Embodiment 1

[0027] A method for extracting the volatile oil of Tassel Flowers is:

[0028] Step 1. Take tassel flowers in May, dry them, and set aside;

[0029] Step 2: Take 100g of tassel flowers and 2g of sodium chloride according to the weight fraction ratio, add tassel flowers to a 10-liter distillation reactor, then add distilled water to make the surface of tassel flowers moist, then add sodium chloride, mix well, Add distilled water into the 10-liter steam generator, the amount of distilled water accounts for 2 / 3 of the volume of the steam generator, heat to 100°C, steam enters the distillation reactor through the conduit, and distill for 4 hours to remove tassel flower residue. Obtain the extract and set aside;

[0030] Step 3, take 50 g of hexane solvent and 50 g of extract according to the weight fraction ratio, add the extract to the hexane solvent, mix well, and extract to obtain extract I, which is set aside;

[0031] Step 4, according to the method of step 3, repeat the ex...

Embodiment 2

[0035] A method for extracting the volatile oil of Tassel Flowers is:

[0036] Step 1. Take tassel flowers in May, dry them, and set aside;

[0037] Step 2: Take 100g of tassel flowers and 3g of sodium chloride according to the weight fraction ratio, add tassel flowers to a 10-liter distillation reactor, then add distilled water to make the surface of tassel flowers moist, then add sodium chloride, mix well, Add distilled water into a 10-liter steam generator, the amount of distilled water accounts for 2 / 3 of the volume of the steam generator, heat to 100°C, steam enters the distillation reactor through a conduit, and distill for 6 hours to remove tassel flower residues, Obtain the extract and set aside;

[0038] Step 3, take 65g of hexane solvent and 65g of extract according to the weight fraction ratio, add the extract to the hexane solvent, mix evenly, and extract to obtain extract I, set aside;

[0039] Step 4, according to the method of step 3, repeat the extraction twi...

Embodiment 3

[0043] A method for extracting the volatile oil of Tassel Flowers is:

[0044] Step 1. Take the tassel flowers in May, wash the soil on the surface of the tassel flowers with water, dry them, and set aside;

[0045] Step 2: Take 100g of tassel flowers and 5g of sodium chloride according to the weight fraction ratio, add tassel flowers to a 10-liter distillation reactor, then add distilled water to make the surface of tassel flowers moist, then add sodium chloride, mix well, Add distilled water into the 10-liter steam generator, the amount of distilled water accounts for 2 / 3 of the volume of the steam generator, heat to 100°C, steam enters the distillation reactor through the conduit, and distill for 8 hours to remove tassel flower residues, Obtain the extract and set aside;

[0046] Step 3, take 80g of hexane solvent and 80g of extract according to the weight fraction ratio, add the extract to the hexane solvent, mix well, extract to obtain extract I, and set aside;

Abstract

The invention discloses a method for extracting Chinese fringe flower volatile oil, in particular to a method for extracting the Chinese fringe flower volatile oil from volatile oil which is prepared from Chinese fringe flowers by using distillation and extraction methods and contains 60 kinds of chemical components. The method comprises the steps of: distilling the Chinese fringe flowers and sodium chloride to obtain an extracted solution, adding the extracted solution to a hexane solvent for extraction, mixing the extracted solutions obtained in all extraction processes to form a mixture, adding anhydrous magnesium sulfate into the mixture, standing until blocky magnesium sulfate is formed, and filtering and evaporating to remove the hexane solvent contained in the filtrate to obtain a product. The method disclosed by the invention is used for extracting the Chinese fringe flower volatile oil from the Chinese fringe flowers, the medicinal and floral components contained in the plantChinese fringe tree are demonstrated, the medicinal values of the Chinese fringe flowers and the fact that the Chinese fringe flowers can be developed as perfumes and essences are illustrated, and the economic and social benefits of the plant Chinese fringe tree are increased.

Description

technical field [0001] The invention relates to a method for extracting volatile oil, in particular to a method for extracting volatile oil from tassel flower. Background technique [0002] Tassel plants (Oleaceae, Tasseliaceae, Chionanthus retusus, Lindl. et Paxt), is a unique precious tree species in my country, and a national second-class protected plant. Tassel tree is a deciduous tree, an excellent ornamental tree species, and young trees can be used as rootstocks for grafting sweet-scented osmanthus. It blooms in late spring, and the flowering period lasts for about half a month. The white flowers are fragrant at the top, and the slender corolla blooms upwards with four deep lobes, just like the tassels of ancient ladies' clothing, hence the name. Dried flowers and young leaves can be used as a substitute for tea and made as a beverage with a fragrant taste; the fruit has a large oil content and can be squeezed for aromatic oil for industrial use. Tassel is also k...
