From extracts of Oncinotis tenuiloba STAPF, two novel polyamine alkaloids, oncinotin-1 1-one (5) and oncinotin-12-one (6), were isolated. Peracetylation of 6 provided the N-acetyl derivative 11 as well as N,N'-diacetylinandenin-10-en-12-one (12) due to ab-elimination-type side reaction resulting in
