In this paper, the initial publication of the chemical structure of artemisinin on Chinese Science Bulletin (1977), as well as the disclosure of its antimalarial efficacy and R&D process on Guangming Daily (1978) are documented, and both events have revealed the contribution of Tu Youyou and the Institute of Chinese Medicine of Academy of Traditional Chinese Medicine in the identification and structure determination of artemisinin. The author argues that the disclosure of the particular details in artemisinin's antimalarial research actually did not bring any disadvantages to the invention patent application of artemisinin; instead, it has played a certain role to make Tu Youyou, a 2015 Nobel Prize winner in Physiology or Medicine.
