- W2387765263 abstract "Objective:A method for rapid determination of eleven colouring agent in Saffron and Safflower(included Amaranth,Ponceau 4R,Orange G,Sunset Yellow,Allura red,Ponceau 2R,Acid Red 73,Orange II,Pyrosine,New red,808 Scarlet) was developed.Methods: The sample was extracted by 70% ethanol,gradient elution with methanol and 0.05 mol/L ammonium acetate and then detected by Photo-Diode Array Detector.Results: The limits of quantitation(LOQs) of the method were 0.90 mg/kg～1.50 mg/kg,and fortified recovery of reference substance solutions at two levels were 94.6%～102.5%,the RSDs were below 2.2%(n=3).Eleven reference substance solutions were separated well in forty five minutes.Many colouring agent were detected in Saffron and Safflower as Ponceau 4R,Sunset Yellow,Allura red and Orange II.Conclusion: This method is simple,rapid,and reproducible,and it can be used as a low-cost, convenient method for measuring colouring agent in Saffron and Safflower,and it can provide reference or help for relative company and State food and drug administration." @default.
