Embodiment Construction

[0022] A method for extracting essential oil from jasmine, said extraction method is achieved through the following steps:

[0023] 1) Add fresh jasmine petals to olive oil to soak, the soaking time is 96h, the material-to-solution ratio is 1:1.5;

[0024] 2) After centrifuging the mixture obtained in step 1), filter the flower water obtained;

[0025] 3) Inject the flower water obtained in step 2) into the extraction device through the feeding device, and after closing the valve on the feeding device, vacuum the extraction device;

[0026] 4) After adding the extractant to the extraction device, repeat the extraction process, the extraction time is 1h, the temperature is 30-50℃, and the pressure is 0.6-0.8MPa;

[0027] 5) The obtained extract is transferred to the evaporation device, and the solvent is separated from the extract and purified.

[0028] The repeated extraction process described in step 4) is: after the first extraction, the material is hydraulically transferred to the eva...

Abstract

The invention relates to a method for extracting essential oil from jasmine flowers, belonging to the field of natural plant processing. The method comprises the following steps: adding fresh jasmine petals in olive oil to soak with a ratio of material to solvent being 1:1.5 to obtain a mixture; carrying out centrifugation on the mixture to obtain a flower solution, then filtering the flower solution; injecting the flower solution into an extraction device through a feeding device, closing the valve of the feeding device, and then carrying out vacuum pumping on the extraction device; adding an extractant in the extraction device, and then carrying out extraction repeatedly to obtain an extract liquor; transferring the extract liquor into an evaporation plant, separating the solvent from the extract, and then purifying. The method has the characteristics of simple technology, safety, health, and high oil yield.

Description

Technical field [0001] The invention relates to a method for extracting essential oil from jasmine, and belongs to the field of natural plant processing. Background technique [0002] Jasmine essential oil is known as the "king of essential oils" and has beneficial features such as conditioning the reproductive system, dry and sensitive skin, diminishing scars, and increasing skin elasticity. Jasmine essential oil has an elegant smell, and has an obvious relaxing effect, which can invigorate the spirit. It is an effective medicine for treating severe mental depression; it also has a good effect on the treatment of diseases of the respiratory system. It can reduce coughing, and it can treat hoarseness and throat. Inflammation is also effective. In addition, it can also be used to relieve the symptoms of muscle pain, sprains and stiffness of the limbs; jasmine essential oil is suitable for caring for dry, oily, irritated and sensitive skin, and increase skin elasticity. However, ...
