[Objective] To research the principal component of volatile oils in FLOS DENDRANTHEMA INDICI,and to provide scientific references for the material basis of pharmacological action of FLOS DENDRANTHEMA INDICI. [Methods] A total of 15 batches of FLOS DENDRANTHEMA INDICI were collected. Volatile oils were extracted by steam distillation method,and analyzed by GC-MS. Comprehensive evaluation was carried out by principal component analysis. [Results]The original information of 23 indexes was summarized by five principal components,including 88. 966% information of the original index. The first principle component( PC1) could be used as the descriptive index of antiasthmatic effects of volatile oils in FLOS DENDRANTHEMA INDICI; the second and third principle components( PC2 and PC3) could be used as the descriptive indexes of analgesic effects and cough relieving effects,respectively. [Conclusions] The common components of volatile oils in FLOS DENDRANTHEMA INDICI were analyzed by principal component analysis,which provided theoretical reference and practical exploration for the antiasthmatic effects,analgesic effects and cough relieving effects of volatile oils in FLOS DENDRANTHEMA INDICI.
