Embodiment 1

[0044] Using the Artemisia annua wax oil produced during the extraction of artemisinin by Guangxi Xiancaotang Pharmaceutical Co., Ltd. as the raw material to be refined, mix 10g of the Artemisia annua wax oil with 30mL of water, and heat to 85°C to dissolve the Artemisia annua wax oil in the water , and then add 10mL of hydrochloric acid with a mass concentration of 36.5%, carry out ash removal treatment at 4000r / min and 90°C for 60min, carry out suction filtration after the obtained system is cooled, and wash the obtained filter cake with boiling water until it is neutral. Under the condition of ℃, vacuum dry to constant weight to obtain deashed Artemisia annua wax (ash removal rate is 94.27%, ash content is 0.30%);

[0045] Mix 10 g of the deashed Artemisia annua wax with 40 mL of methanol, and carry out extraction treatment under the condition of 1000 W ultrasonic power (the temperature of the extraction treatment is 35 ° C, the time is 40 min; the number of times of extract...

Embodiment 2～9

[0053] The refined Artemisia annua wax was prepared according to the method of Example 1, the difference being the relevant parameters of the ash removal treatment step, as shown in Table 1.

[0054] Relevant parameters of ash removal treatment steps in Table 1 embodiment 1~9

[0055]

[0056] As can be seen from Table 1, the method provided by the invention is used to carry out deashing treatment on Artemisia annua wax oil, the ash removal rate is more than 82%, and the ash content in the obtained deashed Artemisia annua wax is between 0.08~0.30%, which has better ash removal effect.

Embodiment 10

[0058] The refined Artemisia annua wax was prepared according to the method of Example 1, except that in the extraction treatment step, the extraction reagent was 95 wt% ethanol aqueous solution; wherein, the yield of the obtained defatted Artemisia annua wax was 20.53%.

Abstract

The invention relates to the technical field of vegetable wax refining, particularly to a refining method of artemisia apiacea wax. According to the invention, ash removal treatment is conducted on artemisia apiacea wax oil through a hydrochloric acid hydration method, so that ash in the artemisia apiacea wax oil can be effectively removed, and it is guaranteed that follow-up extraction treatmentis smoothly conducted; the ash-removed artemisia apiacea wax is extracted, and the obtained solvent-containing wax is distillated, so that substances such as fat lipids, resin lipids and the like in the ash-removed artemisia apiacea wax can be fully removed, a solvent in the solvent-containing wax is removed, and the artemisia apiacea wax with relatively high purity can be obtained; finally the degreased artemisia apiacea wax is subjected to decoloration treatment, so that the deep processing value of the refined artemisia apiacea wax is improved; and results of the embodiment show that when the method provided by the invention is used for refining the artemisia apiacea wax oil, the obtained refined artemisia apiacea wax is high in yield and high in whiteness.

Description

technical field [0001] The invention relates to the technical field of vegetable wax refining, in particular to a method for refining Artemisia annua wax. Background technique [0002] Artemisinin has been used in the prevention and treatment of malaria with excellent results. Artemisia annua used for artemisinin extraction is distributed all over the country and can grow in hillsides, wastelands, forest margins and other areas. Artemisia annua wax oil (also known as Artemisia annua crude product) is the initial purification residue of artemisinin extracted from Artemisia annua with organic solvents. It has a yellow-brown color, fragrant smell, and is in a semi-solid state. Wax and other organic chemical components have high research value. So far, 1 ton of artemisinin can produce about five tons of artemisinin wax oil. According to preliminary estimates, while producing artemisinin, my country produces about 1,000 tons of artemisinin wax oil every year. However, the arte...
