Tu Youyou found out? Artemisinin? Only by studying hard can you win the Nobel Prize in the future. Artemisinin is a colorless crystal, which would not have been discovered if people were not actively looking for effective methods to study malaria. There are many ancient prescriptions in our country to deal with the diseases at that time, and some ancient books contain amazing wisdom. There were more than 100 diseases in the "fifty-two wards" of pre-Qin medical skill. Although some of them are incomplete, half of them are methods and soups that are not found in Shennong's Herbal Classic. It accounts for a large proportion of surgical diseases, but scientists were inspired by this book and found that Artemisia annua could treat malaria at that time.
Tu Youyou continuously purified and tested artemisinin in the experiment. Although artemisinin is easily soluble in chloroform, ethyl acetate and benzene, it is almost insoluble in water, so the refining process is very easily affected. It took Tu Youyou so many years to successfully extract artemisinin.
Artemisinin has many functions, such as treating embryo toxicity, anti-fungal, cardiovascular and immune regulation. The original function of artemisinin is naturally to fight malaria. After artemisinin is used, it can not only kill insects, but also make some insects unable to suck blood without obvious side effects. Later, artemisinin was found to be widely used. Artemisinin and its derivatives are so sad that they can not only control the mitogen of T lymphocytes well, but also have a direct inhibitory effect on B lymphocytes without increasing cytotoxicity. Artemisinin has anti-inflammatory effect, so it can inhibit a variety of inflammatory factors and treat pulmonary hypertension by relaxing blood vessels.
Artemisinin can also treat embryo toxicity, antifungal, cardiovascular effects, immune regulation and other effects. Tu Youyou is the first person in China to win the Nobel Prize in Natural Science, which deserves our pride.
