Abstract:

Objective: To analyze the UV fingerprint spectra of Pinellia ternate Breit. by common and variation peak ratio dual index
sequence analysis. Methods: Chemical constituents of Pinellia ternate Breit. were extracted by petroleum ether, chloroform, ethanol and water from different medicinal ingredient polarities, and the differences among those samples were analyzed by the way of UV fingerprint spectra. Results: This method could distinguish Pinellias ternate Breit. from different origin. Conclusion: The method was simple and with wide range of application, it provided a convenient method to estimate the quality of Pinellia ternate Breit..

Key words: Pinellia ternate Breit., UV fingerprint spectra, common peak ratio, variation peak ratio, dual index sequence analysis
