Isolation of a deoxy lupane triterpene carboxylic acid from Finlaysonia obovata (a mangrove plant)

A deoxy lupane triterpene carboxylic acid, lup-20(29)-en-24-oic acid (1), was isolated from the active chloroform extract of Finlaysonia obovata, a latex exuding mangrove plant. Its structure was evaluated on the basis of different spectroscopic methods, including extensive 1D and 2D NMR spectroscopy. Lup-20(29)-en-24-oic acid (1) has shown moderate antimicrobial activity, against some fish pathogens.

The structure of a new 3-deoxy lupane triterpene carboxylic acid, isolated from Finlaysonia obovata, a latex exuding mangrove plant was evaluated on the basis of different spectroscopic methods, including extensive 1D and 2D NMR spectroscopy.Figure optionsDownload as PowerPoint slide
