Temporin

Short description: Peptide secretion

Secretion of temporins visible on an African elephant during musth (2007).

Temporins are a family of peptides isolated originally from the skin secretion of the European red frog, Rana temporaria.^[1] Peptides belonging to the temporin family have been isolated also from closely related North American frogs, such as Rana sphenocephala.^[2]

In elephants, temporin is secreted by temporal glands during the period of musth. It contains proteins, lipids (notably cholesterol), phenols, cresols and sesquiterpenes (notably farnesol and its derivatives).^[3] This is not related to temporins that are antimicrobial peptides.

In old Sanskrit texts, it is referred to as rut fluid (dāna, or mada) and is considered to be a symbol of potency and vigour.^[4]

However, from the point of view of ancient Indian elephant science (gajaśāstra), temporin is not a direct symptom of rut.^[5]
