Abstract
It is a new approach to identify legal or illegal use of morphine through information on municipal wastewater. However, the sources of morphine in wastewater are complex, and distinguishing the contribution of different sources has become a key issue. A total of 262 influent samples from 61 representative wastewater treatment plants in a typical city were collected from October 2022 to March 2023. The concentrations of morphine, codeine, thebaine, papaverine, noscapine, and monoacetylmorphine were analyzed in wastewater and poppy straws. Combined with the proportion of alkaloids in poppy straws, the source analysis of alkaloids in wastewater was analyzed using the ratio method and positive matrix factorization model (PMF). Only five alkaloids were detected in wastewater, and monoacetylmorphine, a metabolite of heroin, was not detected. The concentrations of morphine and codeine were significantly higher than those of noscapine, papaverine, and thebaine. By constructing the ratios of codeine/(morphine + codeine) and noscapine/(noscapine + codeine), the source of poppy straw could be qualitatively distinguished. The PMF results showed that three sources of morphine for medical use, poppy straw, and codeine contributed 44.9%, 43.7%, and 9.4%, respectively. The different sources varied in these months due to the COVID-19 and influenza A outbreaks, in which the use of drugs containing poppy straws and codeine was the main source, whereas the use of morphine analgesics remained relatively stable. Inventory analysis further demonstrated the reliability of the source contributions from the PMF model, and morphine was not abused in this city.

Abstract
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.

Abstract
INTRODUCTION Thebaine is an alkaloid in poppy seeds that is neurotoxic to animals. Data on its clinical effects and toxicokinetics in people are minimal. In 2022, poppy seeds high in thebaine entered the Australian food market, and people consuming tea made from these poppy seeds developed poisoning. METHODS Three patients who drank poppy seed tea and developed neuromuscular toxicity consented for thebaine to be quantitated in serial blood samples. Blood samples were analyzed by liquid chromatography with high-resolution mass spectrometry. RESULTS Case 1: A man in his 60s presented with drowsiness, vomiting, malaise and myoclonus. He developed metabolic acidosis with hyperlactataemia, acute kidney injury requiring haemodialysis, convulsions, rhabdomyolysis, and was in the hospital for 18 days. The admission thebaine blood concentration was 2.1 mg/L, and the apparent elimination half-life was 14.8 h. Case 2: A man in his 30s presented with myoclonus, rigidity, vomiting, and dizziness. He developed metabolic acidosis with hyperlactataemia, acute kidney injury, and myalgias. The admission thebaine blood concentration was 4.1 mg/L, and the apparent elimination half-life was 11.6 h. Case 3: A man in his 30s presented with myoclonus, rigidity, clonus, diaphoresis, and abdominal pain. The admission thebaine blood concentration was 2.2 mg/L, and the apparent elimination half-life was 8.3 h. DISCUSSION Neuromuscular toxicity, metabolic acidosis with hyperlactataemia, acute kidney injury, and gastrointestinal symptoms were prominent clinical features in these patients after drinking poppy seed tea. Effects persisted for days, and all survived, despite thebaine concentrations far exceeding those in published forensic reports, although human data are sparse. Compared to rats, the thebaine apparent elimination half-life is much longer in humans who develop symptoms at lower concentrations. CONCLUSIONS Despite relatively high thebaine blood concentrations and moderate to severe poisoning, outcomes were favourable with early presentations. It is possible that acute kidney injury prolongs the apparent elimination half-life of thebaine.

Abstract
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.

Abstract
In May 2011, numerous poppy plants closely resembling Papaver bracteatum Lindl., a type of narcotic plant that is illegal in Japan, were distributed directly from several large flower shops or through online shopping throughout Japan, including the Tokyo Metropolitan area. In order to better identify the narcotic plants, the relative nuclear DNA content at the vegetative stage was measured by flow cytometric (FCM) analysis in 3 closely-related species of the genus Papaver section Oxytona, namely P. orientale, P. pseudo-orientale, and P. bracteatum, based on the difference between the chromosome numbers of these species. The results showed that the nuclear DNA content differed between these 3 species, and that most of the commercially distributed plants examined in this study could be identified as P. bracteatum. The remaining plants were P. pseudo-orientale, a non-narcotic plant. In addition, the FCM results for the identification of P. bracteatum completely agreed with the results obtained by the morphological analysis, the inter-genic spacer sequence of rpl16-rpl14 (PS-ID sequence) of chloroplast DNA, and the presence of thebaine. These results clearly indicate the usefulness of FCM analysis for the identification of P. bracteatum plants, including when they are in their vegetative stage.

Abstract
In this paper, we report a case of misidentification of medicinal plants involving dried petals of Papaver rhoeas (red poppy) contaminated with Papaver bracteatum (scarlet poppy) petals. Preliminary TLC analysis indicated the presence of thebaine either in the fluid extracts or in the petals. It was therefore necessary to carry out an accurate botanic examination of the plant material, which revealed contamination of the red poppy petals with scarlet poppy petals. Moreover, to confirm the adulteration, we developed and validated an efficient, reversed-phase ion pair HPLC method for determination of the alkaloids specific for the Papaver species. Six petal batches and five commercial fluid extracts were analyzed. Only one petal batch from Iran contained thebaine and its analogue oripavine while the alkaloids typical for the Papaver bracteatum species were identified in all fluid extracts, meaning that they were all prepared with contaminated petals.

Abstract
In this work, a batch chemiluminescence (CL) method has been proposed for the simultaneous determination of two structurally similar alkaloids, noscapine and thebaine. The method is based on the kinetic distinction of the CL reactions of noscapine and thebaine with Ru(bipy)(3)(2+) and Ce(IV) system in a sulfuric acid medium. The least squared support vector machine (LS-SVM) regression was applied for relating the concentrations of both compounds to their CL profiles. The parameters of the model consisting of sigma(2) and gamma were optimized by constructing LS-SVM models with all possible combinations of these two parameters to select the model with the minimum root mean squared error of cross validation (RMSECV) as the best. The parameters of this model were then selected as optimized values. Under the optimized experimental conditions for both compounds, the detection limits obtained using the LS-SVM regression were 0.08 and 0.1 micromo lL(-1) for noscapine and thebaine, respectively. The proposed method was utilized for the simultaneous determination of the compounds in pharmaceutical formulations and plasma samples with satisfactory results.

Abstract
This paper describes the determination of opiate alkaloids (morphine, codeine, oripavine and thebaine) in industrial process liquors using capillary zone electrophoresis with UV-absorption detection at 214 nm. A study of cyclodextrin type and concentration revealed that the addition of 30 mM hydroxypropyl-beta-cyclodextrin to the electrolyte solution (100mM Tris adjusted to pH 2.8) was suitable to resolve the four analytes of interest. Typical analysis time was 12 min and the limit of detection for each alkaloid was 2.5 x 10(-6) M. The results for the proposed methodology were in good agreement with those of a conventional HPLC procedure. Under the same conditions, short-end injection was used to reduce the effective separation length from 41.5 to 8.5 cm, which allowed the determination of morphine and thebaine in process liquors within 2.5 min.

Abstract
Opiates are some of the most widely prescribed drugs in America and are often abused. Demonstrating the presence or absence of opiate compounds in postmortem fluids and/or tissues derived from fatal civil aviation accidents can have serious legal consequences and may help determine the cause of impairment and/or death. However, the consumption of poppy seed products can result in a positive opiate drug test. We have developed a simple method for the simultaneous determination of eight opiate compounds from one extraction. These compounds are hydrocodone, dihydrocodeine, codeine, oxycodone, hydromorphone, 6-monoacetylmorphine, morphine, and thebaine. The inclusion of thebaine is notable as it is an indicator of poppy seed consumption and may help explain morphine/codeine positives in cases where no opiate use was indicated. This method incorporates a Zymark RapidTracetrade mark automated solid-phase extraction system, gas chromatography/mass spectrometry, and trimethyl silane (TMS) and oxime-TMS derivatives. The limits of detection ranged from 0.78 to 12.5 ng/mL. The linear dynamic range for most analytes was 6.25-1600 ng/mL. The extraction efficiencies ranged from 70 to 103%. We applied this method to eight separate aviation fatalities where opiate compounds had previously been detected.

Abstract
The effect of fertilizer on the yield and yield components of opium from Papaver somniferum L.cv.Ikkanshu were investigated from 1993 to 1995. The weight of opium per one capsule was tendency to increase in the order of peat moss > pulverized charcoal > compound fertilizer, but the differences among the results were not significant. Furthermore, no difference in the capsule weight per 100 m2 and the yields of opium and alkaloids per 100 m2 were detected. The significant difference was only observed when the data were compared among the weights and yields of different years. The difference among the yield of opium was mainly due to the weight of opium per one capsule. The weight of opium per one capsule showed a high correlation with capsule husk weight. The alkaloids contents in opium obtained with a different fertilizer application showed no difference. Morphine content at the first lancing was about 11%, and the value decreased with the order of lancing. On the contrary, the codeine and the thebaine content did not change during lancing and the value were 6-7% and 3%, respectively. The papaverine and the noscapine content decreased in the order of lancing.

Abstract
A simple and robust capillary electrophoresis chemiluminescence detection system for the determination of morphine, oripavine and pseudomorphine is described, based upon the reaction of these analytes with acidic potassium permanganate in the presence of sodium polyphosphate. The reagent solution was contained in a quartz detection cell which also held both the capillary and the anode. The resultant chemiluminescence was monitored directly using a photomultiplier tube mounted flush against the base of the detection cell. To ensure that no migration of the permanganate anion occurred, the anode was placed at the detector end whilst the electroosmotic flow was reversed by the addition of hexadimethrine bromide (0.001% m/v) to the electrolyte. The three analytes were separated counter to the electroosmotic flow via their interaction with alpha-cyclodextrin. The methodology realised detection limits (3 x S/N) of 2.5 x 10(-7) M for both morphine and oripavine and 5 x 10(-7) M for pseudomorphine. The relative standard deviations of the migration times and the peak heights for the three analytes ranged from 0.6 up to 0.8% and from 1.5 up to 2.1%, respectively.

Abstract
A method for the simultaneous determination of codeine, morphine, thebaine, papaverine and narcotine in pericarpium papaveris by gas chromatography with wide bore capillary column is described. The major components in pericarpium papaveris were extracted with methanol and chloroform by supersonic extraction and evaporation. The residue was dissolved in methanol. The resulting solution was used for analysis. The conditions for determination were: FID detector, HP-1 capillary column, 5 m x 0.53 mm x 2.65 microns film, column temperature 260 degrees C, The method requires 10 minutes for the whole analysis. The average recoveries of codeine, morphine, thebaine, papaverine and narcotine in the sample were 94.0%, 96.5%, 93.8%, 91.0% and 91.4% respectively. The relative standard deviations were from 0.92% to 2.75%. The advantages of this method are simple, rapid, accurate and sensitive.

Abstract
Papaver bracteatum is an important source of opiates because of its high thebaine content. An efficient and convenient method of determining thebaine, not only in the root, but in the more highly pigmented capsule, stem and leaf, is urgently required. We decided to examine these in detail on a wide variety of plant material and to choose an assay method which is convenient and gives reproducible results. A simple method for the quantitative extraction and analysis of thebaine in the different tissues (capsule, root, leaf and stem) of papaver bracteatum has been established. The powdered materials were extracted with methanol under ultrasonic condition. The procedure of extraction is simple, rapid and reliable. The assay method gave satisfactory reproducibility for a wide range of plant materials (coefficient of variation 2.9% to 5.4%). The linear range of response of thebaine was from 5.0 to 500.0 mg/L. The minimum limit of detection was 2 ng. The operating time of the assay is about 20 min. The presence of other alkaloids did not interfere with the assay reported here in.

Abstract
The universally accepted 300 ng/ml cut-off limit for opiate assays stated to be mandatory for all drug screening laboratories by the Substance Abuse and Mental Health Services Administration, has been questioned recently due to positive results being obtained following the ingestion of poppy seed containing food products. To establish the plausibility of the 'the poppy seed defence' the concentrations of codeine, norcodeine, morphine, normorphine and thebaine (a potential marker for seed ingestion) in several varieties of poppy seeds from different countries were quantified by GC-MS. The country of origin of the seed specimen analysed and the preparation of the seeds prior to their culinary use was found to influence the alkaloid concentration determined. The maximum morphine and codeine concentrations determined in the seeds were found to be 33.2 and 13.7 micrograms/g seed respectively. In addition, thebaine concentrations were found to vary with each seed sample analysed. Following the consumption of bread rolls (mean 0.76 g seed covering per roll) by four subjects, all urine specimens analysed produced negative results (using the Dade Bebring EMIT II opiate screening assay) with the exception of one subject (body weight 63.0 kg) who consumed two poppy seed rolls. In this subject opiate positive screening results were obtained for up to 6 h post ingestion with maximum urinary morphine and codeine concentrations of 832.0 ng/ml (@ 2-4 h post ingestion) and 47.9 ng/ml (@ 0-2 h post ingestion) respectively being achieved. Following the ingestion of poppy seed cake containing an average of 4.69 g of seed per slice by four individuals, opiate positive screening results were obtained for up to 24 h. In one subject (dose equivalent to 0.07 g poppy seed/kg body weight) maximum urinary morphine and codeine concentrations of 302.1 ng/ml (@ 0-2 h) and 83.8 ng/ml (@ 2-4 h) respectively were recorded. The elimination of thebaine was found to vary widely between individuals, therefore suggesting that its absence from a specimen is not necessarily indicative of opiate abuse. These findings demonstrate that the poppy seed defence could be used as an argument in medico-legal and employment medical cases. Great care should therefore be taken when interpreting the data produced when screening for opiates.

Abstract
In addition to codeine and morphine, three more compounds: narcotine (noscapine), papaverine, and thebaine were found in Indian and Netherlands poppy seeds (Papaver somniferum L). The compounds were detected by a GC/MS technique and the identities were confirmed by comparing retention times and ion ratios with the known references. The concentrations of codeine, morphine, thebaine, papaverine, and narcotine were 44, 167, 41, 67, and 230 micrograms/g in Indian poppy seeds, and were 1.8, 39, 1.0, 0.17, 0.84 micrograms/g in Netherlands poppy seeds, respectively. Because these compounds may be urinary products after poppy seed consumption, the lowest detectable concentrations of codeine, morphine, thebaine, papaverine, and narcotine in urine are of interest and were found to be 4, 4, 5, 0.4, and 4 ng/ml, respectively. The detection of urinary narcotine, papaverine, or thebaine may be utilized to differentiate poppy seed consumption from illicit codeine, morphine, or heroin use.

Abstract
Opium alkaloids (thebaine, codeine and morphine) have been conjugated with bovine serum albumin (BSA) to give individual antigen conjugates which are analyzed by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry. It became clear that 9 molecules of thebaine were contained in a thebaine-BSA conjugate. Codeine and morphine contents in individual conjugates were determined to be 12 and 6 molecules, respectively.

Abstract
The convulsant opiate thebaine, an intermediate of morphine biosynthesis, was purified from bovine brain to homogeneity by gel filtration and high-performance liquid chromatography (HPLC) monitored by a radioimmunoassay. The immunoreactive material behaved identically to standard thebaine in two HPLC systems and was confirmed to be thebaine by combined gas chromatography/mass spectrometry. To our knowledge, the presence of thebaine in mammalian tissue has not been demonstrated previously. Codeine and morphine were also found to exist in ovine brain. The presence of thebaine in ovine brain provides strong evidence that morphine and codeine, in various mammalian tissues, are of endogenous origin and actually biosynthesized from a precursor.

Abstract
In this study, poppy seeds were examined for a natural constituent that might serve as a maker for the seeds' ingestion as opposed to opiate abuse. Thebaine was selected as possible marker, since it was found to be a component of all poppy seeds examined and was not a natural component of different heroin samples. During the course of this investigation, a new extraction and cleanup procedure was developed for the gas chromatographic/nitrogen phosphorus detection (GC/NPD) and gas chromatographic/mass spectrometric (GC/MS) analysis of morphine and codeine in urine. A linear response, over a concentration range of 25 to 600 ng/mL, was obtained for codeine and morphine (r = 0.9982 and 0.9947, respectively). The minimum detectable level (LOD) and limit of quantitation (LOQ) for morphine were 10 and 30 ng/mL, respectively; whereas LOD and LOQ for codeine were 2 and 8 ng/mL, respectively. The coefficients of variance (CV, n = 6) for morphine and codeine analyses at the 100-ng/mL level were 13.3 and 4.6%, respectively. This procedure was used for the analysis of urine samples from five poppy seed eaters who each ingested 200 g of poppy seed cake. Results indicated that significant amounts of morphine and codeine are excreted in urine and that in all subjects, at least at one point in time, the apparent morphine concentration as determined by radioimmunoassay (RIA) analysis exceeded the cutoff value (300 ng/mL) established for screening. Thebaine was not detected in urine specimens collected following poppy seeds ingestion and thus could not be used as a marker.

Abstract
A rapid colorimetric test for the determination of thebaine in dried, extracted Papaver bracteatum is described. The method is based on the development of an orange color formed by the nitroso color reaction for phenols. The absorption peak is near 450 nm. The linear range response is from 0 to 1.0 mg of thebaine. The reproducibility of the method is quite good, making it useful for process evaluation and in a selection program for the cultivation of P. bracteatum for optimum thebaine content.

Abstract
A high pressure liquid chromatographic isocratic procedure is described for determining and quantitating the 5 major alkaloids narcotine, papaverine, thebaine, codeine, and morphine in Papaver somniferum L. and thebaine in Papaver bracteatum Lindl. Other papaveraceous alkaloids, including salutaridine, oripavine, laudanosine, isothebaine, cryptopine, alpinigenine, narceine, protopine, and gnoscopine, were also quantitated. The values for morphine, codeine, and thebaine in P. somniferum were in agreement within 5--9% with values obtained by the United Nations Narcotics Laboratory by other methods. In contrast to previously reported procedures, the advantage of this method is that no precolumn or other purification other than solvent extraction of the capsular tissue is necessary. Isocratic chromatography alone on a single column resolved the 5 major alkaloids.

Abstract
An interlaboratory procedure for the quantitative extraction and analysis of thebaine from different tissues of Papaver bracteatum Lindl. is presented. Each step was evalutated for the yield of thebaine by use of 1-3H-thebaine and GLC. The method of drying and milling of tissue and the size of resultant particles were important factors in the quantitative recovery of thebaine.

Abstract
A simple spectrophotometric determination of thebaine based on the complexation reaction with bromcresol green was developed. The yellow complex was extracted with chloroform over the pH 1.5--4.5 range. The solution of the complex in chloroform showed the maximum absorption at 415 nm and obeyed Beer's law over the concentration range of 4.0--14.0 microgram/ml. The molar absorptivity of the complex was 1.9460 X 10(4). The ratio of thebaine to bromcresol green in the complex was 1:1. The method was applied successfully to the direct determination of thebaine in the Arya II population capsules of Papaver bracteatum Lindl. The thebaine content of the dried capsules was 3.14%.

Abstract
Approximately 200 accessions of Papaver species were evaluated for identification as P. bracteatum Lindl. and for thebaine content. Fifteen authentic P. bracteatum accessions were selected on the basis of chromosome count. Statistical analyses of variation in alkaloid content were made for these accessions. Four of the 15 warranted further study based on the vigor of the plant and the total thebaine present in the tissue. Significant variability in thebaine content was found in wild strains of P. bracteatum, thus requiring genetic selection studies. The data showed that total yield potential of thebain should be considered in selecting P. bracteatum strains for commercial growth rather than concentrating on strains that produce the highest thebaine concentrations. A method for the quantitative estimation of thebaine from P. bracteatum is presented.

Abstract
A method is described for the quantitative analysis of thebaine from Papaver bracteatum, using a single high-pressure liquid chromatographic column. The procedure gives base-line separation of thebaine without the need for gradient elution equipment, and can be completed within 12 min. Thebaine isolated by this technique was shown to be pure, regardless of the age of plant or plant part from which it was obtained.

Abstract
According to the alkaloid profiles, five different chemotypes (A, B, C, D, and E) were classified in Papaver orientale L. with haploid chromosome number n = 14. Chemotype A had only oripavine; chemotype B contained oripavine and thebaine; chemotype C had isothebaine in addition to oripavine; chemotype D contained oripavine and alpinigenine; and chemotype E had oripavine, thebaine, and alpinigenine. In all chemotypes, oripavine was either the sole alkaloid or the single major alkaloid.

Abstract
Plants of Papaver bracteatum Lindl. derived from different germplasm sources within one Iranian collection were grown for 18 and 37 weeks in the greenhouse and controlled environment chambers. Gas-chromatographic analyses showed significant differences between thebaine concentrations of root tissue for 18-week-old plants, but not for 37-week-old plants. The two age groups did not differ in thebaine yield per unit of dry weight of root tissue. However, due to more profuse root growth, the total yield of thebaine from roots of the older plants was about four times that of the younger plants. Shoot thebaine concentrations differed significantly for 18- and 37-week-old plants. The over-all mean thebaine concentration for shoots of older plants was nearly twice that of younger plants. The variation in thebaine concentrations in these plants suggested genetic differences between the germplasm sources. Thus, domestication of P. bracteatum will require selection of germplasm from within and between collections, for plants of the greatest economic potential.

Abstract
Several solvents have been examined in the process of developing a convenient method for extracting powdered material and removing interfering pigments to produce an extract of Papaver bracteatum suitable for g.l.c. assay. The most suitable extracting solvent was aqueous acetic acid (5%); the assay method gave satisfactory reproducibility with a wide range of plant materials (coefficient of variation 0.63 to 3.33%). The accuracy was checked by recovery experiments with pure thebaine and by examination of exhausted marcs. The presence of other alkaloids did not interfer with the assay. There were substantial differences in the amounts of thebaine extracted from capsule and root samples by ammoniacal methanol and by aqueous acetic acid, indicating the presence of thebaine in a "bound" form. The minimum amount of thebaine that could readily be determined by the g.l.c. method was 0.3 mg in the sample of powder used for the assay.

Abstract
Abstract
Certain strains of P. bracteatum Lindl. are reported to contain in the roots significant quantities of thebaine, which can be used for the production of codeine and other opiates. Results from plants raised from Iranian seeds and grown near London for 4 to 5 years are presented. The botanical and chemical characters correspond closely to those of the active strain Halle III described by Böhm (1970) and enable this plant to be clearly distinguished from the closely related P. orientale L. The thebaine content of the roots was 0.25 % which is much lower than the value of 0.7 to 1.3% reported in Halle III roots. The fruiting tops, however, were also investigated and found to contain significant amounts of thebaine in field conditions. If tops were harvested in the summer and roots in the autumn, about 15 kg thebaine per hectare should be produced from our strain grown in the conditions described. This compares favourably with about 1 kg alkaloids per hectare from Turkish opium production or even the 3 kg per hectare from the high yielding Indian farms.
