Пероксиды – новый класс соединений для разработки антипаразитарных препаратов 3 About 300 -400 millions of peoples suffer from malaria and approximately 1 million of peoples dies each year. Artemisinin is very effective against malaria, but its cost is high. Artemisinin or Qinghaosu is the active constituent of the herb sweet wormwood (Artemisia annua). Good quality Artemisia annua contains 0. 3 -0. 5% of artemisinin. N. D. Zelinsky Institute of Organic Chemistry
