ABSTRACT
Objective To establish the multi-wavelength fusion HPLC fingerprints of Gardeniae Fructus and to make quantitative analysis of the common peaks by ESI-Q-TOF MS. Methods The Kromasil 100-5 C18 column was used with a mobile phase of acetonitrile-0.1% phosphoric acid in gradient elution; The flow rate was 1.0 mL/min; The column temperature was 35 ℃; The detection wavelength was 238, 327, and 440 nm. Matlab7.1 was adopted for multi-wavelength fusion of the data in CSV format. Results Twenty chemical constituents were detected in fusion fingerprint, which included more information. Sixteen chemical constituents were compared with reference standards and identified by MS. The similarity of 10 batches of Gardeniae Fructus was over 0.90. Conclusion The systematic quantified fingerprint method based on the technique of multi-wavelength fusion fingerprint and identifying 16 constituents can be used for the fully quality control of Gardeniae Fructus.
ABSTRACT
Objective: To establish the fusion-fingerprint of Coicis Semen oil. Methods: The Coicis Semen oil was analyzed by GC-MS and HPLC-ELSD, and the fusion-fingerprint was originated from the Computer Aided Similarity Evaluation software based on the normalized data acquired by the above two methods. Results: Twenty-one common peaks existed in the fusion-fingerprint of which there were 13 kinds of aliphatic esters detected by GC-MS and 8 kinds of triglyceride ingredients detected by HPLC-ELSD. Conclusion: The fusion-fingerprint established on GC-MS combined with HPLC-ELSD could provide integrity and more information for the quality control of Chinese materia medica.
