Artemisinin, a sesquiterpene lactone initially extracted from the medicinal plant Artemisia annua L., is a good antimalarial agent, rather for multi-drug resistant and cerebral malaria. in spite of the fact that, the focus of artemisinin within the plant is particularly low. as the chemical synthesis of artemisinin is advanced and never economically possible in view of the terrible yield of the drug, the intact plant continues to be the one achievable resource of artemisinin construction. consequently, it's important to extend the focus of artemisinin in A. annua to lessen the price of artemisinin dependent antimalarial medications. Plant scientists have targeted their efforts on A. annua for a better artemisinin crop yield. With the current quantity, we're bringing jointly the learn that is being performed in this plant during the global and destiny chances for scientists and researchers who are looking to paintings on it.
