摘要
目的 :测定肝纤维化大鼠肝脏中羟脯氨酸含量。方法 :采用2 ,4—二硝基氯苯柱前衍生化反相高效液相色谱法 ,以乙晴 -醋酸盐缓冲系统梯度洗脱 ,于360nm波长处测定羟脯氨酸含量。结果 :羟脯氨酸衍生物与其它氨基酸较好分离 ,并可准确定量。结论 :本方法快速、灵敏 ,分辨率高 ,尤其适用于临床肝纤维化患者肝穿刺后样本量极小的情况。
OBJECTIVE:To determine the content of hydroxyproline in liver tissue in rats with hepatic fibrosis.METHO_ DS:RP-HPLC was used with precolumn derivation by2,4-dinitrochlorobenzene(DNCB)in the Borax buffer solution for lh in boiling water.Acetonitrile-acetate buffer linear gradient elution was used.Detecting wavelength was360nm.RESULTS:Derivation of hydroxyproline could be separated from other amino acids and accurately determined.CONCLUSION:The method is rapid,accurate,and suitable for detection of biopsy samples obtained by liver puncture.
