Determination of curcumol in Rhizoma Curcumae by GC / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To establish a method to determine the content of Curcumol in Rhizoma Curcumae.</p><p><b>METHOD</b>The samples were determined by GC on a HP-5 column (0.32 mm x 30 m, 0.25 micron), Inlet temperature 200 degrees C, FID 250 degrees C, flow 1.0 mL x min(-1), splitless. Temperature programming started at 60 degrees C, holding for 4 min, then increased to 210 degrees C at a rate of 3 degrees C x min(-1).</p><p><b>RESULT</b>The calibration curve of curcumol is linear over the range of 40.0-2,000 microg x mL(-1), r = 0.9997. The high and low additive recovery were 95.01% (RSD 2.52%), 96.46% (RSD 2.86%).</p><p><b>CONCLUSION</b>This method was accurate and reliable with a good reproducibility, and the procedure of samples pretreatment is simple.</p>
