Canangalias C-H, juvenile hormone III analogues from the roots of Cananga latifolia

Chemical investigation of the roots of Cananga latifolia led to the isolation and purification of thirteen juvenile hormone III analogues. Six new analogues, canangalias C-H (1–6) and a new natural product, (2E,6E,10R)-10-acetoxy-11-hydroxy-3,7,11-trimethyldodeca-2,6-dienoic acid methyl ester (7), were isolated. In addition, six known juvenile hormone III analogues were isolated. Their structures were established by spectroscopic methods including 1D and 2D NMR, IR and mass spectrometry.
