HITTITE GALAKTAR “OPIUM (POPPY)”?
2023Galaktar is a noun that refers to a plant or substance mentioned in Hittite texts. In 1983, H. G. Güterbock conjectured that galaktar corresponds to the opium poppy (Papaver somniferum) although its presence in Hittite Anatolia was uncertain. However, some clues derived from Hittite texts together with some artefacts, suggest that Güterbock’s ...

Opium Poppy (Papaver somniferum)
2006The genetic transformation of opium poppy, Papaver somniferum, offers the opportunity to study the mechanisms involved in the regulation of benzylisoquinoline and morphinan alkaloid biosynthesis. The development of an efficient transformation protocol for opium poppy has allowed us to transform a range of genotypes from all around the world, including ...

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.

Trends in Plant Science, 2001
After seven years of research, scientists recently announced the world's first opium-free poppy. Scientists at the Central Institute of Medicinal and Aromatic Plants (CIMAP) developed the opiumless and alkaloid free poppy variety, Sujata. Occasionally breeders identify opiumless poppy plants, called bunjha, but their progeny have normal levels of opium.

Crop Science, 2001
Amplified restriction fragment length polymorphic (AFLP) DNA analysis was performed on leaf samples of 40 accessions of opium poppy (Papaver somniferum L.) and two other control genera (Papaver bracteatum Lindley and Papaver setigerum DC.) from a commercial breeding collection held in Tasmania, Australia.

Identification of the Opium Poppy
Journal of the Forensic Science Society, 1966A simple technique for the identification of the Opium Poppy is described. The principal alkaloids are extracted from the plant by boiling water and identified by thin-layer chromatography in a benzene, dioxane, ammonium hydroxide, ethanol solvent.

Evolution of morphine biosynthesis in opium poppy
Phytochemistry, 2009Benzylisoquinoline alkaloids (BIAs) are a group of nitrogen-containing plant secondary metabolites comprised of an estimated 2500 identified structures. In BIA metabolism, (S)-reticuline is a key branch-point intermediate that can be directed into several alkaloid subtypes with different structural skeleton configurations.

Secrets of the opium poppy revealed
Neuropharmacology, 2004Studies concerning drugs of abuse have made major contributions in defining the circuitry, as well as cellular and molecular substrates that underlie certain behaviors. Opiate drugs for example, have revealed important insights concerning pain perception and reward.

Glycoproteins of the opium poppy
Phytochemistry, 1980Abstract Two carbohydrate-protein fractions were isolated from the water-soluble biopolymer from opium poppy capsules by chromatography on SP-Sephadex. The carbohydrate chains are composed of arabinose, rhamnose, xylose, mannose, glucose, galactose, galacturonic acid, glucuronic acid and 4- O -methyl glucuronic acid.
