RESUMO
Artemisia rupestris is a part of traditional Kazakh folk medicine. Extracts obtained from this plant are used to treat various diseases, including cancer. This study evaluates the anti-microbial, cytotoxic, and anti-cancer effects of different extracts of the plant. Different extraction techniques were used and the resultant activities were compared. Extracts of A. rupestris were prepared from the flowers plus the leaves and from the stems. The antimicrobial activity against Candida albicans and Staphylococcus aureus was quantified. Cell lines L1210 and THP-1 were used to evaluate the cytotoxic potential of these extracts in vitro. The anti-cancer effect was tested using L1210-induced tumorgenesis in mouse model. The aqueous extract of stems was the most active against C. albicans, whereas the methanolic extract of flowers plus leaves especially inhibited the growth of S. aureus. The aqueous extracts were found to be non-cytotoxic for both cell lines, whereas the lipophilic extracts showed cytotoxic effects. The extract obtained from flowers plus leaves was more cytotoxic than that from stems. The tested extracts showed no anti-cancer potential. The results obtained testify to the relatively safe consumption of aqueous extracts of A. rupestris, but lipophilic extracts showed toxic effects and their consumption should be considered more carefully.Key words: L1210 cell line THP-1 cell line microwave-assisted extraction ultrasonic-assisted extraction Candida albicans Staphylococcus aureus.
