| Abstract: | OBJECTIVE: To determine 15 organochlorine pesticide residues in Astragalus membranaceus, Panax notoginseng and P. quinquefolium. METHODS: The 15 organochlorine pesticides were extracted from samples with mixed solvents by ultrasonication, cleaned up by a column packed with Florisil, and then separated by capillary gas chromatography with electron capture detector(CGC-ECD). The capillary column was DB-5(15 m x 0.32 mm x 0.25 microns); injector temperature 240 degrees C; detector temperature 320 degrees C; the column temperature program initial 100 degrees C (hold 0.5 min), rate of 20 degrees C min-1 to 210 degrees C (hold 0.5 min), rate of 8 degrees C min-1 to 240 degrees C (hold 10 min). The column head-pressure was 58.84 kPa. The injection was splitless and the injection volume was 1 microliter. RESULT AND CONCLUSION: The average recoveries and RSD are in the range of 78.30%-130.1% and 0.75%-31.9% at two spiked mixed organochlorine pesticide levels, respectively. All the samples have organochlorine pesticide residues. |
