >1000 years between the end of the Neolithic and the LBA. The aim of the study is to classify the archaeological seeds as domestic or wild morphotypes and observe morphometric changes in connection to geographical and chronological patterns that can explain the spread and domestication process(es) of this important crop. A total of 295 archaeological seeds coming from 10 waterlogged sites dating between 5300-2300 cal. BC (Neolithic), and one LBA site dating to 1070 cal. BC were analysed. The results indicate the presence of seeds, similar to the wild morphotype, in the Mediterranean sites and larger seeds, similar to the domestic morphotype, in the regions surrounding the Alps. The number of cells mainly increased during the Late Neolithic (3300 to 2300 cal. BC) and, finally, in the Late Bronze Age (ca. 1050-800 cal. BC), larger, morphologically domesticated seeds are clearly predominant. A change in the shape of the seeds is only clearly visible in the LBA material. Altogether our results suggest that opium poppy seeds show no sign of domestication in the early periods of the Neolithic, despite the fact that the plant was very probably already cultivated at that time in the western Mediterranean region.

BACKGROUND Unwashed or unprocessed poppy seeds may be an underrecognized substance that can lead to dependence, abuse, and an opioid use disorder. Poppy seeds can be purchased in an unwashed or unprocessed form, and these seeds can be contaminated with the opium alkaloids morphine, codeine, and thebaine on their surfaces. Poppy seeds that are commercially available, such as those used for baking and in other food products, are legal to purchase, as they do not contain the opium alkaloids on their seed coats. Purchase and possession of the unwashed or unprocessed seeds are not legal in the United States. These contaminated poppy seeds can then be put through a process in which they are washed, and the supernatant (tea) is collected and consumed to experience its intoxicating effect or for the treatment of pain or opioid withdrawal. CASE REPORT A 65-year-old man with a history of alcohol use disorder, cannabis use, and chronic pain began using this poppy seed tea for treatment of chronic pain after his provider had stopped prescribing opioid pain medications for him. He developed a dependence on the tea. He had reached out for assistance as it was his desire to stop using the poppy seed tea. The diagnosis of an opioid use disorder was made using the DSM-V criteria. He was successfully induced and maintained on a buprenorphine/naloxone product. CONCLUSIONS Poppy seeds in their unwashed and unprocessed form can be misused and could lead to an opioid use disorder. This disorder can be treated with buprenorphine/naloxone products.

INTRODUCTION: Poppy seed tea is used for its opioid effects and contains multiple opium alkaloids, including morphine, codeine, papaverine, and thebaine. Animal studies indicate thebaine has strychnine-like properties, but there is limited literature describing human thebaine poisoning. We describe a cluster of acute thebaine poisoning in people ingesting tea made using poppy seeds with high thebaine content that entered the Australian food supply chain. METHODS: This is an observational study of patients poisoned after drinking poppy seed tea. Cases were identified by three prospective toxicovigilance systems: the Emerging Drug Network of Australia collaboration, the New South Wales Prescription, Recreational and Illicit Substance Evaluation program, and the Emerging Drugs Network of Australia Victoria study. We report characteristics of clinical toxicity in cases with reported ingestion of poppy seed tea and analytical confirmation of thebaine exposure. RESULTS: Forty cases presenting with multi-system toxicity following poppy seed tea ingestion were identified across seven Australian states/territories from November 2022 to January 2023. Blood testing in 23 cases confirmed high thebaine concentrations. All 23 were male (median age 35, range 16-71 years). All patients experienced muscle spasms. Rigidity was described in nine, convulsions in six, while rhabdomyolysis, acute kidney injury, and metabolic acidosis occurred in five patients. There were two cardiac arrests. The thebaine median admission blood concentration was 1.6 mg/L, with a range of 0.1-5.6 mg/L, and was the dominant opium alkaloid in all samples. Convulsions, acute kidney injury, metabolic acidosis, and cardiac arrest were associated with increasing median thebaine concentrations. Four patients were managed in the Intensive Care Unit, with two receiving continuous kidney replacement therapy (one also received intermittent haemodialysis) for kidney injury. There was one death. CONCLUSIONS: Thebaine toxicity, like strychnine poisoning, resulted in neuromuscular excitation characterized by muscle spasm, rigidity, and convulsions. Severe toxicity, including acute kidney injury, metabolic acidosis, and cardiac arrest, appears dose-dependent.

BACKGROUND: Ignatia amara (Ignatia), a remedy made from the Strychnos ignatii seeds, is used for anxiety-related symptoms, but consistent evidence of its activity in reproducible experimental models is lacking. An investigation was performed in order to assess on mice, by means of emotional response models, the activity of homeopathic Ignatia dilutions/dynamizations. METHODS: Groups of 8 mice of the CD1 albino strain were treated intraperitoneally for 9 days with 0.3ml of five centesimal (C) dilutions/dynamizations of Ignatia (4C, 5C, 7C, 9C and 30C). Control mice were treated with the same hydroalcoholic (0.3%) solution used to dilute the medicines. Diazepam (1mg/kg) was the positive reference drug. Validated test models for locomotion and emotional response, the Open-Field (OF) and the Light-Dark (LD) tests, were employed. Five replications of the same protocol were carried out, in a randomised way using coded drugs/controls. RESULTS: In the OF the general locomotion of mice was slightly decreased by Ignatia 4C, but not by Ignatia 5C, 7C, 9C and 30C, indicating the absence of unspecific motor impairment or sedation by these dilutions/dynamizations. Ignatia and diazepam seemed to decrease the number of urine spots released in the OF during 10min, with borderline significance (P=0.083). In the LD the tested medicine showed anxiolytic-like activity (increase of time spent and distance travelled in the lit area), though to a lesser extent than diazepam. The highest and most significant difference with untreated controls (P<0.01) was observed with the 9C dilution/dynamization. Among the 5 replication experiments, the best drug effects were obtained where the baseline anxiety of mice was higher. CONCLUSIONS: Homeopathic Ignatia dilutions/dynamizations (peak at 9C) modify some emotion-related symptoms in laboratory mice without affecting locomotion.

Bakery products containing poppy seeds are increasingly being commercialized. These seeds may be contaminated with latex from the Papaver somniferum L. plant rich in opium alkaloids (OAs). Therefore, health authorities demand the development of analytical methods to control them. In this study, an efficient and simple method was developed and validated for the first time to analyze six OAs in bakery products by high-performance liquid chromatography-tandem mass spectrometry. For this purpose, a solid-liquid extraction was optimized, and then a magnetic material [magnetite surface-modified with Fe(III) terephthalate, denoted as Fe3O4@TPA-Fe] was used for a fast magnetic solid-phase extraction. The method has been validated with adequate recoveries (70-110%) and relative standard deviations (<20%) and without matrix effects. Nine bakery samples (five breadsticks and four sliced bread) were analyzed; breadsticks showed low amounts of OAs, but two sliced bread showed higher amounts of OAs than the new amount (1.5 mg/kg) set by the Commission Regulation (EU) 2021/2142.

Laboratories are challenged to distinguish whether a positive urine morphine result is due to heroin use or possible poppy seed consumption. Thebaine is an opium alkaloid that has been shown to be present in the urine of individuals who have consumed poppy seeds, as well as those who have used opium. It is not present in heroin. We present a sensitive, specific liquid chromatography tandem mass spectrometry (LC-MS/MS) assay for thebaine. We show that thebaine is detectable after consumption of two different poppy seed-containing products for up to 72 h in urine. We discuss limitations of the assay and suggest how the test might best be used.

INTRODUCTION: The St. Ignatius bean of the Strychnos ignatii tree and Nux Vomica homeopathic products presumably could contain the toxic alkaloids strychnine and brucine. This study aimed to determine the amount of these toxic alkaloids in some commercially available Nux Vomica products and the St. Ignatius bean and to determine if overdose of these products could result in clinically significant toxicity. METHODS: Using ultra-performance liquid chromatography-tandem mass spectrometry, various formulations of Nux Vomica products and St. Ignatius beans were analyzed for strychnine, and brucine with detection limits set at 0.1 ng/g. RESULTS: None of the analyzed Nux Vomica products contained any detectable strychnine or brucine, while the expected strychnine dose from a St. Ignatius bean would be < 0.001 mg. CONCLUSIONS: Overall, our study reveals that the amount of strychnine in homeopathic Nux Vomica products or St. Ignatius beans are not likely to result in clinically significant strychnine toxicity.

Fens are among the most threatened habitats in Europe as their area has decreased considerably in the last centuries. For successful management and restoration conservationists need detailed knowledge about seed bank formation and seed longevity of plants, as these features are closely related to successional and vegetation dynamical processes. I analysed seed longevity and the germination characteristics of six fen plant species by seed burial experiments. Based on seed weight, seed bank was expected for long-term persistent for the light-seeded Schoenus nigricans, Carex appropinquata, C. pseudocyperus, C. davalliana and Peucedanum palustre and also that for the medium-seeded Cicuta virosa. It was proved that, the latter two species have short-term persistent seed banks, while Carex pseudocyperus has a transient seed bank, therefore these species may only have a limited role in restoration from seed banks. It was found that Schoenus nigricans, Carex appropinquata and C. davalliana have persistent seed banks, because some of their four-year-old seeds have emerged. Fresh seeds had low germination rate in all studied species and majority of seeds emerged after winter, except for Carex pseudocyperus. After the germination peak in spring, the majority of the ungerminated seeds of Schoenus nigricans, Peucedanum palustre, Carex appropinquata, C. davalliana and Cicuta virosa entered a secondary dormancy phase that was broken in autumn. I found the seasonal emergence of the latter three species highly similar.

Limited information exists on the effectiveness of potential treatments to reduce levels of opium alkaloids that may be present in seeds from poppy (Papaver somniferum L.). Poppy seeds containing morphine at relatively lower (14.7 mg kg-1) and higher (210.0 mg kg-1) concentrations were subjected to dry heat and steam treatments, water washing, and baking. Sample extracts were then analyzed using liquid chromatography-tandem mass spectrometry for the opium alkaloids morphine, codeine, and thebaine. The results indicated that thermal treatment promoted opium alkaloid degradation in poppy seed samples, with a 50% loss of morphine observed after 30-40 min at 200 °C. Water washing reduced concentrations of opium alkaloids in poppy seeds by approximately 50-80%, while steam treatment resulted in reduction of morphine in only one sample type. Importantly, baking had no significant effect on concentrations of opium alkaloids. Overall, these results indicate that opium alkaloids may not be significantly affected by baking or steam application and that poppy seeds may require water washing or extended thermal treatment to promote reduction of these compounds.

According to the European Pharmacopoeia monograph 1038 (Praeparationes homoeopathicae), homeopathic preparations are produced by successive dilution and succussion steps. Dilution levels beyond Avogadro's limit, however, render specific effects implausible according to standard scientific knowledge. Accordingly, we were interested in a critical empirical investigation of preparations produced according to this monograph. Within a precursor study we developed a bioassay based on a fingerprint metabolomic analysis of Lepidium sativum seeds germinated in vitro in either homeopathic preparations or controls in a blinded and randomized assignment. Results of the precursor study were not consistent with the hypothesis that the effects of a Stannum metallicum 30x preparation are identical to placebo. In the present study we investigated the reproducibility of these effects after scrutinizing and optimizing experimental procedures. Ten independent experiments were performed in a blinded and randomized assignment in two independent laboratories. Additionally, 10 systematic negative water control experiments were performed in both laboratories to critically assess the stability of the experimental set-up. The effects of the Stannum metallicum 30x treatment were reproduced. The systematic negative control experiments did not yield false-positive results, indicating a stable experimental set-up. We thus repeatedly observed biological effects conflicting with the assumption that Stannum metallicum 30x is identical to placebo. We therefore wish to discuss whether these findings are to be considered a scientific anomaly or whether they might stimulate further investigations to clarify whether application of the European Pharmacopoeia monograph 1038 may result in pharmaceutical preparations with specific effects.

Opium is a substance extracted from Papaver somniferum L that is chronically abused specially in the traditional production regions. Reports on opium poisoning has largely disappeared from the occidental literature on drug problems but recent scientific articles show cases of death related to opium in industrialized countries. This fact led us to consider the interest of knowing the state of the art of acute opium intoxication in modern times. This work shows a compilation of these uncommon cases occurred in different settings and circumstances. Data were obtained by a computer assisted search of the literature using the key words "opium poisoning", "poppy", "poppy seeds", and "papaver somniferum" in PubMed, accompanied by a hand search of the reference lists of all articles for any relevant studies not included in the database. In addition, Google Scholar, government reports, and cases adequately documented on websites were reviewed. Type 1 cases, Accidental opium intoxications when it is used as a recreational drug: Reported cases came mainly from industrialized countries. They were mostly male with a range age of 17-64 years. Many had antecedents of alcoholism or drug abuse and opium tea was used as a substitute of heroin. Rachacha has caused poisonings in France and has been detected in a stash in Spain. Toxicological analysis was documented in forensic cases. The danger of this renewed interest in opium is exemplified in that many of the poisoning cases resulted in fatalities. Type 2 cases, Accidental opium intoxications in children or adults when it used as folk remedy: Pediatric intoxication after the use of opium as folk remedy are mainly published in traditional opium-producing areas with a long history of use or ethnic communities in England or USA. Addiction to opium was common among relatives. Type 3 cases, Opium intoxications with poppy seeds consumed as food: Due to excessive consumption of opium seeds as food, sporadic cases of mild toxicity had been reported and morphine contents were documented. Type 4 cases: Accidental opium intoxications when using the abdominal or pelvic cavity for concealing the drug: Accidental opium body packer intoxications are seen in patients who traveled from illegal opium areas of production. Type 5 cases: Suicides by opium: Opium was a prevalent agent among cases of suicides in Iran but data are scarce.

Toxic and Potent Chinese Materia Medica (T/PCMM) are being used more and more in the treatment of various diseases. In view of their toxic side effects and to ensure their safe use, accurate and reliable authentication is indispensable. However, identifying characteristics of T/PCMM are seldom reported, even though modern microscopy can provide ample, unique identifying characteristics from cells found in transverse sections and powders. In particular, no systematic authentication studies on seed T/PCMM have been conducted. In the course of our study on 31 T/PCMM originating from plants, animals, minerals, and secreta, an accurate and convenient method, based on microscopic techniques, has been developed and reported for the authentication of animal T/PCMM. The present study deals with detailed investigations on three species of seed T/PCMM, namely Semen Hyoscyami (Hyoscyamus niger L.), Semen Euphorbiae (Euphorbia lathyris L.), and Semen Strychni (Strychnos nux-vomica L.). The macroscopic characters are here described in detail, and the microscopic characters were conclusively determined by common and polarized light microscopy. Results showed that these three T/PCMM can be easily identified by the present method even when powdered and combined. Thus, the microscopic method is applicable for authentication of the earlier three T/PCMM, and the morphological and microscopic characteristics described here are proposed as parameters to establish the authenticity of these three T/PCMM.

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.
