Objective: To develop an HPLC method for simultaneous determination of five compounds
including three iridoid glucosides (10-acetyl-scandoside
scandoside methyl ester
and deacetylasperuloside methyl ester) and two flavonoid glucosides {quercetin-3-O-[2-O-(6-O-E-ferloyl)-β-D-glucopyranosyl]-β-D-galactopyranoside and kaempferol-3-O-[2-O-(6-O-E-ferloyl)-β-D-glucopyranosyl]-β-D-galactopyranoside} in Hedyotis diffusa injection. Method: The separation of targeted compounds was performed on SunFireTM C18 column (4.6 mm×250 mm
5 μm) with acetonitrile-0.1% formic acid solution as the mobile phase for gradient elution. The column temperature was 30℃ and the flow rate was 1.0 mL·min-1. Result: The method showed good linearity (r>0.999 5) within the linear range. The recoveries were in the range of 98.1%-101.2% with RSD<3.3%. Conclusion: The method is reliable
simple and reproducible
and it can be used to control the quality of Hedyotis diffusa injection.
