| dc.description.abstract | Background and objectives: The plants of genus Artemisia (Asteraceae) have been conventionally used for prevention and medication of a number of ailments. In the present research, ten extracts with different polarities from aerial parts of two Artemisia species, A. kopetdaghensis and A. turcomanica were evaluated for their potential anti-malarial properties. Methods: The plant materials were extracted successively with petroleum ether (PE), dichloromethane (DCM), ethyl acetate (EtOAC), ethanol, and ethanol-water (1:1 v/v) by cold maceration method. Cell free beta-hematin formation assay were used for assessing anti-malarial activity of obtained extracts. Results: DCM extract of A. kopetdaghensis and PE extract of A. turcomanica showed remarkable anti-malarial activity with IC50 values of 1.04 +/- 0.02 mg/mL and 0.90 +/- 0.27 mg/mL, respectively, compared to positive control (chloroquine, IC50 0.04 +/- 0.01 mg/mL). Conclusion: It seems that the anti-malarial activity of these extracts might be bound up with the presence of compounds with low or medium polarity; hence, this preliminary test indicated that these potent extracts could be considered for further investigations to find new sources of anti-malarial phytochemicals. | |
