Objective:To establish a method for the determination of estragole in anise oil. Method:The essential oil was extracted from Illicium verum and then analyzed by GC. the GC was fitted with HP-INNOWax capillary column (0.32 mm×30 m×0.50 μm) film thickness; flame ionization detector and operated under the following conditions:Nitrogen carrier gas; split injection 100:1; temperature programming. Result:The calibration curves were linear in the range of 0.08-0.32 μg for estragole
r=0.999 8
average recovery of estragole was 101.0%
RSD was 1.27%(n=9). Conclusion:The method is simple
accurate
reproducible and can be used as the quality control for Illicium verum.
