OBJECTIVE: To establish a RP-HPLC linear gradient elution method for simultaneously determining notoginsenoside R1, ginsenoside Rg 1, ginsenoside Rb1 and ginsenoside Rd in Xueshuantong injection. METHODS. An Agilent SB-C18 column (4.6 mm × 250 mm, 5 μm) was used with the mixture of acetonitrile-phosphoric acid-water as the mobile phase in linear gradient elution. The wavelength of detection was set at 203 nm. RESULTS: The response was linear over the wide concentration ranges. The average recoveries of R1, Rg1, Rb1 and Rd were 103.3%, 101.8%, 99.6% and Rd 103.9%, respectively. RSD of the assay was not more than 1.2% (n = 5). CONCLUSION: The method appeared to be accurate, sensitive and reliable, and can be used to control the quality of Xueshuantong injection.
