Poppy capsule

More interesting, as regards future developments, are the eiforts now being made to dispense with opium as an intermediate in the production of morphine. The early history of experiments in the direct extraction of the alkaloid from poppy capsules and poppy straw has been recounted by Goris and by Wiiest and Frey. ... [Pg.176]

UNODC has also started to conduct yield surveys in some countries, measuring the yield of test fields, and to develop methodologies to extrapolate the yields from proxy variables, such as the volume of poppy capsules or the number of plants per plot. This approach is used in South-East Asia as well as in Afghanistan. All of this is intended to improve yield estimates, aiming at information that is independent from farmers reports. The accuracy of the calculated yields depends on a number of factors, including the number of sites investigated. In the case of Afghanistan the confidence interval for the mean yield results in the 2006 survey was, for instance, +/- 3% of the mean value (tt= 0.1). [Pg.260]

Preparation By extraction of poppy capsules or opium (opium contains 9-14 % morphine depending on the source) with water, precipitation with aqueous Na2C03 solution, washing of the precipitate with ethanol and dissolution in dilute acetic acid (Horner et al. (Knoll), 1977, Trauner et al.,1983, Hudlicky et al.,1996). [Pg.203]

The content of narcotoline in poppy capsules (0.1-0.2%) is useful for preparative purposes (212, 221-224). In connection with this problem, colorimetric determination (223), paper chromatography (92, 94, 103, 107, 108, 112, 189), potentiometric determination (225), and thin-layer chromatography (161) were utilized. Indirect determination of narcotoline is possible via cotarnoline (149), especially polarographically (226, 227). The dissociation constant of narcotoline has been determined (228). [Pg.121]

Mix the poppy capsules with four pints of the water, and infuse for twenty-four hours, stirring them frequently then pack them in a percolator, and, adding more of the water, allow the liquor to pass slowly until about two gallons have been collected, or the poppies are exhausted. Evaporate the liquor by a water-bath until it is reduced to three pints. When quite cold, add the spirit, let the mixture stand for twelve hours, and filter. Distil off the spirit, evaporate the remaining liquor to two pints, and... [Pg.237]

Cell-free extracts of the whole plant were shown to be able to convert (/, 5)-reticuline to salutaridine 466). The enzymatic conversion of codeine to morphine in isolated poppy capsules was reported by Hsu et al. 467). In addition, cultures of cells in an embryogenic state were able to convert codeine to morphine at a low rate, although the major metabolic products of codeine were iV-oxides. (450). [Pg.84]

The earliest evidence for the deliberate use of poppies are the poppy seeds and poppy capsules, which have been found from archaeological unearthing of buildings on stilts, dating back to the early Stone Age (3000-2500 BC) in the shallow lakes of Switzerland (cantons Zurich, Thurgau, Bern). [69] Similar discoveries have been made in the provinces of Milan, Savoy and Provence. The poppy was presumably used as a spice in foodstuffs and for the preparation of vegetable oUs. [Pg.261]

Opium is a natural product obtained from unripe poppy capsules. There are over 100 species of the genus Papaver (or poppy) known, however only two, Papaver somniferum and Papaver setigerum D.C., are the main plants cultivated in the production of opium. [Pg.1708]

For these experiments to be successful, it is imperative that the labeled precursors be fed directly to the latex in the poppy capsules, otherwise the added labeled dopa fails to penetrate to the site of the appropriate aminotransferase... [Pg.48]

In modem medicine, mily the purified opium alkaloids and their derivatives are commonly employed. Although the ripe poppy capsule can contain up to 0.5 % total alkaloids, opium represents a much concentrated form and up to 25 % of its mass is composed of alkaloids. Of the many (>40) alkaloids identified, some six represent almost all of the total alkaloid content. Actual amounts vary widely, e.g., morphine (4-21 %), codeine (0.8-2.5 %), thebaine (0.5-2.0 %), papaverine (0.5-2.5 %), noscapine (narcotine) (4—8 %), and narceine (0.1-2 %). A t3q>ical commercial sample of opium would probably have a morphine content of about 12 %. Powdered opium is standardized to contain 10 % of anhydrous morphine, usually by dilution with an approved diluent, e.g., lactose or cocoa husk powder. The alkaloids are largely combined in salt form with meconic acid, opium containing some 3-5 % of this material. Meconic acid is invariably found in opium but, apart from its presence in other Papaver species, has not been detected elsewhere. It gives a deep red-colored complex with ferric chloride, and this has thus been used as a rapid and reasonably specific test for opium. Of the main opium alkaloids, only morphine and narceine display acidic properties, as well as the basic properties due to the tertiary amine. Narceine has a carboxylic acid function, while morphine is acidic due to its phenolic hydroxyl. This acidity can be exploited for the preferential extraction of these alkaloids (principally morphine) from an organic solvent by partitioning with aqueous base (Table 15.6). [Pg.434]

A number of experiments were performed with the opium poppy (Papaver somniferum). The highest alkaloid level in this species was noted when it was cultivated in moderately dry fields in the tropics. Il inskaya and Yosifova (1956) found that the percentage of total alkaloids in the poppy capsule increased in the plants the farther south they were grown. Voseu-... [Pg.91]

Evidence for the existence of the poppy in Anatolia during the time of the Hittite Empire, ca. 1400—1200 BC, is provided by two identical gold pins. These faithfully reproduce details of the poppy capsule and its stalk down to a loose object inside (presumably representing seeds) so that the pins can rattle hke the real thing (Merril-lees 1979). [Pg.3]
