HPLC-MS fingerprint of Radix Pseudostellariae / 中成药

AIM:To establish the analytical method for the fingerprint of Radix Pseudostellariae by HPLC-MS and to estimate the quality of Radix Pseudostellariae from different habitats. METHODS: Radix Pseudostellariae from different habitats were analyzed and the total ion current(TIC) chromatographic fingerprint were determined by HPLC-MS.Some characteristic peaks were identified preliminarily based on the MS spectra and literature data. RESULTS: HPLC-MS fingerprint of 10 main peaks was established preliminarily.It was found that a small number of samples differed from others obviously. CONCLUSION: The method is reliable,accurate and can be used for quality control of Radix Pseudostellariae.
