Objective: To establish GC-MS fingerprint determination method of volatile oil from Dendranthema indicum var. aromaticum

and provide the reference for the quality control of D. indicum var. aromaticum medicinal materials. Method: The steam distillation method was used to extract the volatile oil from D. indicum var. aromaticum; the combined technology of GC-MS was used to determin its fingerprints

and Fingerprint Calculation Software of traditional Chinese medicine recommended by State Drug Administration was used for calculation

in order to establish the common fingerprints of volatile oil from D. indicum var. aromaticum. Result: There were 23 main characteristic components in the volatile oil from D. indicum var. aromaticum

and GC-MS fingerprint with these 23 common peaks was established preliminarily. Conclusion: The method is repeatable

accurate and stable

which can be used for quality control of the D. indicum var. aromaticum.
