Abstract:
OBJECTIVE：To establish the fingerprint of Papaveris Pericarpium， and to determine the contents of 5 components，such as morphine ，codeine，thebaine，papaverine and narcotine. METHODS ：HPLC method was adopted. The determination was performed on a Agilent ZORBAX Eclipse XDB-C18 column with mobile phase consisted methanol -sodium heptanesulfonate with gradient elution at the flow rate of 1.0 mL/min. The detection wavelength were set at 238 nm（papaverine） and 216 nm（morphine，codeine，narcotine，thebaine）. The column temperature was 20 ℃，and sample size was 10 µL. HPLC fingerprints of 15 batches of Papaveris Pericarpium were established by using the Similarity Evaluation System of TCM Chromatographic Fingerprints （2012 edition），and the common peaks were determined in combination with the spectra of mixed control. The contents of morphine ，codeine，thebaine，papaverine and narcotine were determined simultaneously by the same method. The cluster analysis was conducted by using SPSS 19.0 software. RESULTS ：There were 13 common peaks in 15 batches of Papaveris Pericarpium ，and the similarity was greater than 0.99. Five chromatographic peaks were identified ，which were morphine，codeine，thebaine，papaverine and narcotin. The results of cluster analysis showed that 15 batches of Papaveris Pericarpium could be clustered into two categories ，S1-S7 and S 8-S15，belonging to two cities. The linear ranges of five components were 10.21-102.10，10.43-104.30，1.54-30.70，2.36-47.28，2.32-57.90 μg/mL，respectively（all r＞0.998）. RSDs of precision，stability（24 h）and repeatability tests were all less than 2％. The average recoveries were 99.46％（RSD＝1.08％，n＝ 6），97.84％（RSD＝1.55％，n＝6），91.10％（RSD＝1.74％，n＝6），96.43％（RSD＝1.25％，n＝6）、94.82％（RSD＝1.20％，n＝6）， respectively. The contents of 5 components were 2.342 9-4.082 2，0.430 4-0.889 7，0.055 2-0.090 4，0.299 3-0.558 8，0.343 2- 0.656 2 mg/g. CONCLUSIONS ：The established HPLC fingerprint and content determination method is simple ，feasible，sensitive and accurate. It combined with the cluster analysis could reflect characteristics and int ernal quality of chemical components in Papaveris Pericarpium . Papaveris Pericarpium in different cities possess regionalization characteristics ，but its quality isbasically stable.
