A New Method for Preparation and Characterization of Lipo-alkaloid

摘要

A simple route for the preparation of lipo-alkaloid is presented. When aconitine or one of its analogues is heated with a fatty acid for 20 min at 100℃ in water, the C_8 acetyl group of aconitine is displaced by a long chain fatty acyl group. The structures of the products were characterized by electrospray ionization tandem mass spectrometry.
