| Abstract: | A method for the determination of six pyrethrins from natural pyrethrum extracts by capillary gas chromatography with FID detector was described.Dibutyl phthalate was used as an internal standard,and the linear range was 0.1～ 1.0 g/L with linear regression coefficient of 0.9958～ 0.9964,average recovery of 99.50% and RSD of 1.10%(n=5).Result showed that the method was accurate,reliable and rapid,and could be used for the quality control of natural pyrethrins. |
