| Abstract: | Objective Making a suitable method for determination of quintozene in panax by GC-MS. Methods The quintozene in sample was extracted with acetone- n-hexane, purified and condensed by oil of vitriol, then determinated by GC-MS and El. Results The detection limit is 0.004mg/kg; the exactitude is 5.0-7.2%; the callback rate is 86.5%-90.4%. Conclusion The method described here showed a high efficiency and sensitivity, and a good stability and reliability. |
