Exploration of Combinational Quality Control Method of Carbonized Ginger Based on HPLC Fingerprint and QAMS
To establish the HPLC fingerprint of carbonized ginger and to determine the contents of zingerone
6-gingerol
6-shogaol
10-gingerol
8-shogaol and 10-shogaol with quantitative analysis of multi-components by single marker (QAMS).
Method:
2
The fingerprint of carbonized ginger was established by HPLC. All samples were analyzed by Waters SymmetryShield™ RP18 column (4.6 mm×250 mm
5 μm) with gradient elution by acetonitrile(A)-water(B) (0-30 min
25%-70%A; 30-50 min
70%-90%A; 50-60 min
90%A)
the flow rate was 1.0 mL·min
-1
the detection wavelength was set at 240 nm and the column temperature was 30 ℃. Zingerone
6-gingerol
8-gingerol
6-shogaol
10-gingerol
8-shogaol and 10-shogaol was chosen as marker ingredients to establish HPLC fingerprint of carbonized ginger decoction pieces. Taking 6-gingerol as internal reference standard
the contents of zingerone
6-shogaol
10-gingerol
8-shogaol and 10-shogaol were determined at the detection wavelength of 220 nm and 280 nm according to the relative correction factor.
Result:
2
The HPLC fingerprint of carbonized ginger was obtained and 10 common peaks were designated
and 7 of them were identified as zingerone
6-gingerol
8-gingerol
6-shogaol
10-gingerol
8-shogaol and 10-shogaol
respectively. And there were no significant differences between the quantitative results of external standard method and QAMS. It is suggested that the content limits of carbonized ginger should be not less than 0.020%of zingerone (C

respectively.
Conclusion:
2
The developed method is accurate and feasible
which can provide a simple and effective method for the quality control of carbonized ginger.
