High-performance liquid chromatography fingerprint of marine traditional Chinese medicine haliotidis

Objective: Haliotidis, the dried muscle of abalone, has long been used as a marine traditional Chinese medicine (TCM) due to its high medicinal and nutritive values, whereas few reports contributed to its quality control. This study aimed to establish the high-performance liquid chromatography (HPLC) fingerprints of Haliotidis. Materials and Methods: The HPLC fingerprints of Haliotidis, the manufacturing products of dried muscle of abalone, were analyzed by reverse-phase HPLC, using a YMC HPLC C18 column (250 mm × 4.6 mm, 5 μm). The gradient elution mode was applied with mobile phase starting from 5% acetonitrile and 0.1% phosphoric acid aqueous solution to 100% acetonitrile in 70 min at a flow rate of 1.0 mL/min. The detection wavelength was set at 190 nm. Results: Through compared the HPLC fingerprint chromatograms of 14 batches of Haliotidis, 25 peaks were assigned as the characteristic common peaks, of which one index component L-phenylalanine was identified by comparison with its standard substance. The established HPLC fingerprint analysis method of Haliotidis was validated with good precision, repeatability, and stability. Based on the above study, a reference HPLC fingerprint chromatogram of Haliotidis was proposed. Conclusions: It is the first time to establish the HPLC fingerprint chromatogram of TCM Haliotidis, which could contribute to the establishment of its quality control system.
