摘要: Two new macrocyclic alkaloids oncinotine (1) and isooncinotine (2) have been isolated from Oncinotis nitida BENTH. 1 can be converted into 2 by an amide exchange reaction. The spermidine residue was present in both bases. structural elucidation based mainly on (I) the determination of functional groups, (II) degradation to compounds 12 13 (III) mass spectrometric investigation above mentioned products.
