Objective: To study and analyze the content of sialic acid (SA) among different edible bird's nest (EBN)
so as to provide reference for EBN quality standard. Method: Using HPLC to detect the content of SA·2HCl is the derivatization reagent; the mobile phase consisted of acetonitrile-water(15:85); the flow rate was 1.0 mL·min-1]. Result: The water content in 25 kinds of EBN ranged from 9.13% to 17.58%
the SA content in 25 kinds of EBN ranged from 3.62% to 15.23% respectively. The content of SA in tremella and pigskin was found zero while using this method. Conclusion: The method is simple
reliable and precise
which could be used to identify the EBN
tremella and pigskin. Althought there's no difference among white
red and yellow EBN
the data could provide support for the further study on the quality of EBN.
