“…BAs were eluted at 0.8 mL min À1 with acetonitrile (A) and water (B), using the following gradient: 65% A (1 min), 65e80% A (9 min), 80e90% A (2 min), 90e100% A (4 min), 100% A (7 min) (Moret, Smela, Populin, & Conte, 2005). BAs were quantified using calibration curves built up after having analysed standard solutions, containing the following amines dissolved in 0.1 M HCl at concentrations of 2, 5, 10, and 20 mg mL À1 : cadaverine, histamine, 2-phenylethylamine, putrescine, spermidine, spermine, tryptamine and tyramine.…”
