Abstract

A capillary gas chromatographic method for analyzing asarone and its related substances was established.The sample was analyzed on a HP-1 capillary column(30 m×0.530 mm i.d.,1.5 μm),the detector was flame ionization detector(FID) and the column temperature was set at 185 ℃.The method can be used for the determination of three compounds: β-asarone,2,4,5-trimethoxybenzaldehyde,1-(2,4,5-trimethoxyphenyl)-1-propanol.The linear range for the detection of asarone was 0.010～10.140 μg(r=0.9995),the average recovery of the method was 99.5%(n=9),and the detection limit of asarone was 0.304 ng.The established GC method is accuracy and sensible for asarone determination.It will play an important role in quality control of synthetic process.
