Investigation of Spectrum-effect Relationship of Brain Protection of Shaoyao Gancaotang on Epileptic Mice Based on Grey Correlation Analysis
To investigate the spectrum-effect relationship of effect of material components in Shaoyao Gancaotang on the levels of malondialdehyde (MDA)
superoxide dismutase (SOD) and adenosine triphosphatase (ATPase) in brain tissue of epileptic mice
and to reveal the material basis of the antiepileptic effect of Shaoyao Gancaotang.
Method
2
HPLC was used to establish the fingerprint of 15 batches of Shaoyao Gancaotang
the mobile phase was consisted of acetonitrile (A)-0.1% phosphoric acid aqueous solution (B) for gradient elution (0-15 min
19%A; 15-45 min
19%A-50%A; 45-46 min
50%A-90%A; 46-48 min
90%A)
the flow rate was 1.0 mL·min
-1
and the detection wavelength was 237 nm. The mouse epilepsy model was induced by penicillin
the protective effect of 15 batches of Shaoyao Gancaotang on MDA
SOD and ATPase levels in brain tissue of epileptic mice was investigated. Grey correlation analysis was used to analyze the correlation between the peak areas of characteristic peaks in the fingerprint of 15 batches of Shaoyao Gancaotang and three pharmacodynamic indexes (the activities of MDA
SOD and ATPase)
and the mathematical model of spectrum-effect relationship between different material components and pharmacodynamic indexes was established.
Result
2
Shaoyao Gancaotang could increase the contents of ATPase and SOD and reduce the content of MDA in the brain tissue of epileptic mice
and most of the differences were significant (
P
<
0.05
P
<
0.01). There were 28 common peaks in the fingerprint of 15 batches of Shaoyao Gancaotang
and 15 of them were characteristic peaks. Grey correlation analysis found that the characteristic peaks contributed to the activities of MDA
SOD and ATPase included peak 2 (albiflorin)
peak 3 (paeoniflorin)
peak 5 (liquiritin)
and so on
the specific ranking was peak 3
>
peak 6
>
peak 12
>
peak 8
>
peak 2
>
peak 5
>
peak 9
>
peak 4
>
peak 10
>
peak 7
>
peak 13
>
peak 11
>
peak 15
>
peak 1
>
peak 14.
Conclusion
2
Shaoyao Gancaotang can affect the activities of SOD
MDA and ATPase in brain tissue of epileptic mice by multi-component synergy. Simultaneously
introducing the grey correlation analysis into the correlation evaluation of the spectrum-effect relationship between components and efficacy of Chinese herbal compounds
it can objectively reflect the essence of the synergistic action of multiple components in traditional Chinese medicine (TCM)
and it is an effective analysis method for screening and predicting the pharmacodynamic components of TCM.
