A quality evaluating method using high-performance liquid chromatography-diode array detector-electrospray ionization-tandem mass spectrometry (HPLC-DAD-ESI-MS/MS) was proposed for Comastoma pedunculatum (Rogle ex D. Dou) Holub, a traditional Tibetan herbal medicine. The optimum extraction conditions for herbal samples were firstly optimized using multi-responses optimization based on response surface methodology (RSM), and achieved by Derringer's desirability function and experimental validation. In the fingerprint analysis, 17 common peaks was developed among 10 batches of C. pedunculatum samples. 14 common peaks were identified using HPLC-DAD-ESI- MS/MS method based on their spectral characteristics or comparison with the authentic standards. Chemometrics techniques including similarity analysis, and hierarchical clustering analysis were implemented to discriminate the 10 batches of samples collected from different origins. The results indicated that the 10 batches of samples shared two principle chromatographic patterns as well as differences. These results provided an effective and comprehensive quality analysis method for C. pedunculatum.
