title: A new monoterpene alkaloid and other constituents of Plumeria acutifolia.
abstract: Phytochemical investigation of the methanolic extract of Plumeria acutifolia (Apocynaceae) leaves has led to the isolation and identification by spectroscopic means of a new monoterpene alkaloid, (R)-4'-((S)-1-hydroxyethyl)-5,6-dihydro-5' H-spiro[cyclopenta[C]pyridine-7,2'-furan)-5'-one, for which the name plumerianine was adopted, the iridoid 15-demethylplumeride, and three known triterpenes, i. e., lupeol, uvaol and ursolic acid.
