Abstract:
The alkaline and enzymatic extractions of a glycoconjugate from fish scale were researched. The best extraction reagent, the concentration of the extraction reagent, the solid- fluid ratio and the extracting time were found to be NaOH solution, 0.3 mol/L , 1:5 and 18 h, respectively. Evaluation of the antioxidatnt activity of the achieved glycoconjugate showed that the glycoconjugate could efficiently scavenge DPPH•, O2.- and •OH . Besides, it had high reducing capacity and strong ability to prevent lipid peroxidation.
