摘 要：
[Objective] The research aimed to provide basic data for the development and culture of Longchang Sheldrake.[Method] The chromogenic system for the determination of cuprum content by 5-Br-PADAP spectrophotometry was studied and it was applied in the determination of cuprum content in the viscera of Longchang Sheldrake.[Result] The linear range of cuprum content in the viscera of Longchang Sheldrake was 0-7.5 μg/25 ml and its regression equation was A=0.031 05C-0.019 7(r=0.999 1).The addition recovery rate was 97.5-104.2%.The order of cuprum content in the viscera of Longchang Sheldrake was liver>heart>kidney>liver>lung.[Conclusion] This method was simple and highly-sensitive and it can be used in the determination of cuprum content in the viscera of Longchang Sheldrake.
