Worldwide, there are plants known as psychoactive plants that naturally contain psychedelic active components. They have a high concentration of neuroprotective substances that can interact with the nervous system to produce psychedelic effects. Despite these plants' hazardous potential, recreational use of them is on the rise because of their psychoactive properties. Early neuroscience studies relied heavily on psychoactive plants and plant natural products (NPs), and both recreational and hazardous NPs have contributed significantly to the understanding of almost all neurotransmitter systems. Worldwide, there are many plants that contain psychoactive properties, and people have been using them for ages. Psychoactive plant compounds may significantly alter how people perceive the world.

Preininger V, Thakur RS, Santavý F. From Corydalis cava (L.) Sch. et K. (C. tuberosa DC) (Papaveraceae: genus Corydalis Med.), a mixture of alkaloids (0.53%) was isolated. The main alkaloid was (+)-bulbocapnine, and the minor alkaloids were coptisine, (+)-domestine, adlumidiceine, (+)-predicentrine, protopine, (-)-capnoidine, (+)-stylopine, (+)-isoboldine, 8-oxocoptisine, 1,2-methylenedioxy-6a,7-dehydroaporphine-10,11-quinone, and corysamine. In addition, fumaric acid was obtained. Coptisine, adlumidiceine, predicentrine, 8-oxocoptisine, corysamine, 1,2-methylenedioxy-6a, 7-dehydroaporphine-10,11-quinone, and isoboldine were found in C. cava for the first time, but rhoeadine and papaverrubine alkaloids were not detected. Predicentrine and isoboldine were identified on the basis of the UV, IR, mass, and PMR spectra. DOI: 10.1002/jps.2600650230 PMID: 1255467 [Indexed for MEDLINE]
