| Carnosine is a functional dipeptide regarded as an important antioxidant naturally occurs in vertebrate animal tissues. For its identification and quantification a simple and reliable method by combined use of HPLC/PAD/MS was developed. The assay was performed on a 5ìm Alltima NH2 column with acetonitrile:PB (60:40v/v) as mobile phase. In this paper carnosine was identified in the muscles of Black-bone silky fowl a particular chicken used in tradition Chinese medicine; and both contents of carnosine from Black-bone silky fowl and White Plymouth Rock were determined by HPLC used NH2 column without sample derivation. The results showed that the content of Carnosine is much higher in the muscles of Black-bone silky fowl than in White Plymouth Rock with 0.45% versus. 0.22%. In this case, Carnosine in Black-bone silky fowl is proposed to be included as a typical nutritional ingredient for its health-enhancing properties. |
