Abstract
Abstract Three new flavonoids (hoslundin 1 , hoslundal 4 , and hoslunddiol 6 ) have been isolated from the twigs of Hoslundia opposita . The structure of hoslundin has been determined mainly by the use of 2D n.m.r. long-range δ C /δ H correlation in conjunction with the ID proton-coupled 13 C n.m.r. spectrum, while the structures of the rest were established using 1 H and 13 C n.m.r. spectroscopy. The manner in which 2D n.m.r. long-range δ C /δ H H correlation experiments are used for determining bond connectivity during the process of structural elucidation is discussed.
