Abstract: 目的建立反相高效液相色谱法测定鱼鳞中Ⅰ型胶原蛋白含量的方法。方法以ZORBAX 300SB-C18色谱柱(4.6mm×250mm,5μm)为分离柱,以(A)5%乙腈+0.05%三氟乙酸(TFA)和(B)90%乙腈为流动相,线性梯度洗脱20min,流速1.0mL.min-1,紫外检测波长230nm。结果Ⅰ型胶原蛋白在56~4681μg.mL-1浓度范围内与峰面积具有良好的线性关系(r=0.9997),精密度,RSD 0.83%(n=6),加标平均回收率为100.38%,RSD1.87%。结论该方法简便快速、灵敏、准确,为鱼鳞Ⅰ型胶原蛋白的质控与定量检测提供了1种新的测定方法。
