Determination of Contents of Five Components in Descurainiae Semen Before and After Being Processed by HPLC
HPLC for the determination of five components in Descurainiae Semen was established to investigate the change rule of contents of five components in the herb before and after being processed.
Method:

column(4.6 mm×250 mm
5 μm) was employed
and the mobile phase was acetonitrile(A)-1% acetic acid aqueous solution(B) for gradient elution(0-5 min
5%-10%A; 5-15 min
10%-13%A; 15-23 min
13%-20%A; 23-43 min
20%-25%A; 43-46 min
25%A; 46-55 min
25%-40%A; 55-60 min
40%A). The flow rate was 1 mL·min
-1
.The detection wavelength was set at 265 nm
the injection volume was 10 μL
and the column temperature was 30 ℃.
Result:
2
Contents of the above five components before processing were 0.114 3%
0.041 6%
0.036 2%
0.022 6% and 0.097 6%; after processing
the contents of these five components turn into 0.107 4%
0.011 3%
0.034 2%
0.021 9% and 0.058 9%; among them
the contents of these five components decreased by 6.04%
72.84%
5.52%
3.10% and 39.65%
respectively.
Conclusion:
2
The contents of these five components in Descurainiae Semen is reduced to varying degrees after processing.The contents of phenylpropanoids decrease significantly
while the contents of flavonoid glycosides do not change significantly.
