HPLC Fingerprint Analysis of Acetoacetate Extraction of Polygonum orientale
摘要
Abstract
Objective; To establish the HPLC fingerprint analysis method for the quality control of acetoacetate extraction of Polygonum orientate. Methods: Agilent Cl8(4.6 mm x250 mm,5 μm) ;DAD detector;Mobile phase;methyl alcohol-water gradient elution at a flow rate of 1. 0 miymin,and at a column temperature of 30 °C. Results; 26 peaks were selected as the common fingerprint peaks. The relative standard deviations for relative retention values were less than 3% in the precision and repeated test. Conclusion; The repetition , stability and precision of the method is good and it can be used to control the quality of Polygonum orientate.关键词
