Abstract:

In this study, HPLC analysis on Shixia longan (Dimocarpus longan Lour. cv. Shixia) was performed on reversedphase Nucleosil C18 column (250 mm × 4.0 mm, 5 μm) by using mobile phase 0.01 mol/L KH2PO4 and CH3OH, dual gradient elution was proceeded with the flow rate of 0.8 ml/min, and operation conditions were set as follows: detection at 260 nm and column temperature 40 ℃. Results showed that there are 13 common peaks in HPLC chromatogram of water-soluble components of 14 Shixia longan samples collected from different areas. Moreover, by calculated with fingerprint analysis system of Chinese medicine, relative standard deviations (RSD) of relative retained time of common peaks are below 1.2% and their similarity is above 0.967. Therefore, the established chromatographic fingerprint is proved to be a scientific quality evaluation method for Shixia longan.
