General description

Artemisinin is extracted from sweet wormwood (Artemisia annua). It has anticancer, antiprotozoal and antiviral activities. Artemisinin is associated with brainstem encephalopathy.


Artemisinin has been used:
  • in drug susceptibility assays
  • as a standard for its quantification from artemisinin from hairy roots
  • to check cell viability using 3-(4, 5-dimethylthiazol-2yl)-2,5-diphenyl tetrazolium bromide (MTT) assay
  • as an antimalarial agent to investigate the role of autophagy-related (ATG) genes throughout the P. falciparum asexual and sexual blood stages


100 mg in glass bottle

Biochem/physiol Actions

Artemisinin (Qinghaosu), a sesquiterpene lactone, is a highly active anti-malarial (falciparum malaria) drug. Artemisinin is also an anthelmintic (parasitic worm) effective against the blood fluke, schistosomiasis.
