Analysis and identification of volatile constituents in different parts of Murrayae Folium et Cacumen by HS-SPME-GC-MS / 国际药学研究杂志

ABSTRACT

Objective: To analyze,identify and compare the volatile components in different medicinal parts of Murrayae Folium et Cacumen(Kamuning). Methods: The volatile components were extracted by headspace solid-phase microextraction(HS-SPME)and analyzed by gas chromatography-mass spectrometry(GC-MS). The relative contents were calculated for each of the volatile components by the area normalization method. Results A total of 74 compounds were identified in the root,stem and leaf of Murrayae Folium et Cacumen,among which there were 8 components in common in the three parts,and the numbers of specific components in roots,stems and leaves were 23,27 and 32,respectively. Conclu- sion The present HS-SPME-GC-MS method was suitable for the analysis of volatile components in the different parts of Murrayae Folium et Cacumen. Some volatile components were identified to be medicinal ingredients. The present results provide a reference for further development and application of the Murrayae Folium et Cacumen resources.
