Embodiment 1

[0044] Example 1 An extraction process of the volatile oil of Artemisia sylvestris includes the following steps:

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

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

[0047] (3) After the distillate is naturally cooled, dried with anhydrous sodium sulfate in a weight ratio of 1:6 and filtered to remove the solids, 5.4 ml of Artemisia serrata volatile oil is obtained, and the yield ...

Embodiment 2

[0048] Example 2 An extraction process of the volatile oil of Artemisia serrata includes the following steps:

[0049] (1) Remove 3 kg of fresh Artemisia sylvestris from the ground, chop it to 0.5-3cm, put it in a volatile oil extractor, and soak it with 20 times its weight in water for 2 hours to fully infiltrate the broken pieces of Artemisia sylvestris.

[0050] (2) Move the volatile oil extractor containing the pieces of Artemisia sylvestris and its soaking liquid in step (1) to the 98-1-B electronic constant temperature electric heating mantle for steam distillation, the distillation temperature is 120 ℃, and the distillation time For 15h, collect distillate every 1h.

[0051] (3) After the distillate is naturally cooled, dried with anhydrous sodium sulfate in a weight ratio of 1:10 and filtered to remove the solids, 8.9 ml of Artemisia serrata volatile oil is obtained, and the yield is 0.30%.

Embodiment 3

[0052] Example 3 An extraction process for the volatile oil of Artemisia serrata, including the following steps:

[0053] (1) Remove 2 kg of fresh Artemisia sylvestris and chop it to 0.5-3cm, put it in a volatile oil extractor and soak it with 15 times its weight in water for 7 hours to fully infiltrate the pieces of Artemisia sylvestris.

[0054] (2) Move the volatile oil extractor containing the pieces of Artemisia sylvestris and its soaking liquid in step (1) to the 98-1-B electronic constant temperature electric heating mantle for steam distillation, the distillation temperature is 100 ℃, and the distillation time For 9h, collect the distillate every 1h.

[0055] (3) After the distillate is naturally cooled, dried with anhydrous sodium sulfate in a weight ratio of 1:3 and filtered to remove the solids, 6.4 ml of Artemisia serrata volatile oil is obtained, and the yield is 0.32%.

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 capable of 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 angustifolia, as well as its extraction process and application. Background technique [0002] Artemisia rutifolia (Artemisia rutifolia) is a semi-shrubby herbaceous plant of the Compositae genus Artemisia, born in mountain basins (deserts), terrace gullies, at an altitude of 3,200-3,800 meters, distributed in Qinghai, Xinjiang, Tibet; Central Asia and Iran , Afghanistan, Pakistan, and Russia are also distributed. Artemisia sylvestris is rich in resources in Qinghai. It generally grows in clusters, and its stems and leaves exude a strong aroma. Terpenoids are more common in volatile oil components, including monoterpenes and sesquiterpenes. In addition, they still contain small molecular aliphatic compounds and small molecular aromatic compounds. Among them, oxygen-containing derivatives of terpenoids or aromatic compounds give off a special aromatic smell, and h...
