Triacylglycerols of the lipid fraction from fruits of two Echinacea species

Fatty oils extracted from the fruits of Echinacea purpurea and E. pallida species have been analyzed. The extracts represent oily and readily mobile light yellow liquids. Fruits of E. purpurea contain 33.6% fatty oil; of E. pallida, 23.2%. NMR spectroscopy analyses of fatty oils from fruits of the two Echinacea species show that these substances belong to liquid plant oils such as linoleic acid, which is confirmed by the measured numerical indices. © 2009 Springer Science+Business Media, Inc.
