Title: Determination of the Content of Magnolol and Honokiol in Banxia-Houpu Effervescent Tablets by HPLC
Abstract: ObjectiveTo establish a method for determining the content of magnolol and honokiol in Banxia-Houpu effervescent tablets.MethodsMagnolol and honokiol were separated with Elite C_(18)column(4.6 mm × 200 mm,5μm) and detected at 294 nm,using methanol-acetonitrile-water(31.5∶38.5∶30.0)as mobile phase.ResultsThe standard curves for magnolol and honokiol were linear in the range of 0.54~13.61μg(r=0.999 7) and 0.11~2.82 μg(r=0.999 7).The average recoveries of magnolol and honokiol were 100.92%(RSD=1.79%) and 101.23%(RSD=1.79%).ConclusionThe method is simple and quick,which is suitable for practical use.
