laudanosine/papaver somniferum

The berberine bridge enzyme cDNA bbe from Papaver somniferum L. was transformed in antisense orientation into seedling explants of the industrial elite line C048-6-14-64. In this way, 84 phenotypically normal To plants derived from embryogenic callus cultures were produced. The selfed progeny of

A high pressure liquid chromatographic isocratic procedure is described for determining and quantitating the 5 major alkaloids narcotine, papaverine, thebaine, codeine, and morphine in Papaver somniferum L. and thebaine in Papaver bracteatum Lindl. Other papaveraceous alkaloids, including

The opium poppy, Papaver somniferum, is one of mankind's oldest medicinal plants. Opium poppy today is the commercial source of the narcotic analgesics morphine and codeine. Along with these two morphinans, opium poppy produces approximately eighty alkaloids belonging to various

Laudanosine, reticuline, codamine, and laudanine are members of the tetrahydrobenzylisoquinoline family of natural products. These alkaloids are present in the opium poppy, Papaver somniferum, and are subsequently found as impurities in clandestinely processed morphine. Morphine is then synthesized

Noscapine is a benzylisoquinoline alkaloid produced in opium poppy (Papaver somniferum) and other members of the Papaveraceae. It has been used as a cough suppressant and more recently was shown to possess anticancer activity. However, the biosynthesis of noscapine in opium poppy has not been
