Definition

Noun: 1. A bitter, poisonous alkaloid: Brucine is a toxic, crystalline substance found primarily in the seeds of the Strychnos nux-vomica tree. It is chemically similar to strychnine but is less potent.

Usage

• Brucine is used in scientific research and, in very small, controlled amounts, has some historical use in medicine.
• It is primarily discussed in contexts of toxicology, chemistry, and botany due to its poisonous nature.

Examples

• The forensic analysis detected traces of brucine in the substance.
• Brucine is often mentioned alongside strychnine in textbooks on plant alkaloids.
• The extreme bitterness of brucine makes it a denaturant for some industrial alcohols.

Advanced Usage

• As a chemical reagent: In analytical chemistry, brucine is sometimes used to test for and quantify nitrates.

Variants and Related Words

• Strychnine (noun): A more potent and famous alkaloid poison from the same source plant, often discussed in relation to brucine.
• Alkaloid (noun): The class of naturally occurring chemical compounds to which brucine belongs.
• Nux vomica (noun): The seed of the tree, which is the primary natural source of brucine.

Synonyms

• Toxin (noun): A general term for a poisonous substance.
• Alkaloid poison (noun phrase): Describes its chemical class and effect.

Notes on Meaning

The word "brucine" refers specifically to the chemical compound itself. It is not used in everyday language and is almost exclusively found in technical, scientific, or historical contexts. Its primary defining characteristics are its origin (nux vomica), its bitterness, its toxicity, and its close relationship to strychnine.

Noun

1. a bitter alkaloid poison resembling strychnine and extracted from nux vomica
