Fingerprint of Carthamus Tinctorius L. by HPLC / 中成药

ABSTRACT

AIM:To establish the chromatographic fingerprint of Carthamus Tinctorius L.by high performance liquid chromatography(HPLC).METHODS:The chromatographic fingerprint of Carthamus Tinctorius L.was established by HPLC with a RP-C_ 18 column,acetonitrile-water(0.5 phosphoric acid)gradient elution,a DAD diode array detector at 275 nm and the flow rate of 1.0 mL/min,column temperature of 25 ℃。 RESULTS:34 co-peaks of Carthamus Tiuctorius L.were gained from 10 producing provinces.Its basic features were rough consistent each other.Hydrosafflor yellow A,was selected as marker,among samples the content of Xinjiang was the highest in the all samples.CONCLUSION:This method provides useful information for identification of traditional Chinese medicines,the fingerprints of samples of Carthamus Tinctorius L.can be used to control the quality combined with content determination.
