Objective:
To analyze ginsenosides composition in wild ginseng leaves with different growth years.
Method:
The analysis was performed on Acquity UPLC BEH Shield RP18 (2.1 mm x 100 mm, 1.7 microm) column, the mobile phase was acetonitrile-0.05% formic acid solution in gradient elution mode. The detection wavelength was at 203 nm. The flow rate was 0.4 mL x min(-1) and column temperature was set at 30 degrees C.
Result:
Thirteen ginsenosides were determined by the established UPLC method. In 5-17th growth year ginseng leaf samples cultivated simulating wild conditions, the contents of ginsenosides in the 14th year have the highest content.
Conclusion:
The established method is simple, accurate and reliable, can be used in ginsenosides determination and fingerprint research of Panax crude drug. The result provides reliable data for the accumulation of ginsenosides and sustainable utilization of ginseng resources.
