Determination of seven volatile effective components in "Shexiang Zhuifeng Plaster" by GC

Objective To establish a method for determination of cineol,camphor,menthol,synthetic borneol,methyl salicylate,cinnamic aldehyde and eugenol in Shexiang Zhuifeng Plaster.Methods The GC was performed on HP-INNOWAX capillary column,nitrogen as the carrier gas,and FID as the detector.The temperature program of column oven was set as follows: 80℃ for 5min,increased to 150 ℃ at the rate of 60 ℃·min-1 for 5 min,increased to 200℃ at the rate of 80℃·min-1 for 2 min.The seven compounds in Shexiang Zhuifeng Plaster were detected by internal standard method.Results All the seven compounds in Shexiang Zhuifeng Plaster and naphthalene were separated.The average recovery rates of them were 96.23%(RSD=2.48%),100.31%(RSD=0.23%),96.76%(RSD=0.76%),96.90%(RSD=1.39%),98.52%(RSD=1.57%),96.32%(RSD=2.01%) and 103.31%(RSD=2.12%),respectively.Three batch samples were detected by this method,and have achieved satisfactory results.Conclusion The method is simple,accurate and separable,and can be used to control the quality of Shexiang Zhuifeng Plaster.
