Abstract To elucidate the chemical compositions of the aerial parts of Chrysanthemum coronarium L., the ethanol extracts of Ch. coronarium L. were firstly isolated by the MCI-gel resin column. The caffeoylquinic acid-rich fractions were further purified by various chromatographic columns including silica gel, Sephadex LH-20, and semi-preparative HPLC to yield the compounds. The purified compounds were characterized by 1H-Nuclear Magnetic Resonance 1H-NMR, 13C-NMR, and high resolution electrospray ionisation mass spectral HR-ESI-MS spectroscopy. Seven caffeoylquinic acid CQA compounds were isolated from this plant. Their structures were clarified by spectrometric methods and identified as 3-O-caffeoylquinic acid 1, 5-O-caffeoylquinic acid 2, 4-O-caffeoylquinic acid 3, 3,4-di-O-caffeoylquinic acid 4, 1,5-di-O-caffeoylquinic acid 5, 3,5-di-O-caffeoylquinic acid 6, and 4,5-di-O-caffeoylquinic acid 7. Caffeoylquinic acids were the major constituents present in the aerial parts of Ch. coronarium L. All of the isolates except for compounds 2 and 6 were reported for the first time from this species. Moreover, compounds 3–5, and 7 were identified from the Chrysanthemum genus for the first time. View Full-Text
