HPLC Fingerprint Analysis of Liposoluble and Water-soluble Fractions of Xiaojinwan
High performance liquid chromatography (HPLC) fingerprints of liposoluble and water-soluble fractions of Xiaojinwan were established and the similarity of fingerprints was evaluated
so as to explore the quality consistency of Xiaojinwan.
Method
2
Chromatographic separation was carried out on Welch Ultimate AQ-C
18
column (4.6 mm×250 mm
5 μm) with the mobile phase of 0.1% phosphoric acid solution (A)-acetonitrile (B) for gradient elution (liposoluble fraction of 0-5 min
40%B; 5-10 min
40%-50%B; 10-20 min
50%-60%B; 20-30 min
60%-65%B; 30-40 min
65%-70%B; 40-50 min
70%-80%B; 50-60 min
80%-90%B; 60-65 min
90%-95%B; 65-75 min
95%-100%B; 75-80 min
100%B; water-soluble fraction of 0-20 min
2%-5%B; 20-30 min
5%-10%B; 30-37 min
10%-20%B; 37-45 min
20%-30%B; 45-50 min
30%-40%B; 50-58 min
40%B)
the flow rate was 1 mL·min
-1
the column temperature was 30 ℃. The detection wavelengths of the liposoluble and water-soluble fractions were 202
250 nm
and their injection volumes were 10
20 μL
respectively. A total of 30 batches of Xiaojinwan from five manufacturers were detected by HPLC
the chromatographic peaks of each part were analyzed by principal component analysis (PCA) and identified.
Result
2
A total of 55 chromatographic peaks were detected in the fingerprints
and the similarity of fingerprint of 30 batches of Xiaojinwan was quite different. The relative standard deviations (RSDs) of fingerprint similarity of liposoluble and water-soluble fractions of Xiaojinwan were 21.5% and 32.8%
respectively. There were significant differences in the quality of samples from different manufacturers and the same manufacturer
and the chemical consistency evaluation results were dominated by liposoluble fraction
and the main reason for the chemical difference of this preparation was the composition of Liquidambaris Resina.
Conclusion
2
The quality consistency of Xiaojinwan is poor. The establishment of two-fraction fingerprint provides a new idea for the overall quality evaluation and control of Xiaojinwan
and can provide a reference for the quality consistency evaluation of traditional pills.
