ABSTRACT
Objective:To establish a method for quality evaluation of Myristica fragrans Houtt. Methods:The common peak was determined with Dehydroisoeugenol as the reference peak, and the HPLC fingerprint of Myristica fragrans was established; then the common peaks were analyzed by High Resolution Liquid Chromatography-mass Spectrometry (HPLC-MS). The chemical components of the common peaks were identified through the calculation and data retrieval of the primary and secondary mass spectra of the characteristic peaks. Results:The HPLC fingerprint of Myristica fragrans was established, and the similarity degree of the 10 batches of samples was above 0.9 and 11 common peaks were established. According to the results of HPLC-MS, the components of 11 common peaks were identified as follow: Methyl eugenol (peak 1), Licarin A (peak 2), Myristol (peak 3), OdoratisolA (peak 4), 2-(3,4-Dimethoxyphenyl) butynoic acid (peak 5), Malabaricon D (peak 6), 5'-Methoxydehydroisoeugenol (peak 7), Dehydroisoeugenol (peak 8), Malabaricone C (peak 9), 4-Methoxy-6-{(2S,3S)-7-methoxy-3-methyl-5-[(1E)-1-propen-1-yl]-2,3-dihydro-1- benzofuran-2-yl}-1,3-benzodioxole (peak 10) and Licarin B (peak 11). Conclusions:The quality of Myristica fragrans could be evaluate with HPLC fingerprint method. HPLC-MS was used to analyze the chemical composition of complex components, which will provide reference for the identification and analysis of chemical components of the extracts and preparations of Traditional Chinese Medicine.
