Identification of pavinane alkaloids in the genera Argemone and Eschscholzia by GC-MS

Abstract

The alkaloid extracts of three Argemone and four Eschscholzia species were analyzed using GC-MS. The alkaloids were identified based on comparison of their mass spectra with commercial libraries, with reported data in the literature and with spectra of reference compounds.

A total of 23 alkaloids of six structural types were identified. The fragmentation pathway of pavinane alkalloids was used for their identification.
