Objective To analyze and evaluate the distribution and dynamic changes of chemical constituents from non-medicinal parts of Chrysanthemum morifolium, and to provide scientific basis for the comprehensive utilization of this medicinal biological resources Methods Ultra-high performance liquid chromatography combined with triple quadrupole electrospray tandem massspectrometry (UPLC-TQ/MS) was applied for measuring amino acids and nucleosides, UV spectrophotometry (UV) was used for determining flavones, and ultra-high performance liquid chromatography along with a diode array detector (UPLC-DAD) was used for analyzing flavones and organic acids of root, stem, and leaves of C. morifolium in different growing periods, respectively. Results There are 13 kinds of amino acids in the root, stem, and leaves, total amino acid content ranges of root > leaves > stem; there were four kinds of nucleosides in leaves while only tow kinds were detected in both root and stem. Total nucleoside content ranges of leaves > root > stem; content ranges of flavones in leaves, root and steam were 9.94%—18.66% in leaves; 5.88%—8.02% in root, and 3.98%—5.41% in stem, respectively. Content ranges of organic acids in leaves, root, and stem were 2.44%—4.94% in leaves, 1.89—2.64% in root, and 1.20%—1.48% in stem, respectively. The content changes of flavones and organic acids were the highest after the flowers were picked with growing. Conclusion There is abundant resources of chemical constituents in non-medicinal parts of C. morifolium,especially in leaves, and it reached the highest resource yield after picking the inflorescence. This research results has provided beneficial reference for the resource utilization of abandoned part of C. morifolium after picking the inflorescence.
