The invention discloses a method for measuring nitrofuran antibiotics in cosmetics. The method comprises the following steps: (1) pretreating a sample, namely adding the sample into a mixed solution of acetonitrile and methanol in a volume ratio of 70:30, uniformly mixing, performing ultrasonic extraction, centrifuging, airing supernatant till the supernatant is nearly dry, dissolving residues in a mixed solution of a 15mmol/L ammonium acetate solution and acetonitrile according to a volume ratio of 85:15, and sieving the solution through a micro-porous filter membrane with the size of 0.22 micron, thereby obtaining filtrate for later use; (2) performing high performance liquid chromatography separation on the filtrate, eluting a mobile phase by a gradient elution program, and quantifying according to an external standard method; and (3) confirming a detected positive sample by high performance liquid chromatography-mass spectrometry/mass spectrometry. According to the method, four nitrofuran antibiotics such as macrodantin, furazolidone, furaltadone and nitrofurazone are simultaneously detected. The method is accurate, reliable and high in sensitivity.
