Abstract

Centaurea is the largest genus within the Asteraceae family. Many members of this genus are used in traditional folk medicine, such as Centaurea pulchellaused to treat skin problems such as to resolve the abscess. Although biological activities of many Centaurea species have been investigated in differentcountries and Turkey, cytotoxic effect of C. patula, C. pulchella and C. tchihatcheffii has not been studied yet. Melanoma is one of the most invasive anddeadly forms of skin cancer. Therefore, in an ongoing effort to identify new natural anticancer products for the treatment and/or prevention of melanomacancer, the present study was undertaken to investigate the effect of these Centaurea species, collected from Central Anatolia region of Turkey on cell growthand death in human melanoma cell line, A375.The results revealed that all extracts were able to inhibit, after 48 h of treatment, the growth of cancer cells, thatcould be related to an overall action of the phenolic compounds present. In fact, C. pulchella, with the highest level of phenolics, showed a major activityfollowed by C. patula and C. tchihatcheffii. Our data also demonstrate that these natural products induce apoptotic cell death. In conclusion, the study of plantextracts for their cytotoxic and apoptotic properties has shown that medicinal herbs from Centaurea species might have also importance in the prevention andtreatment of melanoma.
