Crush the treated cloves with a small grain grinder. Accurately weigh a certain amount of dried clove powder and place it in a distillation flask, add a certain amount of water in proportion, connect the condenser tube, and start the distillation.

A certain amount of anhydrous diethyl ether was added to the crude clove oil, and the water was separated with a separatory funnel, and then treated with anhydrous sodium sulfate. The ether in clove oil was removed under reduced pressure to obtain a refined clove oil. The extraction rate of clove oil was 9.94%. The volatile oils are light yellow oily liquids with a unique fragrance of clove.

(2) Process flow of clove oleoresin extraction

Clove is crushed, weighed accurately, wrapped in dried filter paper, put into a triangle bottle, added a certain amount of organic solvent in proportion, sealed, placed in a thermostatic water bath at a certain temperature for different times, and then removed Packed with a filter paper and recovered the organic solvent to obtain clove oleoresin. Clove oleoresin is more viscous and less scent than volatile oil.

(3) Supercritical CO2 extraction of clove oil

Clove is pulverized into coarse powder and placed in a CO2 supercritical extraction device. Extraction is performed for 4h under the conditions of Chen Gengfu (2002) Research Institute: pressure is 10MPa, temperature is 40 ° C, and CO2 flow is 22L / h. Analysis was performed at a pressure of 7.0 MPa and a temperature of 45 ° C to obtain clove oil ^[2] .
