Introduction Many studies have confirmed the pharmacological effects of Chrysanthemum flowers, but few have assessed the quality from a global market perspective [1], also ensuring product safety [2].

Material and Methods 16 Chrysanthemum indicum L. and 49 Chrysanthemum x morifolium (Ramat.) Hemsl. samples were obtained from the USA, EU and China. Some C. morifolium samples are labeled using their cultivar names.

HPTLC was used to compare general chemical components among samples, and by ICP-OES to quantify heavy metal contamination.

Results The fingerprints of C. indicum samples are clearly distinguishable from those of C. morifolium based on the absence of a zone due to linarin. Different pattern found in their fingerprints do not always correlate with names of medicinal cultivars of C. morifolium. There are differences among the same cultivars collected on markets from different countries (USA and China).

As part of the heavy metal analysis, cadmium levels were most commonly above the accepted limits with no problems identified for lead and arsenic, as well as only one sample showing copper above the limit. In general, the USA samples showed the lowest rate for heavy metal contamination, but sample TAI-2 (C. morifolium) from USA showed by far the highest amount of cadmium. Generally, C. indicum have a higher excessive rates of heavy metals than C. morifolium.

Conclusions Some differences between USA and Chinese samples were observed, which might be ascribable to geographical reasons, e. g., soil conditions, degradation during transport or adulteration. Cadmium contamination is the most serious problem for heavy metal contamination.
