摘要：
Parahancornia amapa (Apocynaceae) is typical of the Amazon region and popularly known as amapazeiro and widely used in folk medicine in the Amazon region. The objective of this work was to study the phytochemical composition of twigs and barks of this species. From the dichloromethane extract of twigs were isolated A-sitosterol, stigmasterol, and pentacyclic triterpenoids alpha-amyrin, beta-amyrin, lupeol and friedelin. From the methanol extract of barks was isolated indole alkaloid isositsiriquina. The structures of these compounds were identified by analysis of the mass spectra high-resolution, H-1 and C-13 NMR and comparisons with literature data. This is the first report of isolation of alkaloid in this genus.
