Serotobenine, a novel phenolic amide from safflower seeds (Carthamus tinctorius L.).

Abstract

The structure of a new indole derivative, serotobenine (1), from safflower meal (Carthamus tinctorius L.) is proposed based on 1H- and 13C-NMR spectral data and X-ray crystallography. The known compounds N-feruloyltryptamine (2) and N-(p-coumaroyl)tryptamine (3) were also isolated and identified.
