ABSTRACT

Objective:

To establish the HPLC fingerprint and to determin gallic acid, methyl gallate, corilagin, and ellagic acid in Terminalia billerica, in order to provide the scientific foundation for quality control of T. billerica.

Methods:

The analysis was performed on Atlantic T3 (250 mm × 4.6 mm, 5 μm) C18 column, mobile phase was acetonitrile-0.2% glacial acetic acid aqueous solution with gradient elution, flow rate was 1.0 mL/min, injection size was 20 μL column, and temperature was maintained at 30 oC. The common mode of T. billerica HPLC fingerprint was established, the hidden information was analyzed in the fingerprint by Chemometrics, and the components in T. billerica by HPLC-MSn and quantitative analysis characteristic peaks were identified.

Results:

There were 21 common peaks in the diagram and the similarity of the fingerprints was over 0.9 in all 11 batches. The information of the 18 common peaks in T. billerica was summarized by HPLC-MSn technology. The samples were broadly divided into three kinds by principal component analysis and clustering analysis. The five key compounds were verified by partial least squares discriminant analysis method in quantitative analysis, and identified that the No.12 peak was chabulagic acid, and the average recoveries were in the range of 97.24%-98.58%.

Conclusion:

The HPLC fingerprint method and content determination method are reliable, accurate, rapid, simple, and reproducible, and this study could control the quality of T. billerica.
