1,  Product title:   Artemisinin 

2,  Product Description:

Artemisinin is a sesquiterpenoid lactone drug with peroxy group extracted from the stem and leaves of Artemisia annua. The effect of the drug on the ultrastructure of rat plasmodium in red phase is mainly the change of plasmodium membrane structure. The drug first acts on food vesicle, membrane, mitochondria and endoplasmic reticulum, and also has some effect on nuclear chromatin. It is suggested that artemisinin interferes with the function of mitochondria. It may be that artemisinin acts on the food vesicle, thus blocking the earliest stage of nutrient intake, causing the malaria parasite to quickly starve of amino acids, rapidly form autophagy vesicles, and continuously expel the parasite, causing the malaria parasite to lose a large number of cytoplasm and die. The uptake of tritium-labeled isoleucine by P. falciparum cultured in vitro also suggested that its initial action might be inhibition of protozoan protein synthesis.青蒿素是从植物黄花蒿茎叶中提取的有过氧

4,  In vivo studies:

Artemisinin (50,100 or 200mg/kg B.t/day, Po) prevents isoflurane-induced impairment of working memory, as observed in the T-maze test. Artemisinin enhances spatial navigation and memory in isoflurane exposed rats. Rats treated with artemisinin showed significantly better performance than those treated with isoflurane alone.

eat
Never feed anything through the mouth to an unconscious person. Rinse your mouth with water.

6,  Pharmacological effects:

1. Artemisinin is a sesquiterpene lactone drug with peroxygen group extracted from Artemisia annua, a traditional Chinese medicine. It is a highly effective, quick - acting, low - toxicity antimalarial drug. It has a strong and rapid killing effect on Plasmodium erythrocyte phase, and can quickly control the clinical outbreak and symptoms.

2. The mechanism of artemisinin is still not clear. It mainly interferes with the mitochondrial function of plasmodium. Artemisia annua Qin changes the membrane structure of Plasmodium by affecting the ultrastructure of the erythrocyte phase. Due to the action of food vesicle, the nutrient intake of Plasmodium is blocked. When the Plasmodium loses a large amount of cytoplasm and nutrients, and cannot be replenished, it soon dies.

3. Its mode of action is to produce unstable organic free radicals and/or other electronophilic intermediaries through the internal peroxide (dioxygen) bridge mediated by the free iron produced after the decomposition of hemoglobin, and then form covalent admixture with the plasmodium protein, causing the plasmodium to die. The antimalarial activity of artemether is 6 times greater than that of artemisinin.

7,  pharmacokinetics:

After absorption, the product is distributed in the tissue, with more intestinal, liver and kidney content. This product is a fat soluble substance that can easily penetrate the blood-brain barrier into the brain tissue. Fast metabolism in the body, mainly from the kidney and intestinal tract excretion, 24 hours can be excreted 84%, 72 hours only a small amount of residual. Due to the rapid metabolism and excretion, and the short maintenance time of effective blood drug concentration, it is not conducive to the complete killing of Plasmodium, so the reburning rate is high.
