ABSTRACT

Objective:

To establish HPLC fingerprints of Huagai San and identificate the characteristic peaks ion and preparations- medicinal materials peak pattern matching.

Methods:

Similarity on 12 batches of Huagai San was estimated, and peak pattern matching of the original medicine was conducted. Sample extraction with methanol in ultrasonic condition was carried out. HPLC- DAD methods were developed, detection wave length was set at 280 nm, HPLC mobile phase consisted of acetonitrile-0.2% phosphate acid aqueous solution, volume flow-rate was delivered at 0.6 mL/min, and column temperature was kept at 30℃. Cluster analysis of 12 batches of Huagai San was analyzed by SPSS 19.0.

Results:

The results showed that 26 common peaks were defined, the peaks No. 4, 5, 10, 17, 18, 20, and 21 were ephedrine hydrochloride, pseudoephedrine hydrochloride, chlorogenic acid, liquiritin, glycyrrhizic acid, narirutin, and hesperidin, respectively, and peak pattern matching showed that Huagai San had 6, 3, 6, 1, 4, and 1 matching peaks with Ephedrae Herba, Mori Cortex, Citri Reticulatae Pericarpium, Armeniacae Semen Amarum, Glycyrrhizae Radix et Rhizoma, and Perillae Fructus, respectively. The fingerprint similarity among the samples was all over 0.960. All the samples were classified into three categories.

Conclusion:

Similarity evaluation combined with the peak matching of fingerprint for Huagai San could provide the scientific methods for its identification and quality control.
