Aporphine alkaloids and feruloylamides from the bark of Xylopia benthamii R.E. Fries (Annonaceae).
The bark of Xylopia benthamii R.E. Fries was investigated in a search for new bioactive compounds. The ethanolic extract of the air-dried bark of X. benthamii was obtained and submitted to an acidic extraction procedure to obtain an alkaloid mixture. Chromatographic fractionation led to the isolation of two aporphine alkaloids, nornantenine and laurotetanine, and a mixture of trans- and cis-feruloyltyramine, isolated for the first time in this genus. Structures were established by spectroscopic methods as NMR (1D and 2D) and mass spectrometry (ESI-MS).
