Grade Evaluation of Magnoliae Officinalis Cortex Processed with Ginger Juice Based on Relative Quality Constant
To establish the grade evaluation standard for Magnoliae Officinalis Cortex processed with ginger juice by combining traditional morphology evaluation with modern intrinsic quality evaluation.
Method:
2
The morphological parameters and contents of intrinsic pharmacodynamic index components of 28 batches of Magnoliae Officinalis Cortex processed with ginger juice were determined
and the relative quality constants were calculated. Assuming that the average relative quality constant was 100%
more than 120%of the samples were classified as the first grade
60%to 120%as the second grade
the remaining as the third grade.
Result:
2
The relative quality constant of Magnoliae Officinalis Cortex processed with ginger juice ranged from 0.09 to 1.78. The relative quality constant of the first grade was ≥0.64
the second grade was 0.32-0.64
while the third grade was ≤0.32.
Conclusion:
2
Relative quality constant combines external indexes of traditional morphology and internal indexes of pharmacodynamic components
which can objectively
reasonably and scientifically classify the grade of Magnoliae Officinalis Cortex processed with ginger juice
and provide reference for establishing and improving the grade evaluation standard of this decoction pieces.
