Background: WHO recommends that malaria drug should be used with essential elements which are derivatives of artemisinin (ART) for treatment phase and limit the development of parasite (MIC). Objective: To assess in vitro effect of artemisinin powder and 10 alpha- trifluoro methyl hydroartemisinin (TEMHA) in powder and tablet form to P.falciparum. Subject and Method: 48h in vitro test of Phuc Nguyen Dinh was applied to this study. Results and Conclusions: The results showed that: for T996, IC50 values of ART, 10 alpha- TEMHA powder and 10 alpha- TEMHA pill were as follows: 37.8; 16.4 and 17.6 nM/L, respectively. For K1, IC50 values of ART, 10 alpha- TEMHA powder and 10 alpha- TEMHA pill were: 22.8; 11.4 and 12.2 nM/L, respectively. MIC values of artemisinin powder, 10 alpha- TEMHA powder and pill for T996 were as follows: 100; 40 and 40nM/L, respectively. For K1, MIC values of ART, 10 alpha- TEMHA powder and pill are: 76; 24; 32 nM/L, respectively.
