Embodiment 1

[0042] Taking the artemisia annua wax oil produced in the process of extracting artemisinin from Guangxi Xiancaotang Pharmaceutical Co., Ltd. as the raw material to be refined, 10 g of the artemisia annua wax oil was mixed with 60 mL of acetone, and deoiling was carried out under stirring conditions of 3000 r / min ( The temperature of deoiling treatment is 25°C, and the time is 30min; the number of times of deoiling treatment is 2), and the obtained system is subjected to centrifugal separation to obtain oil-containing solvent (after recovery, further distillation and separation can be obtained to obtain fatty oil and solvent) and solvent-containing wax , vacuum-drying the solvent-containing wax to constant weight at 50° C. to obtain deoiled artemisia wax (the deoiling rate is 67.5%);

[0043] Mix 10 g of the deoiled artemisia wax with 30 mL of water, heat to 90° C. to dissolve the deoiled artemisia wax in the water, then add 10 mL of hydrochloric acid with a mass concentration ...

Embodiment 2

[0049] The refined artemisia wax was prepared according to the method of Example 1, except that in the deoiling treatment step, the deoiling reagent was ethyl acetate; wherein, the deoiling rate was 40%.

Embodiment 3

[0051] The refined artemisia wax was prepared according to the method of Example 1, except that in the deoiling treatment step, the deoiling agent was n-heptane; wherein, the deoiling rate was 50%.

Abstract

The invention relates to the technical field of vegetable wax refining, particularly to a refining method of artemisia apiacea wax. The method provided by the invention comprises the following steps:mixing artemisia apiacea wax oil with a deoiling reagent, and then carrying out deoiling treatment to obtain deoiled artemisia apiacea wax; mixing the deoiled artemisia apiacea wax, water and hydrochloric acid, and performing ash removal treatment to obtain ash-removed artemisia apiacea wax; and mixing the ash-removed artemisia apiacea wax with a decolorizing agent, and then carrying out decolorizing treatment to obtain refined artemisia apiacea wax. According to the method, the artemisia apiacea wax oil is subjected to deoiling treatment with the deoiling reagent, so that substances such as fatty lipids, resin lipids and the like in the artemisia apiacea wax oil can be effectively removed; then the artemisia apiacea wax oil is subjected to ash removal treatment by utilizing the hydrochloric acid hydration method, so that ash in the artemisia apiacea wax oil can be effectively removed; and finally the deashed artemisia apiacea wax is subjected to decolorization treatment, so that the deep processing value of the obtained refined artemisia apiacea wax is improved.

Description

technical field [0001] The invention relates to the technical field of vegetable wax refining, in particular to a refining method of Artemisia annua wax. Background technique [0002] Artemisinin has been used in malaria control with excellent results. Artemisia annua for artemisinin extraction is distributed all over the country and can grow in hillsides, wasteland, forest margins and other areas. Artemisia annua wax oil (also known as crude artemisia wax) is the primary purification residue of artemisinin extracted from Artemisia annua L. Organic chemical components such as wax have high research value. So far, 1 ton of artemisinin can produce about five tons of artemisinin wax oil. According to preliminary estimates, at the same time as artemisinin production, my country produces about 1,000 tons of artemisinin wax oil every year. However, the artemisinin industry has not carried out systematic research on artemisinin wax oil, nor has it conducted comprehensive develop...
