[Study on HPLC fingerprint chromatograms of cell wall-broken decoction pieces of Notoginseng].Zhong Yao Cai. 2012 Jul; 35(7):1056-61.ZY
To establish the HPLC fingerprint chromatograms of crude Notoginseng, cell wall-broken powder and cell wall-broken decoction pieces of Notoginseng and provide evidence for quality control of cell wall-broken decoction pieces of Notoginseng.
The HPLC procedure was performed on the chromatographic column of Hypersil ODS2, and the mobile phase was acetonitrile and water in gradient elution with the flow velocity of 1.0 mL/min. The detection wavelength was 203 nm and the column temperature was 25 degrees C. The chromatograms was analyzed with the software of "similarity evaluation system for chromatographic fingerprint of TCM".
Eight common peaks were pinpointed from the chromatograms of different batches of crude Notoginseng, cell-broken powder and cell-broken decoction pieces, the similarities of the chromatograms were all larger than 0.9.
The method of the HPLC fingerprint chromatogram is of good precision, reproducibility and stability,which is suitable for quality control of cell wall-broken decoction pieces of Notoginseng.
