ABSTRACT
AIM:
To develop the HPLC fingerprinting of Gynostemma pentaphyllum and evaluate the quality of different sources of G.pentaphyllum by fractal expression and wavelet analysis based on similarity calculation.METHODS:
Flavones of G.pentaphyllum were extracted by using methanol and the HPLC fingerprint analysis on an HPLC/DAD system was developed.The signal of chromatogram was decomposed into components at different resolution by wavelet transform.Furthermore,the fractal dimensions of these components were computed for similarity calculation.RESULTS:
With the optimized extraction and analytic tool,the fingerprint of G.pentaphyllum was developed.The similarity was effective in evaluating the quality of G.pentaphyllum.CONCLUSION:
To describe a fingerprint profile by factors based on fractal and wavelet transform was a more objective method.G.pentaphyllum from Zhejiang province can be used as a substituent for raw drug from Ankang,Shanxi province.
