Objective: To develop a HPLC method for determining vitexin in Microcos Folium. Method: HPLC determination was performed on a Agilent ZORBAX Eclipse XDB C18 column(4.6 mm×250 mm
5 μm) with methanol and 0.4% phosphoric acid(30∶70) as mobile phase. The column temperature was at 35 ℃
and detection wavelength was set at 339 nm. Result: Vitexin showed a good linear relationship in the range of 88.96-2 224 μg. The average recovery was 98.61% and RSD was 1.32%. The contents of vitexin in Microcos Folium of Guangdong was higher than that of Guangxi. Microcos Folium of Guangdong was all in line with the standards stated in current pharmacopeia. Conclusion: The method is quick
simple and reproducible
which can be used to control the quality of Microcos Folium.
