Embodiment 1

[0044] Embodiment 1 A kind of extraction process of volatile oil of Artemisia saponica, comprising the following steps:

[0045] (1) Remove impurities from the ground part of 2kg of fresh Artemisia fragrans, chop it to 0.5-3cm, put it into a volatile oil extractor produced by Shanghai Tongxin Biomedical Technology Co., Ltd., soak it in water 10 times its weight for 12 hours, Fully infiltrate the broken pieces of Artemisia fragrans.

[0046] (2) Move the volatile oil extractor containing Artemisia saponica fragments and its soaking solution in step (1) to the 98-1-B electronic constant temperature electric heating mantle produced by Tianjin Test Instrument Co., Ltd. for steaming Distillation, the distillation temperature is 80°C, the distillation time is 3h, and the distillate is collected every 1h.

[0047] (3) After the distillate was naturally cooled, it was dried with anhydrous sodium sulfate at a weight ratio of 1:6, and the solid was filtered off to obtain 5.4 ml of vola...

Embodiment 2

[0048] Embodiment 2 A kind of extraction process of the volatile oil of Artemisia saponica, comprising the following steps:

[0049] (1) After removing impurities and chopping 3kg of the above-ground part of fresh Artemisia oleifera into 0.5-3cm, put it into a volatile oil extractor and soak it in water 20 times its weight for 2 hours to fully infiltrate the fragments of Artemisia oleifera.

[0050] (2) Move the volatile oil extractor filled with pieces of Artemisia saponica and its soaking solution in step (1) to the 98-1-B electronic constant temperature electric heating mantle for steam distillation, the distillation temperature is 120°C, and the distillation time For 15h, the distillate was collected every 1h.

[0051] (3) After the distillate was naturally cooled, it was dried with anhydrous sodium sulfate at a weight ratio of 1:10 and the solid was filtered off to obtain 8.9 ml of volatile oil of Artemisia saponifolia with a yield of 0.30%.

Embodiment 3

[0052] Embodiment 3 A kind of extraction process of volatile oil of Artemisia saponica, comprising the following steps:

[0053] (1) After removing impurities and chopping 2kg of the above-ground part of fresh Artemisia oleifera into 0.5-3cm, put it into a volatile oil extractor, soak it in water 15 times its weight for 7 hours, so that the fragments of Artemisia oleifera are fully infiltrated.

Abstract

The invention relates to Artemisia rutifolia essential oil which is light yellow oily liquid with heavy fragrance and is soluble in alcohols and liposoluble solvents. The essential oil mainly comprises monoterpenes, sesquiterpenes and oxo-derivatives and comprises the following main components by mass percent: 15-20% of eucalyptol, 15-20% of camphor, 8-12% of menthenol-4, 5-10% of isobutyl ketone-2-yl-benzene, 3-5% of p-isobutylphenol, 3-6% of menthenol-8, 3-5% of thujone, 3-5% of phellandrene, 3-5% of 6-methyl-2-ethenyl-heptadienal, 2-4% of m-methoxy-anethole, 2-4% of careen-3 and 0.2-1% of beta-myrcene. Meanwhile, the invention also discloses a preparation method of the essential oil, which is characterized by high extraction ratio and simple process flow. With active components capableof expelling phlegm to stop cough and clearing and nourishing throat, the Artemisia rutifolia essential oil can be applied to treating pneumonia and faucitis.

Description

technical field [0001] The invention relates to a plant volatile oil, in particular to the volatile oil of Artemisia saponifolia, as well as its extraction process and application. Background technique [0002] Artemisia rutifolia (Artemisia rutifolia) is a semi-shrub herb of the genus Artemisia in the family Asteraceae. It grows in intermountain basins (deserts), terraces and gullies, at an altitude of 3200-3800 meters, and is distributed in Qinghai, Xinjiang, Tibet; Central Asia and Iran , Afghanistan, Pakistan, and Russia are also distributed. Artemisia annua has abundant resources in Qinghai. It usually grows in clusters, and its stems and leaves emit a strong aroma. Among the volatile oil components, terpenes are more common, including monoterpenes and sesquiterpenes, etc. In addition, they also contain small molecular aliphatic compounds and small molecular aromatic compounds. Among them, the oxygen-containing derivatives of terpenoids or aromatic compounds emit a sp...
