ISOLASI DAN IDENTIFIKASI ARTEMISININ DARI HERBA Artemisia annua L .

Abstract


Abstract. Malaria is still a major problem in Indonesia, because mortality in patients with severe malaria remains high. Many cases are occurs in endemic areas (e.g. Papua,Kalimantan, Bali and Sulawesi). Chloroquin is the most common antimalarial drug which is widely used since 1934. Plasmodium falciparum resistant to chloroquine was reported in some countries (e.g. Thailand, Vietnam, Indonesia, and Bangladesh). To delay the development of resistance, WHO recommended antimalarial combination therapy. Artemisinin and its derivatives (artesunate, artemether, dihydroartemisin) produce rapid clearance of parasitemia and rapid resolution of symptoms compare with chloroquine. Artemisinin is obtained from Artemisia annua L. Even though there are some research produced a chemical synthetic of artemisinin, but it is not efficient and notstable. Our purposes are to conduct a preliminary research to obtain a method of isolation and identification of artemisinin which is the first step to develop a raw material of artemisinin as antimalarial drug in Indonesia.

The first step of isolation is extraction from herb Artemisia annua L with n-hexane thatproduced n-hexane extract, this process is well-known as soxhletation. The second step isidentification of chemical substances from n-hexane extract. The third step is to obtain isolate from n-hexane extract by fractionation with acetonitril and separation with column chromatography. The last step is chemical and physical identification of isolateby TLC (Thin Layer (Chromatography) and FT-IR.

The result from n-hexane extract measurement is 4.33 % and from acetonitril fraction is2. 40 %. Chemical identification of n-hexan extract found there are terpenoid, phenol, flavonoid, fatty acid, atsiri oil and saponin. Organoleptic identification of isolate is white crystal, monosubstrate, odorless and bitter. Identification of isolate with TLC and FT-IR confirmed that the isolate is artemisinin.

Keywords: artemisinin, Artemisia annua L, FT-IR and TLC.
