Extraction method of chrysanthemum morifolium volatile oil

The invention discloses an extraction method of chrysanthemum morifolium volatile oil. The extraction method comprises the following steps: acquiring chrysanthemum morifolium powder; extracting chrysanthemum morifolium volatile oil; and acquiring the chrysanthemum morifolium volatile oil. Volatile oil of dry chrysanthemum morifolium is extracted with a steam distillation method, volatile components are distilled out together with steam in a steam distillation manner and are condensed and separated, equipment is simple and convenient, and the extraction cost of the volatile oil is reduced. The distillation time is short, only a sodium chloride solution is used as an extracting agent, the whole process is environment-friendly and energy-saving, and troublesome steps including filtering, decompression, concentration, alcohol precipitation, purification and the like when an organic solvent is used are reduced; meanwhile, pollution of the volatile oil due to incomplete taking out of the organic solvent is avoided, and influence on human body safety during later use is avoided.
