Abstract
From the ethanolic extract of the leaves and thin branches of Duguetia trunciflora Maas (Annonaceae) six alkaloids were isolated, being one benzylisoquinoline: reticuline¹, four tetrahydroprotoberberine:,tetrahydro-palmatine², tetrahydrojathrorrizine³, discretamine4, thaicanine5, and one berberine: jathrorrizine6. These alkaloids were identified through ¹H and 13C NMR spectroscopic technics. The alkaloids 1, 3, 5 and 6 are being cited for the first time on Duguetia genus.
