Extraction and Analysis on Volatile Constituents of the Chrysanthemum Indicum L. from Huangshan

Distillation extraction method and simultaneous distillation extraction method were used for extracting the volatilecompounds of Chrysanthemum indicum L. from Huangshan. The average oil yield obtained by distillation extraction method was2.83% and by simultaneous distillation extraction method was 3.73%, 37 chemical components and 28 chemical components wereidentified by gas chromatography/massspectrometry (GC/MS) method respectively. The contents of the identified compoundsmake up 63.16% of the total volatile substances detected by distillation extraction method and 61.16% by simultaneous distillationextraction method. The contents of the volatile compounds of the volatile components were determined using the normalizationmethod.
