Which poppies contain the most opium

Poppy seeds from a portion of the 1 seeds were homogenized using a spice blender and approximately mg of the seeds were weighed into glass Durham tubes four tubes for each of the solvents. For each solvent, the pH was altered to produce a solution of poppy seeds and solvent 1 mL at the specified pHs. To each solution, deuterated internal standard morphine-d 3 was added. The tubes were then capped and placed into an ultrasonic bath for 10 min, centrifuged at 4, rpm for 10 min.

Calibration solutions were prepared in the mobile phase on the day of analysis for each of the extractions. The ingredients were mixed into a batter and added to each of the dimples of mini-muffin trays purchased from Lakeland Ambleside, Cumbria.

The final weight of poppy seeds in each mini-muffin was approximately 1. They were then left to cool to room temperature. The poppy seed muffins were immersed in liquid nitrogen, crushed using a mortar and pestle and transferred to a spice blender for homogenisation prior to extraction and analysis by LC-MS.

The liquid nitrogen method was found to be easiest to apply to the muffins: this was due to the fact that the poppy seeds were incorporated into the sponge of the muffin. Trying to extract each poppy seed from the matrix proved very time consuming and was also considered that any alkaloids that may have interacted with the muffin matrix may also be included in results. Less fatty emulsion was also formed during the extraction method, when liquid nitrogen was employed.

A comparative study was carried out to establish if there was a difference between alkaloid levels resulting from poppy seeds incorporated into the matrix of the muffin to those resulting from poppy seeds coated onto a bread roll. The dough was then split into 4 equal portions and each one was pressed into poppy seeds.

The rolls were left to cool to room temperature and the poppy seeds were scraped from the surface using a metal spatula and homogenized in a spice blender prior to extraction and analysis by LC-MS. It was found that at the extremes of the polarity scale diethyl ether, dichloromethane, and water , the chromatograms produced were complex and with poor peak shape for the alkaloids; these observations were independent of pH.

In contrast, the optimum result, in terms of alkaloid presence and peak shape, was obtained using the solvent mixture i. For this reason, this extraction solvent mixture was used for all subsequent extraction's. For each source, the mean weight of each of the alkaloids in poppy seeds was calculated. When the levels of morphine in poppy seeds from each of the different sources was compared Table 7 , it was found that there was much variation within batch but also between sources of poppy seeds.

There is much variation in the extracted opiate compounds, which is primarily due to the environmental differences of the seeds Katrine et al. The country of origin for both of these poppy seed sources is unknown.

When the same comparison was carried out for codeine Table 7 it was also found that there was much variation within different portions of the same batch and between sources of poppy seeds as was the case with morphine. Source 2, which was found to have a level of morphine much higher than the other sources, was also found to have a higher level of codeine. No other similarities can be drawn from the data. It was also found that the same source with the highest levels of morphine and codeine also exhibited the highest levels of thebaine.

Noscapine was identified in only two of the eight sources of poppy seeds Table 7. It was found that the seeds from source 7 contained the highest levels of noscapine of the two sources where noscapine was identified. Papaverine was detected in some of the analyzed seeds but peaks were so small that it was not possible to quantify them. It has been identified that sub-varieties of Papaver somniferum L. However, this taxonomic information was not available from the suppliers of the seeds.

It has been known since Annett, that factors, such as the season in which the plants are grown, weather conditions, and quality and type of fertilizer used can greatly affect the levels of alkaloids biosynthesised by Papaver somniferum L. In turn, the levels of alkaloids found in opium latex will also be affected. No data currently exist that compares levels of alkaloids in opium latex and alkaloids from the same plant but it is assumed that the levels would correlate.

On this basis, the country of origin, where the plant was grown in the field e. This means that if a batch of poppy seeds is harvested from one field, naturally there will be variation in the levels of alkaloids from each of the plants.

It has also been shown that the alkaloids present in the opium latex may contaminate the poppy seeds as part of the growing process and that a batch of poppy seeds is the combination of multiple fields in one country: all of these factors may explain why there is such variation within batch and between sources of poppy seeds.

However, the muffin matrix greatly interfered with the extraction process. During the extraction process, a fatty emulsion was formed which affected further sample preparation techniques Figure 3.

These aliquots were filtered twice prior to being transferred into HPLC vials however when the chromatograms were analyzed for these muffin extractions, no alkaloids were identified. For this reason, it was not possible to include the poppy seed muffins extract results in the comparison between harvested poppy seeds, thermally processed seeds on their own and poppy seeds on the top of bread buns.

In addition, seed portions from three randomly selected sources were extracted and analyzed with the results shown in Table 8. Again, as was established with extractions of harvested poppy seeds there was much variation in the alkaloids identified and in the levels of those alkaloids present, Deuterated morphine was added prior to extraction of the alkaloids from the seeds and percentage extractions were incorporated into the calculations.

Figure 3. Sample tubes containing poppy seed muffin and extraction solvent, post agitation, and centrifugation. Table 8. Comparison of levels of alkaloids identified in harvested poppy seeds, seeds from the surface of bread rolls and seeds heated with no matrix. What was identified from this data was that whether the seeds were heated on the surface of the bread roll or were heated with no bread matrix, the levels of alkaloids if detected were considerably lower than in the harvested seeds.

Koleva et al. When comparing the results from the current work to levels published in the literature Table 9 it can be seen that these findings are in-keeping with those published by Sproll et al.

The work published by Grove et al. However, this could have been due to the sensitivity of the GC-MS instrument employed, the lack of information regarding the presence of other alkaloids present in poppy seeds at this time as the work reported by Grove et al.

The levels of alkaloids identified in the current work are generally lower than those found by Sproll et al. This research has shown that alkaloid variation exists depends on the specific alkaloids, their source and thermal processing.

It was clear from the data obtained in this current work, and from other studies published in the literature, that there is much variation in the levels of alkaloids identified in poppy seeds. This variation can be attributed to a variety of natural parameters, such as weather and soil conditions, but also in the way that the seeds are harvested Lachenmeier et al.

Processing methods prior to packaging and even the baking process has been shown to greatly affect the level of alkaloids Sproll et al. The findings of this study correlate with the studies published in the literature. When poppy seeds are consumed on a bun or roll, it has been estimated that each roll contains 1—4 g of poppy seeds Lachenmeier et al. The chromosome numbers of various species were counted. Further, for varieties or strains of P. The content of "porphyroxine-meconidine ", a red-turning alkaloid when heated in diluted mineral acid, of Japanese opium and of opium from successive lancings of P.

Examination of poppy varieties of Papaver somniferum L. It is a pleasure to acknowledge our indebtedness to Dr. Charles G. We wish to express our thanks to S. Mizumachi and Y. Shiuchi, National Hygienic Laboratory, for their assistance in making many of the analyses during this investigation.

Thanks are also due to T. Ohno, Kasukabe Experiment Station, for his aid in cytogenetical studies. The presence of morphine in Papaver setigerum DC. Morphine was detected in the pod, bud, and leafy parts of this poppy plant. For actual production of opium only P. No estimation of the alkaloids in opium from this poppy plant has been reported prior to the writing of the present paper.

The capsules of P. Besides our desire to clarify the legal point of its inclusion in the Opium Act, it was studied for scientific reasons and as a possible parent in hybridization.

This investigation was undertaken to grow and identify botanically P. With this in mind, the following two experiments, experiment I and experiment II, were made in successive years. The seeds were sown in October and The flowering continued almost throughout May of the following year. There were plants with violet flowers and also plants with mauve flowers in the strain. In experiment I both kinds were used without separating them, whereas in experiment II only plants with violet flowers were used.

Three or four incisiom, each covering a quarter of the capsule, were made at intervals of one day, till no more latex was yielded. The first incision began ten days after the petals had fallen. In experiment I it began at different dates in the sequence of flowering, irrespective of the strains, whereas in experiment II all sets of incisions made began on the same date.

Each incision consisted of four longitudinal slashes. The capsules were incised in the evening and the latex was gathered just after incision " Kiritori" collection and the following morning " Oigaki" collection.

The opiums thus obtained were mixed, as is the usual practice in collecting commercial opium from P. The presence of alkaloids, at the proper Rf values for morphine, codeine, and other opium alkaloids in the opium from P.

Opium was rubbed thoroughly with dilute hydrochloric acid, and the solution containing the alkaloidal salts was centrifuged. The supernatant solution was used for the paper chromatography. In the preparation of the solvent, the constituents were mixed, the mixture allowed to stand for some time, and the top layer of the mixture used for chromatography.

The characteristic dark blue colouration of the morphine spot on a filter paper, when treated with potassium iodoplatinate solution, and occurring at the proper Rf value for morphine, near 0. The other alkaloidal spots were coloured violet. The Rf value of the codeine spot was 0. Thebaine, papaverine, and narcotine were inseparable from each other by this solvent. Opium tincture was used for comparison to fix the position of the morphine spot more precisely under the particular conditions.
