Embodiment Construction

[0026] The purpose of the present invention can be achieved through the following technical solutions:

[0027] A method for extracting Chinese fir essential oil, the method comprising the following steps:

[0028] Step 1. After peeling off the roots and branches of the fresh Zhongshan fir, take the Zhongshan fir leaves, and gently wash the Zhongshan fir leaves with clean water;

[0029] Step 2, put the washed Zhongshan fir leaves into the desiccator, blow and dry at low temperature to obtain dried Zhongshan fir leaves;

[0030] Step 3: Immerse the Zhongshan fir leaves in liquid nitrogen, freeze-dry them quickly, then take them out, put them into a ball mill and grind them into solid particles;

[0031] Step 4, put the above particles into a supercritical carbon dioxide extraction device for extraction, and pass through the primary separation kettle and the secondary separation kettle in turn to obtain the primary extract of Zhongshan fir and the secondary extract of Zhongsha...

Abstract

The invention discloses an extraction methodof taxodium zhongshanense essential oil. The method comprises the following steps: freezing, ball-milling and crushing taxodium Zhongshanense leaves, and carrying out supercritical carbon dioxide extraction separation to obtain the taxodium Zhongshanense essential oil and byproducts of taxodium Zhongshanense heavy oil and taxodium Zhongshanense wax; thesupercritical carbon dioxide extraction is carried out at a low temperature; and according to the method, the natural components of the taxodium zhongshanense essential oil can be effectively protected from being damaged through steam distillation, no chemical solvent is added, and the obtained taxodium zhongshanense essential oil is natural, free of pollution and pure and rich in smell, so that atechnical and product quality guarantee is provided for production of the taxodium zhongshanense essential oil and development of related products. The method has the characteristics that the naturalcomponents of the taxodium zhongshanense essential oil are effectively protected from being damaged, and no chemical solvent is added.

Description

technical field [0001] The invention relates to an extraction method of Zhongshan fir essential oil, in particular to an extraction method of Zhongshan fir essential oil which can effectively protect the natural components of Zhongshan fir essential oil from being destroyed and has no chemical solvent addition residue. Background technique [0002] Zhongshan fir belongs to the genus Taxus in the family Taxaceae. It is a general term for excellent clones obtained through cross breeding among three tree species: Taxus cypress, Pool fir and Mexican cypress. [0003] Zhongshan fir is a semi-evergreen tall tree with a conical to broad oval crown, dense leaves, straight trunk, fast-growing, salt-alkali-resistant, strong resistance to separation, less pests and diseases, excellent material, long green period, and good landscape effect, etc. advantage. Zhongshan fir not only has good ornamental value, but also is conducive to water conservation and soil and water conservation. It i...
