Mescaline Mescaline Mescaline (3,4,5-trimethoxyphenethylamine) is a naturally occurring psychedelic alkaloid of the phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin. It occurs naturally in the peyote cactus ("Lophophora williamsii"), the San Pedro cactus ("Echinopsis pachanoi"), the Peruvian torch ("Echinopsis peruviana"), and other members of the Cactaceae plant family. It is also found in small amounts in certain members of the Fabaceae (bean) family, including "Acacia berlandieri". However those claims concerning Acacia species have been challenged and have been unsupported in additional analysis. Peyote has been used for at least 5,700 years by Native Americans in
Angelicin are three hypotheses proposed to explain the phenomenon: The phototoxic properties of angelicin were deployed by its use as a natural pesticide and disinfectant. Note that it is difficult to readily determine whether only angelicin poses the highest risk of phototoxicity and photomutagenicity as in plants angelicin always occurs in a mixture with angelicin derivatives, psoralen and other furanocoumarins. Moreover, the furanocoumarin composition of most plant species is not definitely known as well as the toxic properties of some furanocoumarins. Angelicin Angelicin is the parent compound in a family of naturally occurring organic compounds known as the angular furanocoumarins. Structurally,
