- Abstract: Lao-Xiang-Huang (LXH) of Chaozhou is the processed product of Fructus Citri sarcodactylis.LXH from different producing areas were used as research objects in the study for the establishment of HPLC fingerprints of LXH.Contents of hesperidin and 5,7-dimethoxycoumarin were also determined to provide scientific basis for the establishment of quality standard of LXH.Samples were separated by an Agilent Eclipse XDB C18 column (4.6 mm × 250 mm,5 μm) using acetonitrile-0.1％ phosphoric acid with water gradient system as a mobile phase.The flow rate was 1.0 mL· min-1.The injection volume was 20 μL.The detection wavelength was at 283 nm.The results showed that HPLC fingerprint of LXH was established with good separation and repeatability.The similarity evaluation on 27 batches samples of LXH showed that there was a certain similarity on the HPLC fingerprints of LXH.However,there was a certain difference as a whole.Contents of hesperidin and 5,7-dimethoxycoumarin in LXH were simultaneously determined.It was concluded that the established HPLC fingerprint of LXH and content determination of hesperidin and 5,7-dimethoxycoumarin method were accurate,sensitive and repeatable.It provided scientific evidence for the quality control standard of LXH of Chaozhou.
