ABSTRACT
AIM:
A new method for the overall quality control of Radix Scutellariae has been established by HPLC digitized fingerprint.METHODS:
The chromatographic fingerprints were obtained from injecting 5 ?L of the sample solution each time on a CenturySIL C_(18) BDS column(200 mm?4.6 mm,5 ?m) with the gradient elution solvent system composed of 1% acetic acid water and 2% acetic acid acetonitrile.The flow rate was 1 mL/min,the column temperature was maintained at(30?0.15)(?C) and the detection wavelength was set at 280 nm.The chromatographic fingerprints were evaluated by the software of the digitized evaluation system of Traditional Chinese Medicine fingerprint with the super information characteristics.RESULTS:
30 co-possessing peaks were selected as the fingerprint peaks of Radix Scutellariae and the similarities between the chromatographic fingerprints and the herbal drugs were calculated by taking baicalin peak as the referential peak.The chromatographic fingerprints were also evaluated by the chromatographic fingerprint index(F).CONCLUSION:
This method with good precision and reproducibility can be applied to the quality control of Radix Scutellariae.
