Study on HPLC Fingerprint of Desmodium styracifolium and Its Preparations / 中国药房

ABSTRACT

OBJECTIVE:To establish RP-HPLC fingerprints of Desmodium styracifolium and its preparations in order to provide basis for the quality evaluation of them.METHODS:The separation was performed on ODS-C18(250 mm?4.6 mm,5 ?m) column with mobile phase consisted of methanol-20% phosphoric acid(gradient elution).The detection wavelength was set at 360 nm and flow rate was 1.0 mL?min-1.Column temperature was set at 25 ℃.The RP-HPLC fingerprint of D.styracifolium and its preparations were recorded.RESULTS:There were 13 common peak in RP-HPLC fingerprint of D.styracifolium and its preparations.CONCLUSION:The method is accurate,stable and reproducible for basis of quality evaluation and RP-HPLC finger print of D.styracifolium and its preparations.
