Abstract: Objective: To establish a method for determination of L-citrulline in Tianhuafen Formula Granules by high performance liquid chromatography coupled with evaporative light scattering detection. Methods: The analytical column was Inertsil ODS-SP(4.6 mm×250 mm,5 μm).The mobile phase was water,and the sample was determined by an evaporative light scattering detector with the flow rate 0.5 mL·min-1. The flow rate of atmosphere was 3.0 L·min-1 and the temperature of drift tube was kept at 110 ℃. Result: The logarithm correlation between peak area and the concentration of L-citrulline had good linearity in the range of 0.05~1.00 mg·mL-1,and the average recovery was 97.9%. Conclusion: The method is a rapid, convenient,and effective method for qualitatively analysis of L-citrulline in Tianhuafen Formula Granules.
