Notes:
The previously accepted 13C spectral assignment of hellebrigenin was re-examined and revised signal assignments are proposed for C-1, C-7 and C-11. Results obtained in a (1H, 1H) COSY experiment and NOE experiments enabled us to assign the 1H NMR spectrum of hellebrigenin. The 13C NMR spectrum was subsequently assigned unambiguously by the correlations observed in a 2D (13C, 1H) chemical shift correlation experiment and a COLOC experiment.
