 | | It was soon established beyond a doubt, however, that this morning glory in reality was a veritable factory of hallucinogenic lysergic acid derivatives: the principal psychotomimetic principle, ergine or d-lysergic acid amide; an alkaloid of secondary importance, isoergine or d-isolysergic acid amide; as well as chanoclavine, elymoclavine and lysergol, all apparently without psychotomimetic effects. |
 | | They have been found to contain the same or similar lysergic acid derivatives as those isolated from Rivea corymbosa: ergine, isoergine, chanoclavine, elymoclavine; lysergol was not present; while ergometrine, a strong uterotonic and hemostatic alkaloid known from ergot, is a constituent of Ipomoea violacea but not of R. |
 | | It is interesting that, once the hallucinogenic properties of the Mexican morning glories became common knowledge, certain fringe groups in European and American society began to ingest convolvulaceous seeds, mainly horticultural varieties of sundry morning glories, procuring their supplies primarily from the nursery and garden industry. |
