Embodiment 1

[0025] A method for extracting and processing Artemisia annua essential oil, comprising the following steps:

[0026] A. Harvest the branches of Artemisia annua in sunny days and cut them into 10.5cm-long sections and spread them on the ground for 6 hours. During the spreading process, the thickness of the flower layer should not exceed 20cm;

[0027] B. After adding deionized water into the Artemisia oleifera branch section through spreading, drop into the distillation pot, the amount of deionized water added is 3 times of the quality of the Artemisia oleifera branch section through spreading, heat to 80 with direct steam ℃, and then use indirect steam to heat to a slight boil, and the condensate enters the oil-water separator for oil-water separation. Firstly, the condensate temperature is 35°C and the indirect steam volume is 200L / hour for 1 hour; then the condensate temperature is Carry out 1 hour at 35°C and an indirect steam volume of 300L / hour, collect the Artemisia ann...

Embodiment 2

[0033] A method for extracting and processing Artemisia annua essential oil, comprising the following steps:

[0034] A. Harvest the branches of Artemisia annua on a sunny day, cut them into 9.5cm-long sections and spread them on the ground for 3 hours. During the spreading process, the thickness of the flower layer should not exceed 20cm;

[0035] B. After adding deionized water into the Artemisia oleifera branch section through spreading, drop into the distillation pot, the amount of deionized water added is 3 times of the quality of the Artemisia oleifera branch section through spreading, heat to 80 with direct steam ℃, and then use indirect steam to heat to a slight boil, and the condensate enters the oil-water separator for oil-water separation. First, the condensate temperature is 30°C and the indirect steam volume is 200L / hour for 1 hour; then the condensate temperature is Carry out 1 hour under the conditions of 40°C and indirect steam volume of 300L / hour, collect the ...

Embodiment 3

[0041] A method for extracting and processing Artemisia annua essential oil, comprising the following steps:

[0042] A. Harvest Artemisia annua branches on sunny days, cut them into 10cm-long sections and spread them on the ground for 4.5 hours. During the spreading process, the thickness of the flower layer should not exceed 20cm;

[0043] B. After adding deionized water into the Artemisia oleifera branch section through spreading, drop into the distillation pot, the amount of deionized water added is 3 times of the quality of the Artemisia oleifera branch section through spreading, heat to 80 with direct steam ℃, and then use indirect steam to heat to a slight boil, and the condensate enters the oil-water separator for oil-water separation. First, the condensate temperature is 32°C and the indirect steam volume is 200L / hour for 1 hour; then the condensate temperature is Carry out 1 hour under the conditions of 37°C and indirect steam volume of 300L / hour, collect the Artemis...

Abstract

The invention discloses an extraction and treatment method for essential oil of Acroptilon repens. The method comprises the steps of: harvesting above-ground branches of Acroptilon repens plants on sunny days, then performing cutting, and spreading the cut branches on the ground for 3-6h; adding deionized water, then putting the substances into distillation pot, performing direct steam heating to 80DEG C, then switching to indirect steam heating to slight boiling, and conducting oil-water separation on the condensate liquid to obtain primary essential oil of Acroptilon repens; adding the distilled solution obtained by primary distillation separation of essential oil of Acroptilon repens into the distillation pot again, and conducting indirect steam heating to obtain secondary essential oil of Acroptilon repens; mixing the primary essential oil of Acroptilon repens with the secondary essential oil of Acroptilon repens evenly in a mass ratio of 1.5:1 to obtain standard essential oil of Acroptilon repens, adding anhydrous sodium sulfate and activated carbon in order, performing stirring at room temperature for 48h, and conducting filtering to obtain dehydrated and decolored standard essential oil of Acroptilon repens; bottling the dehydrated and decolored standard essential oil of Acroptilon repens, performing sealing, and then conducting irradiation in the sun for 7 days. The essential oil of Acroptilon repens obtained by the method has good quality.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for extracting and treating Artemisia annua essential oil. Background technique [0002] Artemisia annua essential oil is the volatile oil extracted from the flowers or branches of Artemisia annua, a plant of Verbenaceae genus Artemisia annua. It has a special aroma and a slightly pungent taste. Artemisia annua essential oil contains more than 30 kinds of ingredients, the main ingredients are p-cymene, α-terpinene, isocarcinol and so on. [0003] The quality of Artemisia annua extracted by the prior art is poor, and the contents of iso-ascaridin, p-cymene, α-terpinene, ascaridin and limonene are relatively low. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a method for extracting and processing Artemisia annua essential oil. [0005] To achieve the above object, the technical scheme adopted in the present inven...
