Malaria is currently one of the most important causes of mortality in developing countries. High resistance to available antimalarial drugs has been reported frequently, thus it is crucial to focus on the discovery of new antimalarial drugs. Artemisinin, an effective antimalarial medication, is isolated from various Artemisia species. To identify the Artemisia species producing high quantity of artemisinin, eight species of Artemisia were screened with the genetic sequence characterized amplified region (SCAR) marker for higher quantity of artemisinin. The DNA band corresponding to SCAR marker was cloned into pGEM®-T Easy vector and sequenced. The content of artemisinin in tested species was also measured using high-performance liquid chromatography (HPLC) assay. The primers designed for high-artemisinin SCAR marker could amplify a specific band of approximately 1000 bp which was present in two Artemisia annua and Artemisia absinthium species. These SCAR marker sequences for two selected species were submitted into the GenBank databases under KC337116 and KC465952 accession numbers. HPLC analysis indicated that two selected Artemisia species, genetically recognized as high-artemisinin yielding plants, had higher artemisinin content in comparison to other examined species. Therefore, in this study, we propose developed SCAR marker as a complementary tool for confidently detection of high-artemisinin content in Artemisia species.
