To assess biological potential of B. erucago, we investigated its antioxidant activity using DPPH and FRAP assays, cholinesterase inhibitory activity against acetylcholinesterase and butyrylcholinesterase by using the Ellman method, and the cytotoxic activity against two human bladder cancer cell lines (T24 and TCCSUP) by using the MTT method. This evidence concerns the gene BCHE and urinary bladder carcinoma.
