摘要：采用毛细管气相色谱-傅里叶变换红外光谱联用技术法(气红联用，GC-FTIR)，结合计算机检索对标准桃金娘油化学成分进行分析和鉴定，用气相色谱面积归一化法测定各组分的相对百分含量;经毛细管色谱从标准桃金娘油中分离出12个峰，并且采用FTIR法确认了所含的化合物。标准桃金娘油主要成分为三种单萜，分别为1，8-桉叶素、D-柠檬烯和α-蒎烯，含量分别为46.35%，36.83%和14.70%，三者占总量的97.88%，分析结果与GC-MS分析相一致。由于GC-FTIR分析能确定出经气相色谱分离后的有机物的异构体，故与GC-MS分析相比较，此法具有更广泛的应用价值。该研究可为综合利用开发桃金娘科植物提供科学依据。

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.
