Abstract:
The chlorogenic acids of four plants of the Astreraceae family, Rudbeckia hirta (black‐eyed Susan), Helianthus tuberosus (Jerusalam artichoke), Carlina acaulis and Symphyotrichum novae‐angliae were investigated qualitatively by LC‐MS n . Fifty‐two chlorogenic acids were detected and all characterised to regioisomeric level on the basis of their fragmentation pattern in the tandem MS spectra, all of them for the first time from these sources with three of them previously not reported in nature. Both chlorogenic acids based on trans ‐ and cis ‐cinnamic acid substituents were identified, including mono‐, di‐ and tri‐acyl quinic acids and caffeoylshikimic acid.
