Spermidine alkaloid from Banara parviflora

Abstract Banara parviflora (A. Gray) Benth. is a species that belongs to Salicaceae family and is native to Southern Brazil. Fractionation of the ethanolic extract from Banara parviflora leaves afforded, a new compound identified as N 1 , N 8 -dibenzoylspermidinyl- N 4 -acetamide, a spermidine alkaloid. The structure was elucidated by spectroscopic methods (IR, MS, 1 H, 13 C and 2-D NMR).
