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.

Matsuzaki K(1), Ishii R, Kobiyama K, Kitanaka S. Author information: (1)Research Unit of Pharmacognosy, College of Pharmacy, Nihon University, 7-7-1 Narashinodai, Funabashi, Chiba 274-8555, Japan. New benzophenone and flavonol galloyl glycosides were isolated from an 80% MeOH extract of Psidium guajava L. (Myrtaceae) together with five known quercetin glycosides. The structures of the novel glycosides were elucidated to be 2,4,6-trihydroxybenzophenone 4-O-(6''-O-galloyl)-beta-D: -glucopyranoside (1, guavinoside A), 2,4,6-trihydroxy-3,5-dimethylbenzophenone 4-O-(6''-O-galloyl)-beta-D: -glucopyranoside (2, guavinoside B), and quercetin 3-O-(5''-O-galloyl)-alpha-L: -arabinofuranoside (3, guavinoside C) by NMR, MS, UV, and IR spectroscopies. Isolated phenolic glycosides showed significant inhibitory activities against histamine release from rat peritoneal mast cells, and nitric oxide production from a murine macrophage-like cell line, RAW 264.7.
