| 摘 要： | 目的建立测定薰衣草油中芳樟醇和乙酸芳樟酯含量的方法。方法采用气相色谱法，HP-5GC色谱柱（30m×0．32mm，0．25μm）；柱温为80℃，保持5min，以4℃／min的速率升温至160℃；检测器为FID，250℃。结果芳樟醇和乙酸芳樟酯质量浓度线性范围分别是0．39～5．90mg／mL（r=0．9995）和0．40～6．06mg／mL（r=0．9998），平均回收率分别为100．33％和100．37％，RSD分别为0．58％和0．75％（n=6）。结论所用方法简便、准确、重现性好，可作为薰衣草油的质量控制方法。

| Abstract: | Objective To establish a method for the determination of linalool and linalyl acetate in lavender oil. Methods The GC method was adopted with HP-5 GC column （30m×0. 32 mm, 0. 25 μm）, the column temperature was set at 80℃ for 5 min, and then heated up from 80℃ to 160 ℃ with the rate of 4 ℃/min, using FID detector. Results Within the range of 0, 39-5.90 mg/mL and O. 40-6.06 mg/mL for linalool and linalyl acetate respectively, the linearity of this method was good. The average recovery rates of linalool and linalyl acetate were 100.33% with RSD of 0. 58% and 100. 37% with RSD of 0. 75% respectively （ n =6）. Conclusion The method is simple, accurate and reproducible. It can be used for the quality control of lavender oil. |
