A new dlhydrobenzo[rlphetIuidine alkaloid, 12-methoxydihydnxhelerythrine [l], has been isolated from a lipophilic extract ofthe leaves ofBacconia integnjXa together with three known compounds, dihydrochelerythrine [2], dihydrosanguinarine [3], and dihydnxhelirubine [4]. The structure of 1 was established by analysis of its spectral data (ir, uv, eims, 'H- and I3C-nmr). Extensive 'H-, I3C-, and nOe 1D and 2D nmr experiments allowed 'H and I3C assignments for 14. This is the first report of I3C-nmr assignments for compounds 24.
