Role of the phloem in the biochemistry and ecophysiology of benzylisoquinoline alkaloid metabolism

Frontiers in Plant Science, 2013
Benzylisoquinoline alkaloids (BIAs) are a diverse group of biologically active specialized metabolites produced mainly in four plant families. BIA metabolism is likely of monophyletic origin and involves multiple enzymes yielding structurally diverse ...

Benzylisoquinoline alkaloid biosynthesis in opium poppy [PDF]

Planta, 2014
Opium poppy (Papaver somniferum) is one of the world's oldest medicinal plants and remains the only commercial source for the narcotic analgesics morphine, codeine and semi-synthetic derivatives such as oxycodone and naltrexone. The plant also produces several other benzylisoquinoline alkaloids with potent pharmacological properties including the ...

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.

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.

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 429-452, March/April 2026.
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...
