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.
