HPLC method for quantitative determination of Ginsenoside Rb1 in Jupizhuru decoction / 国际药学研究杂志

Objective To develop an HPLC method for the determination of ginsenoside Rb1 in Jupizhuru decoction,and de-termine the amount of ginsenoside Rb1 in 10 batches of Jupizhuru decoction composed of different batch herbs. Methods The HPLC analysis was carried out on a Phenomenex Luna C18 column with column temperature at 30℃,flow rate 1.0 ml/min,detection wave-length 203 nm and mobile phase acetonitrile and 0.1%phosphoric acid by gradient elution. Results The method was found to be lin-ear within the ranges of 5-500μg/ml(r=0.9999),and the average recovery of ginsenoside Rb1 was 95.5%(RSD 1.77%,n=6). Con-clusion The determination method is suitable for the quality control of ginsenoside Rb1 in Jupizhuru decoction.
