Character deeds;
20 15 12 10 Tu Youyou won the nobel prize in medicine for his pioneering separation of artemisinin from Chinese herbal medicines and its application in malaria treatment. This is the first time that China won the Nobel Prize for scientific research. From 65438 to 0968, the Institute of Traditional Chinese Medicine began to study antimalarial drugs, with 39-year-old Tu Youyou as the project leader.
After two years of research object screening, and inspired by China ancient Pharmacopoeia "Elbow Backup Emergency Prescription", the project team focused on Artemisia annua. 197 1 year, after 190 failures, the project team finally successfully extracted artemisinin through low-temperature extraction and cold soaking with ether, and in subsequent repeated experiments, it was concluded that the inhibition rate of artemisinin on malaria reached 100%.
In the absence of advanced experimental equipment and difficult scientific research conditions, Tu Youyou led the team to overcome difficulties, never flinched in the face of failure, and finally successfully completed the scientific research task. Since artemisinin was invented 44 years ago, * * * has saved more than 6 million people from malaria. In the future, Tu Youyou hopes that artemisinin can be applied to more places and bring good news to more people through research.
Extended data;
Tu Youyou's scientific contribution is the discovery of artemisinin. Inspired by the ancient books of Chinese medicine, she changed the traditional extraction process of Artemisia annua and created a method for extracting the antimalarial effective parts of Artemisia annua at low temperature, which became a key breakthrough in the discovery of artemisinin. The antimalarial effective parts of Artemisia annua were extracted for the first time, and the inhibition rate was 100%.
And made a report at the national "523" conference, which led to the anti-malaria research of Artemisia annua extract in China. For the first time, she and her team isolated artemisinin from the anti-malaria effective part of Artemisia annua.
The clinical trials of "ether in" and artemisinin monomer were first carried out, which confirmed their clinical effectiveness in treating malaria. The chemical structure of artemisinin was confirmed with the cooperative unit * *, which provided conditions for the development of its derivatives. She and her team developed artemisinin, which is the first new drug since China implemented the new drug approval method.
