Chemical Consistency of Lycii Cortex from Different Origins Based on Component Contents and Fingerprint增强出版
In this study, the two different origins of Lycii Cortex in the 2020 edition of
Chinese Pharmacopoeia
were determined to analyze their chemical consistency by comparing their main chemical composition.
Method
2
Thirty representative batches of Lycii Cortex were collected, content determination and fingerprint analysis methods were established by ultra performance liquid chromatography-photodiode array detector (UPLC-PDA) combining with multivariate statistical analysis to evaluate the similarities and differences between two origins of Lycii Cortex. Respectively by the mobile phase of acetonitrile (A)-0.15% trifluoroacetic acid aqueous solution (B) and the mobile phase of acetonitrile (A)-0.1% formic acid aqueous solution (B) for gradient elution (0-4 min, 5%-12%A; 4-8 min, 12%A; 8-12 min, 12%-14%A; 12-15 min, 14%-30%A; 15-17 min, 30%-40%A; 17-18 min, 40%-90%A), and the detection wavelength was set at 280 nm.
Result
2
This established content determination and fingerprint methods had good precision, stability and repeatability. The similarities of 30 batches of Lycii Cortex were above 0.90 by comparing with the control fingerprint, and the eight common peaks in fingerprints of Lycii Cortex from
-bis (caffeoyl) spermidine and lyciumin A. Among them, the content ranges of kukoamine B in Lycii Cortex from
L. chinense
and
L. barbarum
were 1.22%-8.18%, 2.52%-12.24%, respectively.
Conclusion
2
The established UPLC analysis method can be used for the content determination and fingerprint analysis of Lycii Cortex. This study indicates that chemical contour of Lycii Cortex from
L. barbarum
and
L. chinense
are similar, there are no significant differences in kukoamine B content, and they have consistency in the chemical composition.
