Friedrich Sertürner — Morphine, the Opium Poppy and the First Alkaloid

Around 1804, in the back room of a pharmacy in north-west Germany, a young pharmacist’s assistant named Friedrich Wilhelm Sertürner (1783–1841) drew a white crystalline substance out of opium, the dried milky juice of the poppy. Over the next thirteen years he showed that this substance behaved like an alkali — it neutralised acids and formed salts — and that it carried opium’s power to bring sleep. In 1817 he named it morphium, after Morpheus, the Greek god of dreams. It was the first alkaloid, the first nitrogen-containing “plant base”, ever isolated, and historians of pharmacy count it as one of the moments when the old apothecary’s craft became a laboratory science.

This wing tells the story in four deep-dive articles: the man himself, the experiments of 1804–1817, the opium poppy and the chemistry of the molecule it makes, and the run of plant alkaloids and the long medical history of morphine that followed. The overview below gives the whole story on one page. It is history and pharmacology for curious readers; morphine is a powerful and addictive drug, and nothing here is guidance on its use.

1. Who Friedrich Sertürner Was

Friedrich Wilhelm Adam Sertürner was born on 19 June 1783 at Schloss Neuhaus, the residence of the prince-bishops of Paderborn in Westphalia, now part of the city of Paderborn in Germany. According to the German national biography (Neue Deutsche Biographie), his father, Simon Joseph Sertürner, was a surveyor, map-maker and architect in the prince-bishop’s service. After his father’s death in 1798, the boy began an apprenticeship in 1799 at the Paderborn court pharmacy, and in 1803 he passed his examination as a pharmacist’s assistant.

In 1805 or 1806 (the sources differ) he moved to Einbeck to work in the town council’s pharmacy. Qualified as a pharmacist in 1809, he was able, under the Napoleonic law of the French-ruled Kingdom of Westphalia, to open a pharmacy of his own there; after Napoleon’s defeat that concession lapsed and the shop closed. From 1821 he ran the council pharmacy (Ratsapotheke) in Hameln, and that same year he married Eleonore von Rettberg; they had three sons and four daughters. He was never a professor. Honours came from the University of Jena, which gave him a doctorate in 1817, from learned societies in Germany, Russia and Portugal, and from the Institut de France, which awarded him its Prix Montyon in 1831.

His interests reached far beyond opium: galvanism, firearms, a “system of chemical physics” in the spirit of Romantic natural philosophy, and in 1831 a proposal, as the historian Jurna describes it, that cholera is caused by a poisonous, living, self-reproducing being — a speculation that pointed toward the later germ theory. Jurna writes that in his last years he felt his work was not properly esteemed and that his health declined. He died in Hameln on 20 February 1841 and was buried in Einbeck. The full story is in Friedrich Sertürner: Life and Career.

2. The Discovery on One Page

Opium was one of the most important drugs in any early nineteenth-century pharmacy, yet nobody knew which substance inside it did the work. The Neue Deutsche Biographie relates that, as an apprentice, Sertürner noticed that carefully made opium preparations still varied in strength; Klockgether-Radke notes that because opium’s constituents were unknown, exact dosing was almost impossible. Influenced by the Swedish chemist Carl Wilhelm Scheele, who had isolated a series of acids from plants, Sertürner at first expected opium’s active principle to be an acid.

Instead, around 1804 he obtained a crystalline substance with an alkaline character. He reported it in 1805 in a letter to Trommsdorff’s Journal der Pharmacie and described it further in a second paper there, but Goerig and Schulte am Esch write that this first report went unnoticed. After years of repeated work he published the decisive paper in 1817 in the Annalen der Physik: “On morphium, a new salt-forming base, and meconic acid, as the main constituents of opium.” The title states both claims — that morphium was a base able to form salts, and that meconic acid was opium’s other main constituent. Klockgether-Radke states that he proved in animals and in humans that the compound was opium’s principium somniferum, its sleep-making principle.

The human test is told as history only. Papini, drawing on Sertürner’s own description, recounts that he took the dissolved substance himself together with three young men, and that the trial nearly ended in disaster, with stomach pain, exhaustion and a severe narcosis close to fainting. The French chemist Gay-Lussac arranged a French translation of the 1817 paper, which brought the discovery to wide attention, and Franz Anton Choulant published a confirmation of the new alkali. The French pharmacists Derosne and Seguin also obtained crystalline material from opium in those years; historians such as Hosztafi review the priority claims, and the literature credits Sertürner as the first to recognise and describe a plant base. The year of the discovery is itself debated, with sources giving dates from 1803 to 1806. The whole account is in The Isolation of Morphine.

3. The Natural Source: The Opium Poppy

Opium is the air-dried latex of the seed capsule of the opium poppy, Papaver somniferum — the “sleep-bearing” poppy. Brook and colleagues date human use of opium back to the sixth millennium BCE. Norn and co-authors trace its written history from a Sumerian clay tablet of about 2100 BCE, which some scholars believe refers to the poppy, through Theophrastus, Dioscorides, Celsus, Galen and Avicenna, to theriac, the famous compound remedy in which opium was one of dozens of ingredients. Seventeenth-century physicians knew it as laudanum, an opium tincture; the site’s Sydenham’s Laudanum page tells that chapter.

Opium is a variable mixture of several alkaloids — morphine, codeine, thebaine, papaverine and noscapine among them — and their proportions differ from one batch to the next, which is exactly the problem Sertürner set out to solve. Chemically, morphine is a benzylisoquinoline alkaloid, a family the poppy assembles step by step from the amino acid tyrosine and which also includes berberine. Beaudoin and Facchini note that the opium poppy remains the only commercial source of morphine and codeine and of the semisynthetic drugs made from them. Sir Robert Robinson worked out morphine’s structure in the 1920s and Gates and Tschudi reported its first total synthesis in 1952, yet Brook and colleagues write that chemical synthesis still cannot compete with extraction from the plant. The plant side of the story is in The Opium Poppy and the Chemistry of Morphine.

4. The Alkaloid Revolution

Before morphine, chemists widely held that plants could not contain bases. Hosztafi’s history of the discovery of alkaloids describes how the recognition of a nitrogen-containing plant “alkali” that neutralised acids to form salts overturned that view, and opened a search for the active principles of other medicinal plants. Within two decades a run of alkaloids followed. In 1820 the Paris pharmacists Pierre Joseph Pelletier and Joseph Caventou isolated quinine from cinchona bark, the traditional fever remedy for malaria, and in 1832 Pierre-Jean Robiquet isolated codeine, a second opium alkaloid.

The Neue Deutsche Biographie describes Sertürner’s discovery as a starting point for the rise of the chemical-pharmaceutical factories, and Papini records morphine being prepared on a commercial scale by 1833. Goerig and Schulte am Esch count Sertürner among the co-founders of alkaloid chemistry, and see his work as part of pharmacy’s move from alchemy to science: for the first time a plant medicine could be given as one defined, weighable compound instead of a mixture of unknown strength. That chain, from medicinal plant to purified molecule, runs through much of modern pharmacology. It is told in The Alkaloid Revolution and Morphine in Medicine.

6. Later Significance: Morphine in Medicine and the Addiction Findings

Klockgether-Radke describes morphine as the first pure opioid that allowed pain to be treated with a single defined compound. Hamilton and Baskett write that its use became widespread only after the hypodermic needle and syringe arrived, nearly fifty years after its isolation; the Edinburgh physician Alexander Wood published his method of injecting opiates directly at painful points in 1855. In the decades that followed, injected morphine spread through military and civilian medicine, and so did dependence on it. Papini traces the first US federal controls, the Smoking Opium Exclusion Act of 1909 and the Harrison Narcotics Act of 1914, and the story of heroin, diacetylmorphine, sold from 1898 as a supposedly non-addictive substitute for morphine before its own addictiveness was recognised.

A century and a half after Sertürner, scientists found out why morphine acts on the body at all. In 1973 Candace Pert and Solomon Snyder demonstrated a specific opiate receptor in nervous tissue, and in 1975 John Hughes, Hans Kosterlitz and colleagues identified the enkephalins, short peptides the brain makes itself that act on the same receptors. Hamilton and Baskett described morphine in 2000 as still the most widely used analgesic and the standard against which new opioids for pain after surgery are compared. The modern evidence on long-term use is sobering: a 2015 systematic review for a US National Institutes of Health workshop by Chou and colleagues found the evidence insufficient to determine whether long-term opioid therapy improves chronic pain and function, while finding a dose-dependent risk of serious harms including overdose, opioid abuse, fractures and heart attack. Norn and co-authors note that the long search for a non-addictive opiate has not succeeded. The site covers these risks on its Opioid Overdose and Opioids for Chronic Non-Cancer Pain pages.
