| Abstract: | This study aimed to build the high performance liquid chromatography （HPLC） fingerprint of authentic medicinal material Platycodon grandiflorum in Shangluo, and to provide reliable data for the geoherbalism study of this medicinal material. Thirty - nine Platycodon grandiflorum samples from 7 counties （districts） of Shangluo city were determined by using HPLC under the following chromatographic conditions： using Hypersil C18 column （250 mm × 4.6 mm, 5μm）, mobile phase being the mixed solution of aeetonitrile and H3 POa, adopting gradient elution mode, flow velocity being 0.5 mL/min, detecting wavelength being 210 nm,and column temperature being 30℃. Finally, we built the HPLC fingerprint of 39 batches of Platycodon grandiflorum, and found out 18 common characteristic peaks. It was concluded that this method was simple with good repeatability, and could be used for the identification and evaluation of authentic medicinal material Platycodon grandiflorum in Shangluo. |
