Objective To develop an HPLC wavelength switching method for determination of taxifolin,alpinetin,pinocembrin,cardamonin,alnustone and α-cyperone in Yangweining capsule simultaneously. Method The Agilent Eclipse XDB C18(250 mm×4.6 mm,5 μm) chromatographic column was adopted.The mobile phase was methanol-0.1% phosphoric acid solution with gradient elution,at a flow rate of 0.9 mL/min.The column temperature was set at 25 ℃. Results The linear response range were 2.18-54.50 μg/mL(r=0.999 9),7.89-197.25 μg/mL(r=0.999 6),6.57-164.25 μg/mL(r=0.999 8),4.89-122.25 μg/mL(r=0.9997),5.76-144.00 μg/mL(r=0.999 9),1.79-44.75 μg/mL(r=0.999 1) of taxifolin,alpinetin,pinocembrin,cardamonin,alnustone and α-cyperone,respectively.The average recoveries and the corresponding RSD were 97.33% (RSD=1.13%),100.18% (RSD=0.59%),98.47% (RSD=1.49%),97.42% (RSD=1.36%),99.04% (RSD=0.80%),96.99% (RSD=0.95%),respectively. Conclusion The method with good reproducibility is simple and accurate,which provide a new mind for quality assess of Yangweining capsule. |
