ptomaine[ptomaine 词源字典]

ptomaine: [19] Ptomaine denotes etymologically ‘matter from a corpse’. It comes via French ptomaïne from Italian ptomaina, which was based on Greek ptōma ‘corpse’. This in turn was derived from the verb píptein ‘fall’, and originally meant literally ‘fallen body’. The term was coined to name substances produced by decomposing flesh.
