Aporphine alkaloids and feruloylamides from the bark of Xylopia benthamii R.E. Fries (Annonaceae).
Pimenta LP, Mendonça DD. Pimenta LP, et al. Nat Prod Res. 2012;26(20):1948-50. doi: 10.1080/14786419.2011.628667. Epub 2011 Oct 19. Nat Prod Res. 2012. PMID: 22007762
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 …
