Title: Structure Identification of Five Unknown Dilipo-alkaloids Extracted from Processed Tuber of Aconitum Carmiechaeli by Electrospray Ionization Tandem Mass Spectrometry
Abstract: The alkaloids in processed aconite tuber of Aconitum Carmiechaeli were studied, and five novel alkaloids in extract from processed aconite tuber were found. The first step involved the use of electrospray ionization mass spectrometry (ESI-MS), and then multi-stage tandem mass spectrometry (MSn) was used to provide structural information. Based on their MSn spectra, the structures of the five novel compounds were elucidated to be C3,C8-difatty acid esters of mesaconitine, aconitine and 10-hydroxyaconitine.
