Abstract:
Uvaria narum has been used for gastrointestinal problems, jaundice, fever and skin diseases in traditional and ethnomedical practices. Our preliminary antifungal screening of various leaf extracts of U. narum revealed very good antifungal activity for its acetone extract. Active principle of U. narum leaf acetone extract was isolated by bioactivity-guided fractionation and characterised as a new molecule, 2-E-(2″-oxo-5″-acetoxy cyclopent-3″-en-1″-ylidene) ethyl benzoate, by NMR, IR and mass spectroscopic analyses. This active isolate showed very good activity against the fungal pathogen, Colletotrichum gloeosporioides.
