Effect of Steaming Time and Pressure on Contents of Six Ginsenosides in Ginseng Radix et Rhizoma by UPLC-QqQ-MS/MS增强出版
The processing method of red ginseng was determined by comparing the effects of different steaming time and pressure on the total content of six ginsenosides.

column (2.1 mm×100 mm
1.7 μm) was used. The mobile phase was 0.1% formic acid aqueous solution (A) and 0.1% formic acid acetonitrile solution (B) for gradient elution (0-4 min

Result:
2
When the steaming time was 3 hours
the total mass fraction of six ginsenosides in each sample group was 7.099 8-16.768 5 mg·g
-1
and the total amount of the six ginsenosides in atmospheric steaming was 2.5-12.6 times of that in pressurized steaming
which was obviously better than that in pressurized steaming.
Conclusion:
2
Under the conditions of this experiment
the best processing method of red ginseng is atmospheric steaming for 3 hours with fresh ginseng.
