Quantitative ¹H NMR metabolomics reveals extensive metabolic reprogramming of primary and secondary metabolism in elicitor-treated opium poppy cell cultures

BMC Plant Biology, 2008
Background Opium poppy (Papaver somniferum) produces a diverse array of bioactive benzylisoquinoline alkaloids and has emerged as a model system to study plant alkaloid metabolism.

Content of alkaloids in ornamental Papaver somniferum L. cultivars growing in Estonia; pp. 34–39 [PDF]

Proceedings of the Estonian Academy of Sciences, 2017
The alkaloid content in industrial opium poppies (Papaver somniferum L.) has been studied by numerous authors, but not in ornamental cultivars.The aim of the study was to investigate the content of morphine, codeine, and papaverine in P.

Opium Alkaloids

Bioactive Compounds in Nutraceutical and Functional Food for Good Human Health, 2020
Opium alkaloids, derived from crude Papaver somniferum L. plant, are potent analgesic drugs, but their use is limited because of dependence and withdrawal. Opium alkaloids activate the mesocorticolimbic dopaminergic system, which project from the ventral

Improving the food safety of bakery products by simultaneously monitoring the occurrence of pyrrolizidine, tropane and opium alkaloids.

Food Chemistry
The exponential number of food alerts about concerning levels of some plant-alkaloids, such as pyrrolizidine, tropane and opium alkaloids, have stressed the need to monitor their occurrence in foods to avoid toxic health effects derived from their intake.

Chemometric approach for development, optimization and validation of HILIC methods used for the determination of alkaloids from poppy straw

Macedonian Journal of Chemistry and Chemical Engineering, 2014
Two hydrophilic interaction liquid chromatography (HILIC) methods for simultaneous determination of the major alkaloids (morphine, codeine, thebaine, oripavine, papaverine and noscapine) in opium poppy straw (Papaver somniferum L., Papaveraceae) were ...

Evaluation the Variation of Morphine Percentage in Different Turkish Opium Poppy (Papaver somniferum L.) Lines in Three Years [PDF]

Journal of Medicinal Plants and By-products, 2015
Opium poppy (Papaver somniferum L.) has two major products: alkaloids in the capsules and the seeds. It is known that opium poppy today contains alkaloid in great quantities.

Investigating the effect of different grinding conditions and methods on the concentration of opium alkaloids in poppy seeds as a good reduction practice

Journal of Food Composition and Analysis
as a good practice for OAs reduction may be insufficient, as it seems to have minimal impact on other OAs with any of the tested methods and conditions.

A Scalable Large Language Model‐Aided Approach for Mining Plant‐Compound Pairs From Scientific Literature

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding plant chemicals is vital for medicine and agriculture, but global data remain fragmented and biased. We developed an AI‐powered tool to automatically extract plant‐compound information from scientific literature at scale and low cost. Our analysis revealed significant knowledge gaps, particularly in the Southern Hemisphere. By efficiently
