Determination of Borneol in Houjiling Tablets by GC

Aim To establish a GC method for the determination of Borneol in Houjiling tablets.Methods The Rtx-50 capillary column(30 m×0.25 mm,0.25 μm) was used with FID,nitrogen as the carrier gas,column temperature at 130 ℃.The internal standard method was used to determine the content of borneol.Results The borneol sample showed a good linear relationship at the range of 0.405 4~2.027 0 g·L-1(r=0.999 0,n=5).The average recovery rate was 99.21% and RSD was 0.81%(n=9).Conclusion This method is simple and accurate and able to determine of Borneol in Houjiling Tablets.
