HPLC Fingerprint of the Ethyl Acetate Extracts from Zherong Radix Pseudostellariae

To protect geographical indication products,ZheRong radix pseudostellariae was collected at the 31 village of ZheRong County eight villages and towns in fujian province. A HPLC chromatographic fingerprint of the ethyl acetate extracts was developed.A suitable chromatographic system was established using a gradient elution with acetonitrile and water as the mobile phase and a detection wavelength of 203nm. Establishment of HPLC fingerprints and common pattern of 31 samples. The similarities of non- ZheRong Radix pseudostellariae were all less than 0.2, but the similarities of Radix pseudostellariae from commercially available were all more than 0.9.Then this method could efficiently distinguish non-ZheRong Radix pseudostellariae from ZheRong Radix pseudostellariae.
