What does brucine mean?
Brucine is a bitter, poisonous alkaloid obtained principally from the seeds of Strychnos nux-vomica, the same plant that yields strychnine. Chemically it is a dimethoxy derivative of strychnine and shares its structure, but it is significantly less toxic, producing similar convulsant effects only at much larger doses. Because it crystallizes well and forms salts with optically active acids, brucine was historically valued by chemists as a resolving agent for separating racemic mixtures, and its sulfate was once used in tonics before safer alternatives appeared. The word entered English in the early nineteenth century, honouring the Scottish traveller James Bruce, whose African journeys were connected with the plant's early study. Today brucine appears mainly in pharmacology, forensic toxicology, and analytical chemistry, where it occasionally serves as an internal standard or reagent. It remains a word of strictly scientific register, unfamiliar outside specialist contexts.
nounA bitter, poisonous alkaloid obtained chiefly from nux vomica seeds, closely related to strychnine but less toxic; used historically in medicine and as a denaturant and analytical reagent.
- A bitter, toxic alkaloid C23H26N2O4 found in nux vomica seeds, a dimethoxy analogue of strychnine, used in chemistry (e.g. as a chiral resolving agent) and formerly in medicine.
"The chemist isolated brucine from the seeds of Strychnos nux-vomica for use as a chiral resolving agent."
"Brucine is markedly less toxic than strychnine, though it still acts on the spinal cord in large doses."
"Organic chemists once relied on brucine to resolve racemic mixtures into their enantiomers."
Rarely pluralized; the plural occurs mainly when referring to different derivatives, salts, or prepared samples of the alkaloid.
"The laboratory stocked several brucines for use in resolution experiments."
Named after Scottish explorer James Bruce — who wrongly believed he'd discovered the source of the deadly nux vomica tree on his African travels.

Etymology of brucine
The word 'brucine' was coined in the early nineteenth century from the name of James Bruce (1730–1794), the Scottish explorer whose travels brought attention to the nux vomica tree, combined with the chemical suffix '-ine' characteristic of alkaloids such as morphine and quinine. It belongs to the same family of alkaloid names derived from sources or discoverers rather than classical roots. Its closest lexical relative is 'strychnine', coined around the same period for the more famous alkaloid of the same seed.
How brucine is actually used
Strictly technical register, encountered in pharmacology, toxicology, and organic chemistry; rare in everyday speech. Often discussed in contrast with strychnine because both occur together in Strychnos species.
Easily confused with brucine
Strychnine is the far more toxic alkaloid from the same nux vomica seeds, whereas brucine is a closely related but considerably less poisonous dimethoxy analogue.
