Problems solved by technology

[0005] At present, many eucalyptus oil extraction processes use extraction methods to extract high-purity eucalyptus oil, but this method is cumbersome to operate and the equipment is relatively expensive, which makes the extraction cost too high
Guangxi has abundant fast-growing eucalyptus resources locally. Fast-growing eucalyptus itself has certain differences in structure and composition from ordinary eucalyptus due to its rapid growth. Therefore, no domestic techniques and methods for extracting eucalyptus oil from fast-growing eucalyptus have been found.

Embodiment 1

[0023] The extraction method of fast-growing eucalyptus oil comprises the following steps:

[0024] (1) Break the fast-growing eucalyptus bark and leaves through a pulverizer;

[0025] (2) Put the broken fast-growing eucalyptus bark and leaves into the pot, add water with a weight ratio of 1:0.5 and boil for 15 minutes to obtain eucalyptus water;

[0026] (3) Add Sapindus sapinsia fruit extract with a weight ratio of 1:0.5 to the naturally cooled eucalyptus water and stir for 5 minutes. After a layer of eucalyptus oil is formed on the surface of the eucalyptus water, separate the eucalyptus oil on the surface from the eucalyptus water Separately put into containers for later use;

[0027] (4) Add 0.1% sucrose ester to the separated eucalyptus water, mix and stir for 5 minutes, pour the mixed solution into an evaporating dish and evaporate for 30-60 minutes to obtain eucalyptus oil, and combine the obtained eucalyptus oil with the step ( 3) The obtained eucalyptus oil is mixe...

Embodiment 2

[0033] The extraction method of fast-growing eucalyptus oil comprises the following steps:

[0034] (1) Break the fast-growing eucalyptus bark and leaves through a pulverizer;

[0035] (2) Put the broken fast-growing eucalyptus bark and leaves into the pot, add water with a ratio of parts by weight of 1:0.5 and boil for 20 minutes to obtain eucalyptus water;

[0036] (3) Add Sapindus sapinsia fruit extract with a weight ratio of 1:0.5 to the naturally cooled eucalyptus water and stir for 8 minutes. After a layer of eucalyptus oil is formed on the surface of the eucalyptus water, separate the eucalyptus oil on the surface from the eucalyptus water Separately put into containers for later use;

Abstract

The invention provides an extraction method for fast-growing eucalyptus oil. The extraction method for the fast-growing eucalyptus oil comprises the following steps that fast-growing eucalyptus barks and leaves are smashed and then boiled into eucalyptus water after water is added; a soap nut extracting solution is added for stirring firstly, and separating is conducted after a layer of oily substances are formed on the surface; sucrose ester is added into the remaining eucalyptus water for dissolution of effective components of the remaining eucalyptus oil; and after complete dissolution, the fast-growing eucalyptus oil is obtained from a solution through an evaporating dish. The prepared fast-growing eucalyptus oil can be applied to the field of preparation of car bactericide, repellent liquid, dissolved medicines for cold and the like.

Description

technical field [0001] The invention relates to the field of plant essential oil extraction, in particular to a method for extracting fast-growing eucalyptus oil. Background technique [0002] Fast-growing eucalyptus is one of the three famous fast-growing tree species in the world, and it is also one of the most valuable hard materials of broad-leaved trees in the world. Several tall and fast-growing trees native to the tropical rainforest in northeastern Australia are collectively referred to. There are more than 1,000 species of eucalyptus in the world. Usually, the main cutting is 6-8 years, and once planted, 2-3 times of harvesting, it is a short-cycle industry for cultivation It is one of the best tree species for raw material forest, and it is also an excellent tree species for greening around and coastal protection forest. Since 2000, fast-growing eucalyptus has been widely planted in Guangxi. At that time, under the constraints of the international market, my coun...
