The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, some dye plants, and ornamental cultivars.
Psychotria is a genus of flowering plants in the family Rubiaceae. It contains 1,582 species and is therefore one of the largest genera of flowering plants. The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests. Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific.

Psychotridine is an alkaloid found in some species of the genus Psychotria, namely Psychotria colorata, but also Psychotria forsteriana, Psychotria lyciiflora, Psychotria oleoides, and Psychotria beccarioides. Psychotridine has analgesic effects and dose-dependently inhibits dizocilpine binding to cortical membranes in vitro, suggesting that it acts as a non-competitive NMDA receptor antagonist.
Psychotrieae is a tribe of flowering plants in the family Rubiaceae and contains about 2114 species in 17 genera. Its representatives are found in the tropics and subtropics.
