Background
Brain cancer is known to be one of the most difficult types of cancer to cure. It has a serious impact on the lives of diagnosed people due to the insufficient treatment options and their side effects. The search for new alternative treatments is therefore ongoing. Melocan (Smilax excelsa L.) and galdirik (Trachystemon orientalis) are of great importance in both traditional culinary culture and traditional medicine around the Black Sea; however, the knowledge about their antioxidant and cytotoxic effects remains fairly limited. Experimental approach: The
Conclusions
According to the results, the water extracts of Smilax excelsa and Trachystemon orientalis had higher TPC (expressed in gallic acid equivalents on dry mass basis: 1158.17 and 262 mg/100 g, respectively) than the ethanol extracts. TAA expressed in Trolox equivalents on dry mass basis was 192.86 and 131.92 mg/100 g for Smilax excelsa and Trachystemon orientalis, respectively. The MTT assay showed that Trachystemon orientalis had a greater cytotoxic effect. In conclusion, the findings of the current study are promising for the development of new drugs. Novelty and scientific contribution: This is the first study that aims to evaluate the potential cytotoxic activity of two local Turkish plants, Smilax excelsa and Trachystemon orientalis, against C6 glioblastoma cells. The results confirm that both plants could be used as good therapeutic agents for the treatment of cancer in the future.
