Lophophora williamsii, also knows as peyote or peyotel, is a slow growing spineless cactus with psychoactive alkaloids like mescaline and pellotine.[1] Native North Americans are likely to have used peyote, often for spiritual purposes, for at least 5,500 years.[2]

Alkaloids in different Lophophora species

According to the study by Dr. Štarha,[3] all varieties of peyote contain approximately 0.7 mg of mescaline per gram of living plant. Both Lophophora diffusa and Lophophora fricii are found to be low in mescaline and high in pellotine.

Alkaloid L. williamsii L. jourdaniana L. diffusa L. fricii L. koehresii
Tyramine 0.5 - 1 0.6 0.1 0.1 0.1
Hordenine 5 - 8 2 - 9 0.5 0.4 0.4
