GC-MS Analysis of Volatile Oil Chemical Components of Uncultivated Mentha Arvensis L. from Shannxi
摘要
Abstract
Objective To analyze the chemical components of volatile oil in uncultivated Mentha arvensis L. picked from Shannxi province by GC-MS. Methods The steam distillation method was used to extract the volatile oil,then a appropriate amount of which were taken to prepare the solution for conducting analysis by GC-MS. The chromatographic column was HP-FFAP quartz capillary column(30 m × 0. 32 mm,0. 25 μm),the temperature of the injection port was 220 ℃. The column temperature was temperature pro-gramming and the initial temperature was set at 65 ℃ and kept for 3 min,then heated up to 230 ℃ with a rate of 5 ℃ /min and kept for 5 min. The carrier gas was N2 and the flow rate was 1. 5 mL/min. The split ratio was 1 :10. The mass spectrometry con-dition:the interface temperature was 230 ℃,the ion source temperature was 220 ℃. Results Totally 67 chemical compounds in the volatile oil from 5 batches of uncultivated Mentha arvensis L. were identified by GC/MS and the main components were menthol,levo-duction carvone and terpinyl acetate. Conclusion The kinds and relative contents of chemical components in volatile oil from unculti-vated Mentha arvensis L. picked from Shannxi have large difference due to different growth environments,populations and harvest time.关键词
