摘 要：
采用氨水-过氧化氢法和碳酸钾-过氧化氢法对乌骨鸡黑色素进行降解,并通过傅里叶红外光谱法对乌骨鸡黑色素及其降解产物可溶性部位的红外光谱学性质进行研究。结果显示:乌骨鸡黑色素降解产物可溶性部位与乌骨鸡黑色素在红外图谱上有较多相似之处,在3600～3100cm-1、2950～2850cm-1、1680～1630cm-1、1570～1515cm-1、1240～1200cm-1均有不同强度的吸收峰,特别是在1650cm-1附近均出现乌骨鸡黑色素的特征强吸收峰,推测经过氧化氢降解反应获得的乌骨鸡黑色素降解产物可溶性部位中含有乌骨鸡黑色素骨架结构片段,酰胺基团和环状烯烃可能是构成乌骨鸡黑色素骨架结构的主要基团。

摘 要：
Melanin from black-bone silky fowl(BSFM) was degraded by NH4OH-H2O2 and K2CO3-H2O2 methods.BSFM and its soluble degradation products were studied by Fourier transform infrared spectroscopy.The results showed that the infrared spectra of BSFM and its soluble degradation products were much similar,and had characteristic absorption peaks in the ranges of 3600-3100 cm-1,2950-2850 cm-1,1680-1630 cm-1,1570-1515 cm-1 and 1240-1200 cm-1.From the absorption peak near 1650 cm-1,it could be speculated that backbone structure fragments of BSFM are present in its soluble degradation products derived from the action of H2O2 and that amide groups and cyclic-alkenes may be the major groups of BSFM backbone structure.
