Determination of five components in Muxiang Fenqi Pill by HPLC / 中成药

ABSTRACT

AIM: To establish a method of simultaneously determining 5 components in Muxiang Fenqi Pill(Flos Caryophylli,Radix Aucklandiae,Cortex Magnoliae Officinalis). METHODS: Five componentseugenol,(costunolide),dehydrocostuslactone,magnolol and honokiol in Muxiang Fenqi Pill were determined simultaneously by HPLC,using a Kromasil C_(18) column(250 mm?4.6 mm,5.0 ?m),acetonitrile-menthanol-water(50∶8∶42) as a mobile phase.The detection wavelength was at 210 nm. RESULTS: The relationship between the concentrations and the peak areas of eugenol,costunolide,dehydrocostuslactone,magnolol and honokiol were linear respectively.The RSD of precision,repeatability and recovery were all less than 1.5%. CONCLUSION: The method is simultaneous determination for five components in Muxiang Fenqi Pill,and can be applied to the quality control of Muxiang Fenqi Pill.
