Plant Diversity and Evolution

Two lactone compounds have been isolated from the leaves and branches of ylang-ylang (Cananga odorata forma genuina Hook. f. et Thomson, Annonaceae). One was already known as isosiphonodin 1. The other, canangone 2, is a new terpenoid spirolactone with an unusual backbone. Its structure has been established as 6-hydroxy-1-oxo-2-oxaspiro[4.5]dec-7-ene-8-carbaldehyde by using 1-D and 2-D NMR. Keywords: Cananga odorata; Annonaceae; canangone; spirolactone; isosiphonodin
