An older or alternative spelling/form of cinchonine, a major alkaloid compound found in cinchona bark with medicinal properties.
From cinchona + -in (common alkaloid suffix, variant of -ine), representing an earlier naming convention in 19th-century chemistry. Both 'cinchonin' and 'cinchonine' refer to the same compound with different nomenclature styles.
Scientific nomenclature wasn't standardized in the early 1800s, so chemists sometimes disagreed on whether to write 'cinchonin' or 'cinchonine'—kind of like how people still write 'ketchup' and 'catsup' interchangeably.
