C-Geranyl Compounds from <i>Paulownia tomentosa</i> Fruits

Original language description

Five geranylflavonoids, one prenylated flavonoid, and a simple flavanone were isolated from an ethanolic extract of Paulownia tomentosa fruit. Tomentodiplacol (1), 3-O-methyl-5-methoxydiplacol (2), 6-isopentenyl-3-O-methyltaxifolin (3), and dihydrotricin(4) are reported from a natural source for the first time and 3-O-methyldiplacone (6) for the first time from the genus Paulownia. The structures of the compounds were determined by mass spectrometry, including HR-MS, and by 1D and 2D NMR spectroscopy.The cytotoxicity and DPPH (2,2-diphenyl-1-picrylhydrazyl) quenching activity of some of these compounds were tested, with diplacone proving to be the best antioxidant, though the most cytotoxic compound.
