Study On The Method Of Quality Assessment Of Radix Notoginseng

Panax Notoginseng (Burk.) F.H. Chen of Araliaceae is known as an important crude drug in traditional Chinese medicines. It is widely used to disperse stasis , stanch bleeding , detumescence , calm ache , risist thrombus and enhance organism immunity . In this paper, 29 samples were collected including 21 Radix Notoginseng samples from different areas and its eight common fakes . The HPLC analysis was performed on the following conditions : a luna C₁₈(2) column (250mm×4.6mm ID,5μm), the mobile phase of acetonitrile-0.05%phosphoric acid gradient elution , the detected wavelength at 203 nm , and caffine as internal standard . The chemical constituents in the methanol extract of them were determined by the method . In 70 minutes , 26 original chemical features as whole were obtained including 12 common chemical features and the chromatogram for 16-28min was significant in feature. By studying the correlation , the precision , the reappearance , the stablity , the exclusiveness and the similarity of the chromatogram , the High Pressure Liquid Chromatograph Fingerprint(HPLC-FP) of Radix Notoginseng was established . For the 29*26 steps data matrix obtained, the cluster anzlysis was done by applying SPSS software , Euclidean as measure and ward's as method . The 29 samples were assembled for 3 clusters : the superior , the ordinary and the fake . Moreover, the 8 commom peaks in feature was determined on the...
