[0042] One aspect of the present invention relates to a method for preparing volatile oil, comprising the following steps:
[0043] The first raw material is subjected to the first mixed decoction, and the distillate is collected at the same time to obtain the first distillate; the first distillate is heated to obtain a distillation gas; the distillation gas is kept warm and condensed to obtain a second distillate; centrifuging after adding sodium salt to the second distillate;
[0044] The first raw material includes: Guizhi and Atractylodes Rhizome, or, the first raw material includes Poria cocos, Guizhi, Atractylodes macrocephala and licorice.
[0045] The preparation method of the volatile oil is simple and easy to operate, can clearly separate the volatile oil and water, has high extraction efficiency, and the extracted volatile oil can be stored in medicine for a long time.
[0046] During the second distillation, the method of reflux distillation is adopted to adjust t...
Embodiment 1
[0135] The preparation method of the volatile oil provided by the present embodiment comprises the following steps:
[0136] 1. Weigh 55.2kg of Poria decoction pieces, 41.4kg of Guizhi decoction pieces, 41.4kg of Atractylodes macrocephala decoction pieces and 27.6kg of licorice decoction pieces;
[0137] 2. Add Guizhi decoction pieces and Baizhu decoction pieces, add 414L of drinking water, soak for 1 hour, connect the volatile oil extractor, heat and decoct at 98°C, collect distilled water at the same time, and obtain 120L of distillate after 2 hours;
[0138] 3. Transfer the distillate obtained in step 2 to another extraction tank, connect the 60°C insulation pipe, then connect the 5°C cooler, and finally connect the volatile oil extractor, heat the extraction tank, the steam pressure is 0.2MPa, and collect the distillate , add 0.1 part of sodium chloride to the distillate, centrifuge and filter with suction to obtain 105.5ml of volatile oil.
