Effect of Manual and Machine Decocting on Chemical Constituents in Bazhentang Based on Non-targeted Metabolomics
To evaluate the effect of manual decocting and machine decocting on the chemical constituents in Bazhentang based on non-targeted metabolomics
and to find the differential chemical constituents of these two decocting methods.
Method:
2
Bazhentang was boiled by standardized manual decocting and machine decocting methods
respectively. Orthogonal partial least square-discriminate analysis(OPLS-DA) and other multivariate statistical methods
combined with variable importance in the projection(VIP) value and
t
-test
were employed to analyze the effect of two decocting methods on the chemical constituents in Bazhentang. The differential chemical constituents were analyzed by UPLC-LTQ-Orbitrap MS under positive and negative ion modes
mobile phase was acetonitrile-0.1%formic acid aqueous solution for gradient elution
the scanning range was
m
/
z
50-1 500.
Result:
2
Under the positive and negative ion modes of high-resolution mass spectrometry
a total of 87 differential components were found
40 of them were identified according to the mass spectrometry data and literature reports
including senkyunolide A
glycyrrhizin
ferulic acid
etc.
Conclusion:
2
Based on the analysis of color and chemical compositions of Bazhentang
there are obvious differences between the standardized manual decocting and machine decocting. If the advantages of these two methods are combined
a standardized decoction process can be established on the basis of maintaining the advantages of manual decocting
the effectiveness of traditional Chinese medicine decoction will be maximized and it will be convenient for patients to take it.
