Secondary and tertiary isoquinoline alkaloids from Xylopia parviflora. - PhytoChemistry, 67(24), p.2671-2675, 2006 .

From the secondary and tertiary alkaloidal fractions of the root and the bark of Xylopia parviflora (Annonaceae), the isoquinoline alkaloids, 10,11-dihydroxy-1,2-dimethoxynoraporphine and parvinine were isolated, along with 39 known alkaloids. Their structures were determined on the basis of analysis of spectroscopic data
