薄荷素油的GC指纹图谱

目的：建立薄荷素油的GC指纹图谱。方法：采用弹性石英毛细管柱HP—FFAP（25m×0．20mm×0．33μm）；进样口温度250℃；Fid检测器检测器温度300％；载气为氮气；流速1．0ml·min^-1；分流比10：1；进样量1μl；程序升温：初始柱温65％，以5℃·min^-1升至100℃，再以2℃·min^-1升至200℃，总时间57min。结果：薄荷素油的GC指纹图谱由14个共有峰构成，所建立的指纹图谱具有稳定、重复性好的特点。结论：方法准确、简单，适用于薄荷素油的质量控制。

GC Fingerprint of Peppermint Oil

Objective ： To establish GC fingerprint of peppernint Oil. Method ： The flexible quartz capillary column HP-FFAP （ 25 m ×0.20 mm ×0.33μm） was used, the detertor was FID, the injection port temperature was 250℃ ; the detector temperature was 300℃ ; the carrier gas was nitrogen; the flow rate was 1.0 ml · min^-1 ; split ratio 10：1 ; injection volume luL; programmed temperature： the initial column temperature 65℃, with 5℃ ·min^-1 up to 100℃, and then to 2℃ · min^-1 up to 200℃. The total lime 57min. Result： The GC fingerprint of peppermint oil constituled 14 Coossessing peaks, the fingerprints were stable and repealable. Conclusion： This method is accurate, simple, it suitable can be used for quality control of peppermint oil.
