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.

Author information: (1)Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing 100093, China. OBJECTIVE: To investigate the chemical constituents in the roots of Polygonum amplexicaule var. sinense. METHOD: The compounds were isolated by column chromatography on silica gel and Sephadex LH-20. The structures were identified by means of IR, 1H-NMR, 13C-NMR and MS analyses. RESULT: Eight compounds were isolated and identified as friedelin (1), beta-sitosterol (2), simiarenone (3), angelicin (4), psoralen (5), palmitic acid (6), (-)-epicatechin (7), and quercetin (8), respectively. CONCLUSION: All compounds were isolated from this species for the first time and compounds 1, 3-6 were obtained from this genus for the first time. PMID: 19385182 [Indexed for MEDLINE]
