Embodiment 1

[0024] A method for extracting thuja essential oil, comprising the following steps:

[0025] S1. Excise the dry skin of the thuja raw material surface layer, then slice and crush to obtain thuja fragments;

[0026] S2, the thuja fragments are put into the centrifuge tube, then placed in the centrifuge tube accommodation chamber of the vacuum centrifuge for vacuum centrifugation, the rotating speed of the vacuum centrifuge is 15000r / min, and the vacuum degree of the vacuum centrifuge is 0.08Mpa, The time of vacuum centrifugation was 5 minutes to obtain the thuja essential oil, and the extraction rate was calculated. Extraction rate of essential oil = content of essential oil in thuja / weight of thuja × 100%.

[0027] Adopt above-mentioned extraction method, the extraction rate of thuja essential oil is 14%.

Embodiment 2

[0029] A method for extracting thuja essential oil, comprising the following steps:

[0030] S1. Excise the dry skin of the thuja raw material surface layer, then slice and crush to obtain thuja fragments;

[0031] S2, the thuja fragments are put into the centrifuge tube, then placed in the centrifuge tube accommodation chamber of the vacuum centrifuge to carry out vacuum centrifugation, the rotating speed of the vacuum centrifuge is 10000r / min, and the vacuum degree of the vacuum centrifuge is 0.02Mpa, The vacuum centrifugation time is 2min, and the thuja essential oil is obtained, and the extraction rate is calculated. Extraction rate of essential oil = content of essential oil in thuja / weight of thuja × 100%.

[0032] Adopt above-mentioned extraction method, the extraction rate of thuja essential oil is 10%.

Embodiment 3

[0034] A method for extracting thuja essential oil, comprising the following steps:

[0035] S1. Excise the dry skin of the thuja raw material surface layer, then slice and crush to obtain thuja fragments;

[0036] S2, the thuja fragments are put into the centrifuge tube, then placed in the centrifuge tube accommodation chamber of the vacuum centrifuge for vacuum centrifugation, the rotating speed of the vacuum centrifuge is 20000r / min, and the vacuum degree of the vacuum centrifuge is 0.1Mpa, The time of vacuum centrifugation is 8min, and the thuja essential oil is obtained, and the extraction rate is calculated. Extraction rate of essential oil = content of essential oil in thuja / weight of thuja × 100%.

[0037] Adopt above-mentioned extraction method, the extraction rate of thuja essential oil is 13%.

Abstract

The invention discloses an extraction method of Thuja sutchuenensis essential oil. The extraction method comprises the following steps: S1, peeling off dried bark on the surface layer of a Thuja sutchuenensis raw material, and carrying out slicing and pulverizing to obtain Thuja sutchuenensis fragments; and S2, putting the Thuja sutchuenensis fragments into a centrifuge tube, and then putting thecentrifuge tube into a centrifuge tube accommodating chamber of a vacuum centrifuge for vacuum centrifugal treatment to obtain the Thuja sutchuenensis essential oil. The invention also discloses a device for realizing the Thuja sutchuenensis essential oil extraction method. The extraction method of the Thuja sutchuenensis essential oil is simple in process; and the extracted essential oil is highin yield and low in cost, and produces good economic benefits.

Description

technical field [0001] The invention relates to the technical field of extraction of thuja essential oil, in particular to a method for extracting thuja essential oil and a device thereof. Background technique [0002] Thuja sutcheenensis Franch. is an evergreen tree belonging to the genus Thujasutchueensis of Cupressaceae. Its distribution range is very small, mainly in Taihang Mountains, Sichuan, Chongqing and other places. According to data, thuja grows in limestone mountains at an altitude of 1,400 meters. It comes from the age of dinosaurs. It is a Cretaceous creature with a history of 300 million years. It can be said to be a living fossil of plants. It has not yet been artificially introduced and cultivated. Cupressaceae plants have a wide range of biological activities such as hemostasis, antitussive and expectorant, bronchial expansion, antibacterial, anti-tumor, and anti-oxidation. Studies have shown that thuja alcohol has obvious inhibitory effect on bacteria, es...
