Problems solved by technology

Finally, Africa is the main malaria-endemic area, but the people in Africa generally have a low standard of living and cannot afford artemisinin, which is a relatively expensive antimalarial drug for them, which leads to an overestimation of the market capacity of artemisinin

Embodiment Construction

[0012] Below in conjunction with specific preferred embodiment the present invention will be further described

[0013] Step (1) Extract the volatile oil by steam distillation. Step (2) Use gas chromatography to analyze each chemical component in the volatile oil of artemisinin, and use the area normalization method to determine its relative content

[0014] Further preferably, in the step (1), about 100 g of artemisinin leftovers are weighed, placed in a round bottom flask, 500 ml of water is added, and the volatile oil is extracted by steam distillation. Use the steam distillation method to extract the volatile oil, use this method until the volatile oil in the container no longer increases, get the volatile oil and measure its quality.

[0015] Further preferably, in the step (2), each chemical component in the volatile oil of artemisinin is analyzed by gas chromatography, and its relative content is determined by the area normalization method.

Abstract

The invention discloses a method for extracting artemisinin essential oil from artemisinin leftovers. The method comprises the following steps: (1) extracting volatile oil by using a steam distillation method; and (2) analyzing each chemical component in the artemisinin volatile oil by adopting a gas chromatograph, and determining the relative content of the artemisinin volatile oil by utilizing an area normalization method. The artemisinin essential oil can be processed into an antibacterial, anti-inflammatory and analgesic medicine, can be prepared into an environmental insect repellant, and can also be used as a flavoring raw material for flavoring. The development of the artemisinin essential oil can increase the income of the artemisinin industry and promote the artemisinin industry to be more diversified.

Description

technical field [0001] The invention relates to the development of a by-industry of artemisinin, which improves the profit of the artemisinin industry and maintains the stable operation of the entire artemisinin industry. Background technique [0002] Artemisinin is an antimalarial drug extracted from the stems and leaves of the plant Artemisia annua. It was discovered by the famous scientist Tu Youyou, for which she won the Nobel Prize in Physiology. Artemisinin has a strong inhibitory and killing effect on malaria parasites, so it is widely used in the treatment of malaria. Due to the unique antimalarial properties of artemisinin and compound artemether's remarkable efficacy and resistance to drug resistance, it was included in the list of essential drugs by the World Health Organization (WHO) in 2004 and promoted to the world. Many merchants saw the large number of orders brought by the World Health Organization and began to grow Artemisia annua in large quantities, resu...
