SDA (4), C27H3406, mp 172-174°C, [oc]d-5.7° (MeOH), was obtained as colorless prisms. All spectral data including H- H COSY,, 3C- H COSY and, 3C- H long-range COSY spectra of SDA suggested the presence of a... [Pg.692]

Furthermore, from the knots of Wistaria brachybotrys, several kinds of oleanane type saponins (101 - 108) were isolated together with isoflavonoids. Of these saponins, wistariasaponins A, Bl, B2, C, D and G were found to be novel saponins, and their structures of sapogenols were elucidated by the long-range COSY spectra and difference NOE... [Pg.247]

The basic skeleton of casearin A (12) was elucidated by H-iH and H-correlated spectroscopy (COSY) and 2D-incredible natural abundance double quantum transfer experiment (INADEQUATE). The positions of ester functions were determined by the long range COSY... [Pg.280]

The locations of the acyl groups on the two glucose residues were assigned by the long-range COSY spectra of camelliatannin D (67)... [Pg.441]

Delayed COSY Correlating coupled homonuclear spins through small couplings. Often used to identify proton correlations over many bonds (>3), hence also known as long-range COSY... [Pg.130]
