Objective: To develop a method for determining four kinds of saponins in Shenqi compound granules. Method: Quantitative analysis was carried out on a column of Phenomenex C18 (4.6 mm×250 mm
5 μm) by HPLC-ELSD with mobile phase of acetonitrile-water under a flow rate of 0.8 mL · min-1
column temperature was 25 ℃
flow rate of carrier gas was 2.6 L · min-1
drift tube temperature was 102 ℃. Result: Linear ranges of ginsenoside Rg1
ginsenoside Re
ginsenoside Rb1and astragaloside Ⅳ were 0.196-2.976
0.207-3.138
0.191-2.895
0.190-2.879 μg;their recoveries were 99.27%
99.33%
99.32%
99.27%
RSDs were 1.5%
1.1%
1.0% and 2.4%
respectively. Conclusion: This method is accurate
reproducible and convenient for quality control over Shenqi compound granules.
