Abstract
OBJECTIVE To establish determination method for the content of protocatechualdehyde in Huamoyan Granule.METHOD High performance liquid chromatography was used to determine the content of protocatechualdehyde in Huamoyan Granule.RESULT The result of high performance liquid chromatography determination suggested that within the range of 0.001 5~1.005 μg, protocatechualdehyde assumed linear correlation, the average sample recovery rate was 99.22% and RSD was 0.72%.CONCLUSION This method is simple and reliable with good reproducibility, and therefore can be used in the quality control for Huamoyan Granule.
