Bufotoxins are a family of toxic steroid lactones found in the parotoid glands, skin and venom of many toads (genus ''Bufo''); other amphibians; and some plants and mushrooms. The exact composition varies greatly with the specific source of the toxin. It can contain: 5-MeO-DMT, bufagins, bufalin, bufotalin, bufotenin, bufothionine, epinephrine, norepinephrine, and serotonin. The term bufotoxin can also be used specifically to describe the conjugate of a bufagin with suberylargine. The toxic substances found in toads can be divided by chemical structure in two groups: * bufadienolides which are cardiac glycosides (e.g. bufotalin, bufogenin) * tryptamine related substances (e.g. bufotenin) Toads known to secrete bufotoxin are: * ''Bufo alvarius'' * ''Bufo americanus'' * ''Bufo arenarum'' * ''Bufo asper'' * ''Bufo blombergi'' * ''Bufo boreas'' * ''Bufo bufo'' * ''Bufo bufo gargarizans'' * ''Bufo formosus'' * ''Bufo fowleri'' * ''Bufo marinus'' * ''Bufo melanostictus'' * ''Bufo peltocephalus'' * ''Bufo quercicus'' * ''Bufo regularis'' * ''Bufo valliceps'' * ''Bufo viridis'' * ''Bufo vulgaris'' ==Extraction== Extract from the skin of certain Asian toads, such as ''Bufo bufo gargarizans'', is often found in certain Chinese folk remedies. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bufotoxin」の詳細全文を読む スポンサード リンク
