The alkaloids of Papaver somniferum L.—VII
Phytochemistry, 1964Abstract L -tyrosine-U- 14 C in solution was fed to the phloem region of the pedicels of poppy plants and the latex from the corresponding capsules was sampled at various intervals afterwards. Analyses of the samples confirmed the results previously reported on the rapid turnover of the alkaloids and the periodic disappearance of morphine ...

Genetics of Alkaloids inPapaver somniferum
Planta Medica, 1991Based on numerical and graphic analyses of 6 x 6 diallele cross progenies (n (2) = 36) over two environments, dominance was found to be most prevalent (in overdominance range without being inflated by non-allelic interactions) in parents for latex yield, and morphine, codeine, thebaine, and narcotine contents.

Papaver somniferum L. Papaveraceae
2020The plant is commercially cultivated in many parts of the world, chiefly in India, Afghanistan, China, Egypt, Asian part of Turkey, Iran, southeastern Europe, Nepal and Myanmar. Opium poppy and opium have been used since time immemorial. The milky exudate or latex was named opion by the ancient Greeks, derived from opos meaning sap or juice, which ...

QUANTIFICATION OF ESSENTIAL ELEMENTS IN PAPAVER RHOEAS L. AND PAPAVER SOMNIFERUM
Book of Proceedings: 1st International Conference on Chemo and BioInformatics, 2021Plants are very important for proper human nutrition, so the content of essential elements was investigated in two poppy species. Essential elements such as Ca, Na, K, Mg, Fe, Cu, Co, Mn, Mo and Zn play a vital role in various biological processes. Samples of roots, stems, leaves and seeds of Papaver rhoeas L. and Papaver somniferum were acid dissolved

Opium Poppy (Papaver somniferum)
2014Opium poppy which is an indispensible source of opium (dried exudate of fresh fruits of opium poppy after lancing) and poppy seeds is a cultivated species of Papaver somniferum. Due to narcotic properties of morphine, the major alkaloid in opium, Opium poppy cultivation is controlled by the States where it is cultivated and the UN worldwide.

Phosphatases in the latex of Papaver somniferum
Phytochemistry, 1975Abstract Phosphomonoesterases have been isolated from P. somniferum latex which show variability in their response to heavy metal ions and EDTA which are pH dependent, thus suggesting the presence of a group of enzymes. Acid phosphatase was found to be concentrated in the latex 25 000 g fraction.

Alkaloid formation of Papaver somniferum in Finland
Annales Botanici Fennici, 1984 Contents of morphine, codeine, thebaine, noscapine and papaverine were investigated by high performance liquid chromatography in six UNL strains of Papaver somniferum grown in harch climatic conditions in different parts of Finland. P.

Biosynthesis of Unnatural Papaverine Derivatives in Papaver somniferum
Journal of Natural Products, 1980The unnatural thebaine analog, oripavine 3-ethyl ether, was efficiently metabolized to morphine 3-ethyl ether and morphine in the opium poppy. An attempt to detect oripavine hy an isotope dilution experiment based on its presumed biosynthesis from reticuline was unsuccessful.

Biosynthesis of unnatural morphine derivatives in Papaver somniferum
Journal of the Chemical Society, Perkin Transactions 1, 1972Demethylation of various codeine derivatives to give the corresponding, unnatural derivatives of morphine has been studied in Papaver somniferum. The efficiencies of the unnatural processes have been compared with that of the natural, codeine into morphine, conversion by feeding mixtures of [2-3H]-labelled codeine derivatives with [N-methyl-14C]codeine.
