Function:

1. With function of controlling of vivax malaria and falciparum malaria symptom, as

well as treatment of chloroquine-resistant strain of insect.

2. With function of oxidant. artemisinin is reduced by catalase,dithiothreitol and

alpha tocopherol.

3. With the function of antibacterial, artemisinin has anti-influenza virus effect.

4. With the function of anti-parasite, artemisinin on the role of anti-schistosomiasis

and leptospirosis.

Application:

1.Artesunate is an antimalarial agent. It is a water-soluble hemisuccinate derivative of dihydroartemisinin.

2.Artemisinin is a sesquiterpene lactone isolated from Artemisia annua, a herb that has traditionally been used in China for the treatment of malaria.

3.Artesunate and its active metabolite dihydroartemisinin are potent blood schizonticides, active against the ring stage of the parasite.

4.Artesunate is ideal for the treatment of severe malaria, including cerebral malaria. It is also active against chloroquine and mefloquine resistant strains of P. falciparum.
