Analysis on Essential Oil from Zanthoxylum bungeanum and Z. armatum by GC-MS-AMDIS Combing with Kováts Retention Index

Abstract:

Objective: Study on volatile oil composition and relative content of Zanthoxylum bungeanum and Z. armatum from different origin. Method: The volatile oil was extracted by steam-stilling. The chemical constituents of the volatile oil were detected and analyzed by GC-MS-AMDIS combing with Kováts retention index. Result: A total of 86 compounds in the essential oils of eight batches were identified. The highest level compound of two batches of Z. bungeanum from Sichuan is linalool, which represented 36.25% and 30.91%, respectively. The highest level compound of two batches of Z. bungeanum from Shaanxi is limonene, which represented 15.63% and 17.23%, respectively. The highest level compound of Z. armatum is linalool, accounting for 71.74%-75.03%. Conclusion: The volatile oil of Z. bungeanum and Z. armatum is significantly different;Z. bungeanum, which come from Sichuan and Shaanxi may belong to two different chemical types.
