Interpretive Summary: The flowering head of Chrysanthemum morifolium Ramat (Compositae) is an important traditional Chinese medicine that is also used as herb tea and considered a healthy food. It contains a high concentration of flavonoid and phenolic acid derivatives that are considered to be health promoting in humans. Limited studies have focused on the identification and quantification of some of these compounds. This study presents a detailed identification of the main phenolic components of this flower. More than ten phenolic compounds are reported for the first time. These results are a valuable contribution to an herbal database, enhance understanding of the biological activity of herbs, and should lead toan increased ability of researchers to evaluate their potential roles in health.

Technical Abstract: A standardized LC-DAD-ESI/MS method was used to detect 31 phenolic compounds in the extract of chrysanthemum flowers (Chrysanthemum morifolium Ramat) (Compositae), an important Chinese traditional medicine. Of these phenolic compounds, 7 caffeoylquinic acids (3-, 4, 5-mono-, 3,4-, 3,5-, 1,5-, and 4,5-dicaffoylquinic acids) and 12 flavonoids (apigenin, luteolin, diosmetin, acacetin, eupatorin, apigenin 7-O-glucoside, apigenin 7-O-rutinoside, acacetin 7-O-rutinoside, diosmetin 7-O-rutinoside, luteolin 7-O-glucoside, quercetin 3-O-glucoside, eriodictyol 7-O-glucoside) were positively identified. The identification of luteolin 7-O-rutinoside, luteolin 7-O-glucuronide and its malonate, diosmetin 7-O-glucoside and its malonate, diosmetin 7-O-glucuronide, acecetin 7-O-galacoside and its malonyl, acetyl, and acetyl-malonyl derivatives, as well as apigenin 7-O-6'-malonylglucoside was made by detailed analysis of their UV and mass spectral data and reference to published information. This is the first report of 10 of these phenolic compounds in chrysanthemum flowers.
