Reticuline
Reticuline is a chemical compound found in a variety of plants including Lindera aggregata,[1] Annona squamosa,[2] and Ocotea fasciculata (also known as Ocotea duckei).[3] It is based on the benzylisoquinoline structure.

Reticuline is one of the alkaloids found in opium, and experiments in rodents suggest it possesses potent central nervous system depressing effects.[3] It is the precursor of morphine and many other alkaloids.It is also toxic to dopaminergic neurons causing a form of atypical parkinsonism known as Guadeloupean Parkinsonism.[4]
Metabolism
3'-hydroxy-N-methyl-(S)-coclaurine 4'-O-methyltransferase uses S-adenosyl methionine and 3'-hydroxy-N-methyl-(S)-coclaurine to produce S-adenosylhomocysteine and (S)-reticuline.
Reticuline oxidase uses (S)-reticuline and O2 to produce (S)-scoulerine and H2O2.
Salutaridine synthase uses (R)-reticuline, NADPH, H+, and O2 to produce salutaridine, NADP+, and H2O. Salutaridine can then be transformed progressively to thebaine, oripavine, and morphine.
1,2-dehydroreticulinium reductase (NADPH) uses (R)-reticuline and NADP+ to produce 1,2-dehydroreticulinium, NADPH, and H+.
