The ferulic acid has been identified as main compound in the both extracts. The both extracts showed weak antioxidant activities. The extracts showed weak antibacterial activity against only P. aeruginosa among the 15 microorganisms by agar well diffusion assay. The cytotoxic effects of extracts on MCF-7 (human breast cancer cell lines) and fibroblast cells during 24 and 48 hours were determined by MTT method. The extracts showed weak cytotoxic activity on MCF-7 during 24h. Article Details How to Cite ALBAYRAK, Sevil; KAYA, Onur. S,Albayrak Assoc.Prof.Dr..
