This alkaloid is biosynthetically related to salutaridine, oripavine, morphine and reticuline. [6] In 2012 there was an amounted 146,000 kilograms of thebaine produced. [7] In 2013, Australia was the main producer of poppy straw rich in thebaine, followed by Spain and then France. By 2017, worldwide thebaine production dropped to 2,008 kg. [8]
Carbonate derivatives of 14β-hydroxycodeine "viz., 14β-hydroxy-6-O-(methoxycarbonyl)codeine, 6-O-methoxycarbonyl-14β-(methoxycarbonyloxy)codeine, and 14β-acetoxy-6-O-methoxy-carbonylcodeine, potential substrates for ring C modification in morphinane (sic) alkaloids, were synthesized for the first time."

Morphine. Synthesis of morphine-like alkaloids in chemistry describes the total synthesis of the natural morphinan class of alkaloids that includes codeine, morphine, oripavine, and thebaine and the closely related semisynthetic analogs methorphan, buprenorphine, hydromorphone, hydrocodone, isocodeine, naltrexone, nalbuphine, oxymorphone, oxycodone, and naloxone.
Pantopon, also known as Opium Alkaloids Hydrochlorides, is a preparation of opiates made up of all of the alkaloids present in opium in their natural proportions as hydrochlorides salts. [ 1 ] [ 2 ] [ 3 ] It can sometimes be tolerated by people who are allergic to morphine .
Opium poppy contains at least 50 different alkaloids, but most of them are of very low concentration. Morphine is the principal alkaloid in raw opium and constitutes roughly 8–19% of opium by dry weight (depending on growing conditions). [84] Some purpose-developed strains of poppy now produce opium that is up to 26% morphine by weight.
The compound is an alkaloid belonging to nymphaea caerulea, or blue lotus, but is also historically known as a morphine decomposition product made by boiling morphine with concentrated acid, hence the -morphine suffix. Contrary to its name, apomorphine does not actually contain morphine or its skeleton, nor does it bind to opioid receptors.
The terms 'opioid' and 'opiate' are sometimes used interchangeably, but the term 'opioid' is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain. [4] Opiates are alkaloid compounds naturally found in the opium poppy plant Papaver somniferum. [5] [6]
Medical use of alkaloid-containing plants has a long history, and, thus, when the first alkaloids were isolated in the 19th century, they immediately found application in clinical practice. [206] Many alkaloids are still used in medicine, usually in the form of salts widely used including the following: [ 14 ] [ 207 ]
