'amanitine' originates from the genus name 'Amanita', which is derived from the Greek word 'amanitai', referring to a type of fungus.

'amanitai' transformed into the Latin 'Amanita', and eventually became the modern English word 'amanitine'.

Initially, it referred to a type of fungus, but over time it evolved into its current meaning of a toxic compound found in these fungi.
