The antimalarial activities of these compounds are in the range of EC5010-4-10-6M, with the novel endoperoxide sesquiterpene, 10,12-peroxycalamenene, exhibiting the strongest effect at EC502.33 × 10-6M. © 1995.Mahidol UniversityAgricultural and Biological SciencesBiochemistry, Genetics and Molecular BiologyChemistryPharmacology, Toxicology and PharmaceuticsArticleSCOPUS10.1016/0031-9422(95)00260-E
