Opium alkaloids, biosynthesis, pharmacology and association with cancer occurrence [PDF]

Open Biology, 2023
Papaver somniferum L. (Family: Papaveraceae) is a species well known for its diverse alkaloids (100 different benzylisoquinoline alkaloids (BIAs)). L-tyrosine serves as a precursor of several specific metabolites like BIAs.

Opium Alkaloids in Harvested and Thermally Processed Poppy Seeds [PDF]

Frontiers in Chemistry, 2020
The opium alkaloids (morphine, codeine, thebaine, noscapine, and papaverine) have been detected on poppy seeds; they are widely used by the food industry for decoration and flavor but can introduce opium alkaloids into the food chain.
