Abstract The chemical constituents of the Mgrtol standardized were analyzed by capillary gas chromatography-Fourier transform infrared spectroscopy (GC-FTIR). The relative content of each component was determined by area nomalization method. Twelve peaks were separated and were all identified by FTIR through search method. The results showed that the Mgrtol standardized mainly consists of 3 kinds of single terpenes, including 1,8-cineole, D-limonen and α-pinene, which account for 14.70%,36.83% and 46.35% respectively, totaling to 97.88% of the entire compositions of the Mgrtol standardized. The results are the same as those analyzed by GC-MS. Comparing with GC-MS, the isomers of organic compounds separated by gas chromatography could be determined by GC-FTIR. So this method has wider application value. The results also provided a scientific proof for the further development of the plant.
