|Abstract:||The CH(2)Cl(2) and MeOH extracts from leaves of Piper caldense were subjected to chromatographic separation procedures to afford the new prenylated benzoic acid, caldensinic acid (3-[(2'E,6'E,10'E)-11'-carboxy-3',7',15'-trimethylhexadeca-2',6',10',14'-tetraenyl]-4,5-dihydroxybenzoic acid) whose structure was determined by spectral analysis, mainly NMR ((1)H, (13)C, HSQC, HMBC) and ESI-MS. the natural compound and derivatives displayed antifungal activity against the phytopathogenic fungi Cladosporium cladosporioides and C. sphaerospermum by direct bioautography.
