同时蒸馏萃取－GC/MS法分析檵木与红花檵木叶挥发油成分

[Objective] The aim was to compare volatile oils component of Loropetalum chinense and L. chnreuse var. rubrum, and provide basis for development and utilization. [Method] Volatile oils were extracted from three kinds of leaves, including the leaves of L. chinense, the green and red leaves of L. chinense var. rubrum, with the simultanuous distillation and solvent extraction (SDE) device. They were divided and identified by GC-MS. [Results] The results showed that there were 44, 55 and 36 components separated from related leaves, 25, 21, 23 components had been identified, which accounted for 74.11%, 83.94%, 76.88% of the total extraction, respectively. The more abundant components in the extraction were as follows: 3-Hexen-1-ol, (Z)-(38.79%, 12.73%, 30.47%), n-Hexadecanoic acid (5.31%, 17.47%, 6.02%), Octadecanoic acid (1.99%, 5.03%, 2.55%), Oleic acid (2.63%, 33.31%, 9.13%). [Conclusion] These components could be used in many fields such as medicine and health care, spices, food additive and antibiotic insecticide.
