First study on the pyrrolizidine alkaloids of Pardoglossum cheirifolium (L.) E.Barbier & Mathez.: GC-MS analysis of their volatile components in the whole plant

Abstract

In this work, the first study on the pyrrolizidine alkaloids content of Pardoglossum cheirifolium (L.) E.Barbier & Mathez. was reported. The studied exemplar was collected in Algeria and the analysis was carried out by means of GC-MS on the crude base extract deriving from the whole plant. Nine compounds were tentatively identified and they all represent new phytochemicals at the species level. Their presence confirms the botanical classification of the plant as a member of the Boraginaceae family. In addition, it points out some interesting chemosystematic relations within the family.
