Spectrum-effect Model of Salvia miltiorrhiza Stem and Leaves Based on Enzymatic Activity
in order to investigate the correlation between the chromatographic peaks and the blood circulation activity in the HPLC fingerprint
and establish and verify the activity spectrum-effect model based on enzyme activity.
Method:
2
HPLC method and fibrinogen plate method were used to determine the fingerprint and
in vitro
activity values of stems and leaves of
S
.
miltiorrhiza
in 6 batches. SPSS was used to establish its spectrum-effect model by the principal component analysis-correlation analysis-multiple linear regression analysis method
and six batches of
S
.
miltiorrhiza
stems and leaves were used to verify the model.
Result:
2
Totally 7 characteristic peaks were obtained in the fingerprints of
S
.
miltiorrhiza
leaves. Kendalls tau-b correlation analysis showed the correlations between the blood circulating activity of
S
.
miltiorrhiza
stems and leaves and the 7 characteristic peak areas. The steep slope map analysis showed five optimal principal components of the model
namely protocatechualdehyde
caffeic acid
common peak 5 (to be identified)
rosmarinic acid and salvianolic acid B. Among them
protocatechualdehyde
common peak 5 and salvianolic acid B showed a positive correlation with the activity of blood circulation
while caffeic acid and rosmarinic acid showed a negative correlation with the activity of blood circulation
with low mean relative errors between the predicted value and the measured value.
Conclusion:
2
The blood circulation activity spectrum-effect model based on enzyme activity can predict the blood circulation activity of stems and leaves of
