Ergoline - Natural Occurrence

Natural Occurrence

Ergoline alkaloids are found in lower fungi and two species of flowering plants: the Mexican species Rivea corymbosa and Ipomoea violacea of the Convolvulaceae (morning glory) family, the seeds of which were identified as the psychedelic plant drugs known as "ololiuhqui" and "tlitliltzin". The principal alkaloids in the seeds are ergine and its optical isomer isoergine, with several other lysergic acid derivatives and clavines present in lesser amounts. The Hawaiian species Argyreia nervosa includes similar alkaloids. It is possible, though not proven, that ergine or isoergine are responsible for the psychedelic effects. There may be a fungal origin of the ergoline alkaloids also in the Convolvulaceae. Like the ergot alkaloids in some monocot plants, the ergoline alkaloids found in the plant Ipomoea asarifolia (Convolvulaceae) are produced by a seed-transmitted epiphytic clavicipitaceous fungus.

Famous quotes containing the words natural and/or occurrence:

    If photography is allowed to stand in for art in some of its functions it will soon supplant or corrupt it completely thanks to the natural support it will find in the stupidity of the multitude. It must return to its real task, which is to be the servant of the sciences and the arts, but the very humble servant, like printing and shorthand which have neither created nor supplanted literature.
    Charles Baudelaire (1821–1867)

    One is absolutely sickened, not by the crimes that the wicked have committed, but by the punishments that the good have inflicted; and a community is infinitely more brutalised by the habitual employment of punishment than it is by the occasional occurrence of crime.
    Oscar Wilde (1854–1900)
