To prepare standard decoction of Saposhnikoviae Radix pieces
and conduct a study on the quality standards
in order to provide the scientific reference for the study of clinical application and other decoction standard decoctions.
Method:
2
By the traditional water decocting method
11 batches of standard decoction of Saposhnikoviae Radix pieces were prepared to determine pH
prim-
O
-glucosylcimifugin and 4′-
O
-
β
-
D
-glucosyl-5-
O
-methylvisamminol content
calculate the paste rate and transfer rate
and investigate the feasibility of the measurement method. An analytical method for HPLC fingerprint was established. Hypersil ODS2 column (4.6 mm×250 mm
5 μm) was adopted and eluted with methanol-water as the mobile phase in a gradient mode. The detection wavelength was 254 nm
the flow rate was 1 mL·min
-1
and the column temperature was 25 ℃. The fingerprint analysis method was used to evaluate the similarity of the 11 batches of standard decoction of Saposhnikoviae Radix pieces.
Result:
2
Through the determination of 11 batches of standard decoctions of Saposhnikoviae Radix pieces
the average pH value was 5.5
the paste-out rates were between 34.3% and 46.3%
and the average paste-out rate was 41.4%
the standard deviation was 3.7%
the transfer rate of prim-
O
-glucosylcimifugin was 66.8%-93.5%
the average metastasis rate was 79.4%
the standard deviation was 12.1%
the transfer rate of 4′-
O
-
β
-
D
-glucosyl-5-
O
-methylvisamminol was 70.4%-98.2%
the average transfer rate was 83.40%
the standard deviation of 10.8%. The results of various methodological studies were consistent with the requirements of RSD. The fingerprinting analysis was performed using similarity evaluation software for traditional Chinese medicine fingerprints
and 9 principal common peaks were identified. The similarity was higher than 0.9.
Conclusion:
2
The quality evaluation method established in this study has a good stability
precision and repeatability. The fingerprints have a high similarity
which is suitable for the quality evaluation of standard decoctions of Saposhnikoviae Radix pieces
and can provide the scientific basis for the quality evaluation of other related preparations.
