Problems solved by technology

[0006] For essential oil extraction, currently commonly used methods are steam distillation and solvent extraction, but there are disadvantages such as low absorption rate, low purity and toxic solvent residue, low purity of tea tree essential oil, cumbersome process, and not suitable for mass production, so it is necessary to develop A preparation method with high extraction and purification efficiency, simple process, and high content of tea tree essential oil is difficult to meet the current requirements of the essential oil industry for high-quality essential oil, so it is imperative to explore new alternative technologies

Embodiment 1

[0025] The present embodiment provides a method for extracting Australian tea tree essential oil, which is characterized in that it comprises the following steps:

[0026] (1) Raw material collection: select fresh tea tree leaves and fresh young shoots, the ratio of tea tree leaves to young shoots is 3:1;

[0027] (2) impurity removal and drying: the cleaned tea tree leaves and young shoots are sterilized, after sterilization, the impurities are removed, and then dried until the water content does not exceed 12%;

[0028] (3) pulverizing: pulverizing the tea tree leaves and young shoots through step 2 to obtain powder;

[0029] (4) Add water to the powder in step 3, treat it with ultrasonic waves for 20-65 minutes, add an organic solvent 2-5 times its weight, and let it stand at 20°C for 1 hour to obtain a mixed solution;

[0030] (5) Put the mixed solution treated in step 4 into a steam distillation device to distill for steam extraction, the temperature during distillation ...

Embodiment 2

[0034] This embodiment has been further optimized on the basis of embodiment 1, specifically:

[0035] Further, in step 2, according to different particle size requirements, powders with different particle sizes are obtained through a 30-150 mesh sieve.

[0036] Further, the organic solvent described in step 4 is absolute ethanol or petroleum ether.

Embodiment 3

[0038] Step 1: Raw material collection: select fresh tea tree leaves and fresh young shoots, the ratio of tea tree leaves to young shoots is 3:1;

[0039] Step 2: Impurity removal and drying: clean tea tree leaves and young shoots are sterilized, after sterilization, impurities are removed, and then dried until the water content does not exceed 12%;

[0040] Step 3: pulverizing: pulverizing the tea tree leaves and young shoots through step 2 to obtain powder;

[0041] Step 4: The pulverized powder is irradiated with LED light: specifically, the light time is 15 minutes, the light intensity is 16lx, and the color temperature of the light is 5500K;

[0042] Step 5: add water to the powder in step 4, treat it with ultrasonic wave for 20minmin, add an organic solvent 4 times its weight, and let it stand at 20°C for 1h to obtain a mixed solution;

[0043] Step 6: put the mixed liquid treated in step 5 into a steam distillation device for steam extraction, the temperature during di...
