Abstract:
Objective To establish characteristic spectrum of ginsenosides in Panax quinquefolium from Liuba. Methods Using C_(18) solid phase-extraction cartridges, main ginsenosides from 40% ethanol extracts of P. quinquefolium were purified. Then the samples were analyzed by HPLC-EMS. Results(From the) total ion spectrum of P. quinquefolium, 3 stronger peaks were selected. Based on them, characteristic corresponding spectrum of ginsenosides in P. quinquefolium from Liuba was established. Conclusion This method has reliable reproducibility and precision. Its simple pretreatment, easily operation, and rapidly analytic procedure show that this method is suitable for identifying P. quinquefolium.
