Abstract
A new dimeric aporphine alkaloid, phoenicanthusine (1), and six known alkaloids were isolated from the stem bark of Phoenicanthus obliqua. The structure of 1 was elucidated by 1D (1H, 13C) and 2D (1H− 1H COSY, HMQC, HMBC, and NOESY) NMR and HRMS studies. Phoenicanthusine represents the first example of a N-6−C-4‘ and C-7−C-5‘ linked dimeric aporphine alkaloid.Keywords
