Embodiment 1

[0026] S1. Extraction: take pomelo peel, cut it into blocks with a size of 4-8 square centimeters, dry it, take 10kg and put it into a gauze bag, then take 3kg of the stem-leaf mixture of mugwort and 3kg of mint leaves and put it into the other two bags respectively. Put them in different gauze bags, place them in a steam distillation device, add water to submerge the sample by about 7cm, introduce water vapor in time during the heating process, and extract for 5h;

[0027] S2. Separation: Receive the distillate through condensing equipment, which is a mixture of volatile oil and water. After standing still, emulsification occurs. After prolonged storage for 1 hour, there is still partial emulsification. Add a small amount of sodium chloride to it to achieve demulsification. Release The lower layer of liquid, the upper layer of yellow-green oily liquid is reserved;

[0028] S3, drying: put the yellow-green oily liquid in the upper layer obtained in step S2 into a centrifuge, a...

Embodiment 2

[0030] S1. Extraction: Take pomelo peel, cut into blocks of 4-8 square centimeters in size, dry, take 10 kg and put it into a gauze bag, then take 5 kg of the stem-leaf mixture of mugwort and 4 kg of mint leaves and put it into the other two bags respectively. Put them in different gauze bags, place them in a steam distillation device, add water to submerge the sample for about 10cm, introduce water vapor in time during the heating process, and extract for 6h;

[0031] S2. Separation: Receive the distillate through condensing equipment, which is a mixture of volatile oil and water. After standing still, emulsification occurs. After prolonged storage for 1 hour, there is still partial emulsification. Add a small amount of sodium chloride to it to achieve demulsification.

Embodiment 3

[0034] S1. Extraction: Take pomelo peel, cut into blocks with a size of 4-8 square centimeters, dry, take 10 kg and put it into a gauze bag, then take 7 kg of the stem-leaf mixture of mugwort and 6 kg of mint leaves and put it into the other two bags respectively. Put them in different gauze bags, place them in a steam distillation device, add water to submerge the sample for about 15cm, introduce water vapor in time during the heating process, and extract for 7h;

[0035] S2. Separation: Receive the distillate through condensing equipment, which is a mixture of volatile oil and water. After standing still, emulsification occurs. After prolonged storage for 1 hour, there is still partial emulsification. Add a small amount of sodium chloride to it to achieve demulsification. Release The lower layer of liquid, the upper layer of yellow-green oily liquid is reserved;

Abstract

The invention discloses a preparation method of sedative composite volatile oil, and the method comprises the steps of extraction, separation and drying, is simple in process and low in loss, and can be repeatedly used by subpackaging three raw materials during extraction. After extraction treatment, dregs are taken out, aired and dried, and shaddock peel dregs can be subjected to subsequent treatment such as peel general flavone extraction, so the utilization rate of shaddock peel is greatly increased, and waste is avoided; the finally prepared composite volatile oil comprehensively and synergistically improves the characteristics of the wormwood essential oil, the mint essential oil and the shaddock peel essential oil, and has the effects of calming, relieving itching and the like.

Description

technical field [0001] The invention relates to a preparation method of volatile oil, in particular to a method for extracting and preparing compound volatile oils: wormwood essential oil, peppermint essential oil and pomelo peel essential oil, and belongs to the technical field of plant extraction and daily chemical. Background technique [0002] Volatile oil, also known as essential oil, is a general term for a class of oily liquids with an aromatic smell. Its main chemical components are semiterpenes, sesquiterpenes, small molecular ketones, phenols, acids, etc., and have a wide range of biological activities. [0003] Essential oil extraction methods include steam distillation, leaching, and cold pressing. Among them, steam distillation is the preferred method for essential oil extraction due to its simple equipment, easy operation, low cost, and high yield. However, the preparation process in the prior art is relatively complicated and consumes a lot, and needs to be i...
