Psychotria colorata

Fractionation of an alkaloid extract of Psychotria colorata flowers led to the isolation of six alkaloids, one of which was unknown. The new pyrrolidinoindoline alkaloid was, in part, characterized through the use of long-range GHMBC data as... [Pg.433]

An ethnopharmacological survey was conducted in order to chemically investigate a Psychotria species, P. colorata, for analgesic activity. The plant is used by the caboclos, local rural communities in the state of Para, northern Brazil, to alleviate pain. The molecules discovered in this plant were the first of a fruitful endeavor phytochemical prospection of Psychotria species. [Pg.127]

P. umbellata is a woody species that occurs in the Brazilian Southern Coast Atlantic Forest [122]. Due to promising results with P. colorata, investigations of Southern Brazilian subtropical species of Psychotria were performed, including P. umbellata, a dose-dependent opioid-like analgesic activity was described for the foliar ethanolic extract from the latter species [123]. [Pg.136]
