[Changes of fingerprints with crude and processed cassiae semen in xuezhiling tablets].

[Article in Chinese]

Abstract

OBJECTIVE:

To establish an effective and convenient method for HPLC fingerprints of Xuezhiling tablets and new Xuezhiling tablets, and to observe the changes of fingerprint with crude and processed Cassiae Semen in Xuezhiling tablets.

METHODS:

The HPLC with Agilent TC-C18 (4.6 mm x 250 mm, 5 microm) column was used for the gradient elution of acetonitrile-0.1% phosphoric acid solution, at the flow rate of 1.0 mL/min. Detection wavelength was set at 284 nm and the column temperature was 30 degrees C.

RESULTS:

Ten batches of Xuezhiling tablets and new Xuezhiling tablets were tested and gained HPLC fingerprint containing 20 common peaks, respectively.

CONCLUSION:

This method is stable and reliable. The number of common peaks of fingerprint had little change after the crude and processed Cassiae Semen in Xuezhiling tablets interchangeably, but the contents of some components had significant changes.
