摘要
目的：建立莪术中莪术醇的含量测定方法。方法：采用气相色谱方法，HP-5（0．32mm×30m，0．25μm）石英弹性毛细管柱，进样口温度200℃，氢火焰检测器（FID）250℃，不分流，柱流量1．0mL·min^-1；程序升温：初始60℃，保持4min，以3℃·min^-1升至210℃。结果：莪术醇在40．0-2000μg·mL^-1具有良好的线性关系，r=0．9997，高，低浓度加样回收率分别为95．01％（RSD 2．52％），96．46％（RSD 2．86％）。结论：本方法准确可靠，重复性好，样品处理较简单。
Objective： To establish a method to determine the content of Curcumol in Bhizoma Curcumae. Method： The samples were determined by GC on a HP-5 column （0.32 min×30 m, 0.25μm）, Inlet temperature 200℃, FID 250℃, flow 1.0 mL·min^-1 ,splitIess. Temperature programming started at 6℃, holding for 4 rain, then increased to 210 ℃ at a rate of 3 ℃ min^-1. Result： The calibration curve of curcumol is linear over the range of 40.0-2 000 μg·mL^-1, r = 0.999 7. The high and low additive recovery were 95.01% （BSD 2.52% ）, 96.46%（RSD 2.86% ）. Conclusion： This method was accurate and reliable with a good reproducibility, and the procedure of samples pretreatment is simple.
